I’m not going to tell you which town I just left. That’s next week’s post, once I’ve had time to do it justice. But the trip was good enough that I wanted to write about onsen health benefits first, while the feeling is still fresh, and before the specific place distracts from the bigger question: how much of this is real, medically, and how much is just a genuinely good two days off?

Here’s what’s actually in this guide:

• What is Onsen

• Where onsen culture comes from, and why the tōji tradition matters more than people think

• What the research actually supports for sleep, pain and mood, and what it doesn’t

• Who should be careful, and the safe way to get in and out of a hot bath

What is an Onsen

In Japan, “onsen” (温泉) is a legal term, not just a feeling. Under the Hot Springs Act of 1948, water or gas that comes out of the ground counts as an onsen if it’s 25°C or warmer at the source, or if it contains at least one of 19 listed substances above a set amount (source).

Here’s the confusing part. A neighborhood public bathhouse, a sento (銭湯), is usually just tap water heated in a boiler. It can be just as hot, just as communal, and just as relaxing as an onsen, but because the water isn’t coming from a natural spring, it doesn’t legally count as one.

Meanwhile, a spring that’s barely lukewarm can legally be an onsen, as long as it carries the right minerals. What you feel in the water and what the law calls the water are two different things.

Japan has more than 3,000 onsen resorts, according to a 2016 Ministry of the Environment survey (source).

Where onsen culture comes from

People have soaked in Japan’s volcanic springs for a very long time. Dogo Onsen in Ehime is reputed to be the oldest, tied to legends of early emperors. Buddhist monks used springs for purification, and farmers and fishermen took ritual baths at set times of the year.

The tradition that matters most to me, as a doctor, is tōji (湯治): historically, spending days or weeks at a hot spring town specifically to rest and recover, often at simple inns where guests cooked their own meals. It wasn’t a vacation in the way we use the word now. It was closer to a prescribed rest cure, water included.

A short onsen trip today, even just one night away, is a small echo of that older idea. You sleep more, eat slower, and step outside your normal routine for a day or two. I think that context deserves as much credit for how good you feel afterward as the mineral content does.

What the research actually shows about onsen health benefits

Here’s what I’d tell a friend, based on the studies I could verify, with the mechanism behind each claim where one is known.

• Sleep. Warm water raises your skin temperature, and the drop in core body temperature after you get out is one of the body’s natural cues for sleep onset, the same reason a warm bath or shower before bed is recommended almost everywhere in the world. In studies of Japanese-style bathing specifically, soaking to the shoulders in the evening has been reported to improve sleep quality and shorten the time it takes to fall asleep, especially in winter (source).

• Pain and stiff joints. Heat increases blood flow to muscles and joints, and the water’s buoyancy takes weight off them at the same time. Systematic reviews suggest spring bathing has a modest positive effect on chronic pain and musculoskeletal conditions.

• Stress and mood. Warm water bathing shifts the nervous system toward its “rest and digest” side. A review of 22 controlled studies found improvements in depression, sleep problems and stress this way. Anxiety improved in some studies but not all (source).

• Blood pressure. Hot water widens blood vessels, so pressure drops during and after a bath. In one Japanese study of older adults, night-time hot spring bathing was associated with lower systolic blood pressure (source). That was a retrospective study, so it shows an association, not proof.

  

That’s the general research, the kind that applies to onsen as a category. What it can’t tell you is which specific spring, at which specific onsen town, is actually worth planning a trip around for a specific effect: which one is genuinely known for muscle recovery, which one for skin, which one for circulation, and why.

That’s what this week’s paid post covers: real onsen towns and facilities I’ve actually been to, matched to what they’re each genuinely good for. If you’re planning a trip to Japan, or you just love onsen as much as I do, that one’s worth subscribing for.

Who should be careful

Most healthy adults soak without trouble. Some people should check with a doctor first, or skip the bath entirely.

Japan’s Ministry of the Environment lists contraindications that onsen facilities must post, so read the sign in the changing room. They include acute illness with fever and unstable heart or respiratory disease. Pregnancy was on that list until 2014, when the ministry removed it after finding no scientific evidence that soaking endangers pregnancy (source).

If you have high blood pressure or a heart condition and aren’t sure where you stand, get it checked before your trip. A health screening in Japan can do that; see my guide to ningen dock for foreign travelers, or start with What Is a Ningen Dock?.

How to bathe safely

Here are a few practical notes for visitors.

1. Pour water over your body first. Start with your feet and legs, then your torso. Etiquette and physiology agree here.

2. Watch the water temperature.

3. Don’t stand up fast. Pause, then rise slowly.

4. Don’t bathe drunk or right after a big meal. Be careful after sedatives or sleeping pills.

5. Drink water before and after.

6. Get out at the first sign of dizziness, a pounding heart or nausea.

Onsen etiquette for foreigners

The rules are simple, and Japanese bathers will appreciate you following them.

• Wash thoroughly at the washing stations before you enter the bath.

• Keep your towel out of the water. Leave it on the edge or fold it on your head.

• Tie up long hair.

• No swimsuits in most public baths.

• Keep your voice low, and don’t swim.

Tattoos are the question visitors ask most, and many onsen still refuse them. In a 2015 Japan Tourism Agency survey, 56% of facilities refused tattooed guests, 31% allowed them, and 13% allowed them with conditions such as covering the tattoo (source).

What has changed more recently is the workaround: skin-tone cover-up stickers and patches for small tattoos are now offered at some facilities, and can be enough to get you into a communal bath that would otherwise turn you away. It’s worth asking at the front desk if you have a small piece. Private baths and rooms with their own bath sidestep the question entirely.

A guide to onsen spring types

Signs at an onsen usually name the spring type, and it’s worth learning to read them. The type changes how the water actually feels, and the posted sign is also where any cautions specific to that spring get listed.

Japan classifies onsen water into roughly ten categories based on their dominant minerals. Here are the eight you’re most likely to run into as a visitor.

Do onsen actually help with back pain or muscle soreness?

There’s reasonable evidence for chronic pain and stiff joints in general, and plenty of people, myself included this week, feel real relief after a soak. I wouldn’t call it a treatment for a specific injury. If pain is severe, sudden, or doesn’t improve, see a doctor rather than relying on a bath.

That’s the medical case for onsen, as honestly as I can put it: modest, real, and worth much less hype than the signs by the bath suggest.

The specific, by-the-town version is in this week's paid post: Japan's three classic onsen rankings (one of them over 400 years old, and still the fastest way to get oriented), which real, named towns are actually famous for which spring type, and my honest read on which of those reputations hold up and which don't. And next week, in a free post, I'll finally tell you about the best onsen town I've been to yet, the one I mentioned at the start of this piece.

Frequently Asked Questions

What are the real onsen health benefits?

For most healthy adults, onsen are good for relaxation, sleep and possibly aches and stiffness. Claims beyond that, such as detox or “cleansing the blood”, aren’t supported. The main risks are temperature swings, overheating and dehydration, not the water itself.

Can you go to an onsen with a tattoo?

Sometimes. Policies vary by facility, and many still refuse tattoos, though cover-up stickers are becoming more common for small tattoos. Private baths and in-room baths are the reliable option.

How long should you stay in an onsen?

Japan’s Consumer Affairs Agency suggests no more than 10 minutes at 41°C or lower. Shorter is better in hotter water. Leave before you feel flushed, sluggish or your heart starts pounding.

Is it safe to go to an onsen when pregnant?

Japan removed its blanket warning in 2014. For a healthy, low-risk pregnancy, short soaks in lukewarm water are generally considered acceptable, but overheating, dehydration and slipping are the concerns.

Can you go to an onsen with high blood pressure?

Many people with well-controlled blood pressure do. Talk to your doctor first, avoid very hot water, and choose a short, gentle soak. If your blood pressure or heart condition is unstable, skip it.

Do you have to be naked in an onsen?

In most public baths, yes. Swimsuits aren’t allowed. If that isn’t for you, a private bath or a room with its own bath is a good alternative.

This one is different. No studies, no citations, no hedging. Just seven places in Tokyo I keep coming back to, on my own time, with my own money, and why.

I didn’t put this list together by searching “best matcha cafes Tokyo” and cross-referencing star ratings. Every place here is somewhere I’ve actually sat down, ordered, and gone back to more than once — some of them so many times I’ve lost count. A couple of these I’ve already written full reviews for, so I’ll keep those two short and point you to the longer piece instead of repeating myself. The other five, you’re getting for the first time here, and I’ve been sitting on them for a while.

The two I’ve already told you about

1. Tokyo Little House Café

I wrote a full review of this one already, so go there for the full details on the space, the menu, and everything that makes it worth the trip. The short version: it’s a quiet, beautifully designed café inside a converted old house, and the matcha itself is genuinely excellent — not just a pretty backdrop for photos. It’s one of those rare places where the aesthetics and the actual quality of what’s in the cup match each other, which is honestly less common than you’d hope in a city this photogenic.

Nearest station: Akasaka Station (Chiyoda Line) or Tameike-sanno Station — both a short walk

2. HOTEL 1899 TOKYO

Same story here — I’ve already written this one up in detail, so I won’t repeat myself. This is a hotel built entirely around a tea concept, and even if you’re not staying the night, the tea bar alone is worth going out of your way for. It’s one of the very few places in Tokyo where matcha is treated with the same seriousness and ceremony that a proper cocktail bar treats spirits — the staff talk you through what you’re drinking instead of just handing it over, which changes the whole experience.

Nearest station: Shimbashi Station or Hamamatsucho Station — both within walking distance

Now, the five I’ve never written about before

These are the ones I’ve genuinely been saving. No particular ranking here — I’ve ordered them the way they came to mind, not by how much I like them, because honestly I couldn’t rank them if I tried. Each one earned its spot for a completely different reason, which is part of why I keep going back to all five.

As a doctor practicing in Japan, where matcha isn’t a trend but a few-hundred-year-old part of daily life, I wanted to actually go through the claims people repeat most — the good and the exaggerated — and tell you honestly which ones hold up, with the actual research behind each one.

In this article:

• What matcha actually is, and why it’s different from steeped green tea

• ✅ Four real, source-backed reasons matcha is worth drinking

• ❌ Three claims that are exaggerated or unsupported by human research

• How to actually buy good matcha

(If you want the full rundown of Japanese tea types — sencha, hojicha, gyokuro, and where matcha fits among them — I covered that in detail here. This article focuses specifically on what matcha does for your body.)

Full disclosure before we start: I’m not a neutral party here. I genuinely love matcha — I have it about once a week, usually on a slow weekend morning, whisked plain with no milk. So take my enthusiasm for what it is. That’s exactly why I wanted to actually check what I could defend as a doctor versus what I just like believing as a fan.

What matcha actually is, in one sentence

Matcha and steeped green tea come from the exact same plant, Camellia sinensis. The difference is entirely in how you consume it: with steeped tea, you infuse the leaves in hot water and drink the liquid, discarding the leaf. With matcha, the leaf is stone-ground into a fine powder and you drink the entire leaf, suspended in water. That one difference — whole leaf vs. infusion — is the reason for almost everything else in this article.

✅1–✅4: What’s actually true — four real reasons matcha is worth drinking

✅1. You get far more catechins than steeped tea — and there’s genuine human evidence behind them

Matcha is rich in catechins, a family of plant polyphenols, and the most researched of them is EGCG (epigallocatechin gallate). This comes down to the whole-leaf difference: when you steep green tea, only a portion of what’s inside the leaf actually makes it into your cup, and the rest stays behind in the leaf you throw away. Research on the powdering process of tea leaves found that grinding leaves into powder (the matcha method) more than tripled the extractable concentration of EGCG compared to steeping the same leaf whole, according to a peer-reviewed 2018 study published in Nutrients — meaning matcha delivers roughly 2–3 times the EGCG of a typical steeped green tea.

Catechins are genuine antioxidants — they help neutralize the reactive oxygen species (free radicals) involved in cellular aging — and this isn’t a fringe claim; EGCG is one of the most-studied plant compounds in nutrition science. Here’s the part I actually find most convincing, and it’s specifically human data: a 2014 meta-analysis in Scientific Reports (Nature) pooling 13 randomized controlled trials found that green tea catechins produced a small but statistically significant reduction in blood pressure — roughly 2 mmHg systolic and diastolic. That’s modest, not dramatic, and interestingly the effect was blunted in high-caffeine preparations. But it’s real human trial evidence, which is more than I can say for the weight-loss claim below (❌2) — that one is animal-only. This is the one claim in this whole section I’d call genuinely well-supported rather than just plausible.

✅2. L-theanine makes the caffeine feel different — and calmer

Matcha contains more caffeine than steeped green tea, but it also contains far more L-theanine, an amino acid that slows how quickly your body absorbs that caffeine and independently promotes a relaxed, alert mental state. This isn’t a wellness-industry invention: a double-blind, placebo-controlled study published in Biological Psychology found the L-theanine/caffeine combination measurably improved attention and reduced the “jittery” quality of caffeine alone, and the effect has been replicated in several follow-up trials. This is genuinely the claim I’d stand behind most confidently in this whole article.

Practically, this means matcha sits in a useful middle zone: more sustained focus than a coffee crash, more of a lift than a regular cup of green tea.

✅3. Chlorophyll gives matcha a genuinely different antioxidant profile

Matcha’s vivid green color comes from chlorophyll, and it’s not just cosmetic. Matcha tea bushes are shade-grown for several weeks before harvest, which boosts chlorophyll production. Chlorophyll has antioxidant properties distinct from catechins, and because matcha is whole leaf rather than an infusion, you get far more of it than from steeped tea — which is largely why matcha is such a distinctly deep green compared to a cup of sencha. I’ll flag one thing honestly: chlorophyll’s other commonly claimed effects (deodorizing, detoxifying) rest mostly on old, thin evidence, so I’m keeping this one specifically to the antioxidant role, where the science is on firmer ground.

✅4. You get some genuine trace nutrients you’d otherwise throw away

Because you’re consuming the whole ground leaf, matcha also carries small amounts of vitamins and minerals that stay behind in a discarded tea bag — including vitamin C, vitamin E, and trace minerals like manganese and zinc. I want to be honest about scale here, though: these are trace amounts relative to your daily needs, not a meaningful source of any single nutrient on their own. Matcha is not a multivitamin. It’s a genuine (if small) nutritional bonus on top of the catechin and chlorophyll story — not a headline benefit in itself.

❌1: Myth — matcha “detoxes” your body

I see this word on packaging constantly, and it’s the one that bothers me most as a doctor, because it’s not describing anything real.

Your liver and kidneys detoxify your body, continuously, whether you drink matcha or not. No tea, juice, or supplement adds a meaningful “detox” function on top of organs that are already doing this job every hour of every day. Matcha does contain chlorophyll and catechins that support general cellular health — see the chlorophyll and catechin points above, that part is genuinely true — but “detox” as it’s used in marketing is a word chosen because it sounds like a mechanism, not because there is one.

❌2: Overstated — matcha “boosts your metabolism” enough to matter for weight loss

This is one of the most common matcha marketing claims, and the honest version is much smaller than the version on the label.

A 2022 review of matcha research published in Current Research in Food Science found that matcha’s effects on weight gain, cholesterol, and blood sugar have real support — but almost entirely from animal studies, not human trials. Mice given matcha alongside a high-fat diet gained weight more slowly and showed improved cholesterol and glucose markers. That’s a genuinely interesting signal. But the review’s authors were explicit that rodent metabolism doesn’t map cleanly onto human metabolism, and stated plainly that human randomized trials on matcha specifically — as opposed to green tea catechins generally — remain absent. The honest summary: modest fat-oxidation support around exercise in limited human data, not a metabolism-boosting weight-loss tool.

❌3: Overstated — matcha as a cancer-fighting superfood

This is the one I want to be most careful about, because the underlying science is real but the conclusion people draw from it usually isn’t.

EGCG has shown anti-inflammatory and antioxidant activity in lab and animal studies, and some of that research is genuinely promising. But “shows activity in a petri dish or a mouse” is a long way from “prevents cancer in a person drinking a cup a day,” and the human evidence is far more limited and mixed than the supplement industry implies. I’d file this under: worth continued research, not something to build health decisions around.

How to actually buy good matcha

You don’t need to become an expert, but a few things separate good matcha from marketing:

1. Look for ceremonial grade if you’re drinking it plain, culinary grade if it’s going into a latte or baking — the difference is bitterness and quality of the leaf, not a false hierarchy.

2. Japanese origin, ideally with the growing region named (Uji and Nishio are two well-known ones) — not just “product of Japan” on a bag sourced elsewhere.

3. Beyond that, it's genuinely personal preference. Once you've got a Japanese-origin matcha at the right grade for how you're drinking it, brand, price point, and flavor come down to your own taste — there's no single "correct" answer, just what you actually enjoy drinking.

Frequently Asked Questions

Is matcha actually healthier than regular green tea? It offers more concentrated catechins, chlorophyll, and caffeine because you consume the whole leaf, but “healthier” depends on what you’re optimizing for. Neither is unhealthy; they’re different concentrations of the same base compounds.

How much matcha is safe to drink per day? Most healthy adults can comfortably have 1–2 cups a day within normal caffeine guidelines (under 400mg/day total from all sources). If you’re pregnant, sensitive to caffeine, or on certain medications, check with a doctor first.

Does matcha actually help with weight loss? The evidence for a meaningful metabolic boost is mostly from animal studies, not humans — see ❌2 above. There’s modest human evidence for increased fat oxidation around exercise specifically, but it’s not a substitute for diet and activity.

Is ceremonial-grade matcha worth the extra cost? For drinking it plain (whisked with hot water, no milk or sweetener), yes — the flavor difference is significant. For lattes or baking, culinary grade is genuinely fine and a better value.

Can I drink matcha on an empty stomach? Some people find the tannins and caffeine irritating on an empty stomach. If that’s you, have it after a small meal rather than first thing.

A final word, as a doctor (and as someone who just really likes matcha)

Matcha doesn’t need to be a superfood or a detox drink to be worth having in your routine. The real story — whole-leaf catechins and chlorophyll, a genuinely different caffeine experience thanks to L-theanine, and a quality question that has almost nothing to do with the health claims on the label — is more interesting than the marketing version, not less. My honest take: drink it because you like it and because the sourcing is good, not because of what the packaging promises it will do for you.

• Why Niigata’s seafood is genuinely different from what you’ll get even in Tokyo

• The conveyor-belt sushi restaurant with a national reputation — and the 90-minute line that comes with it

• The standing counter next door that turned out to be the better meal, not just the faster one

• The actual physical reason standing sushi can taste better than anything off a belt

• What I ordered, what it cost, and the honest downside of eating standing up (paid subscribers)

I’d seen Benkei’s name in nearly every “best sushi in Niigata” list I’d read before the trip — English-language travel blogs, Reddit threads, the usual pre-trip research — enough that the conveyor-belt restaurant at Pia Bandai was near the top of my plan before I’d even landed. What actually happened once I got there was a printed queue ticket, a wait estimate that kept climbing, and a very short walk to the counter next door instead — standing room only, same kitchen family, same fish coming off the same morning boats. I didn’t wait 90 minutes. And I’m fairly sure I ate better for it, not just faster — a meal I’m still thinking about days later, made one piece at a time by a chef standing three feet away from me.

Free readers get the full story: why I skipped the line, the standing counter itself, and the actual reason it can taste better than the belt. Paid subscribers get exactly what I ordered, what it cost, and the honest downside of eating standing up. If you’ve made it this far through the free posts and you’re the kind of reader who takes food seriously, this is the one worth unlocking.

Why the Seafood Here Is Genuinely Different

I touched on this in Part 1, so I’ll keep it brief: Niigata sits next to the Sado Strait, a fishing ground between the mainland and Sado Island that’s known for both the volume and variety of what it produces. Combine that with same-day landing and a short distance to the city, and the practical result is fish that’s spent less time between ocean and plate than what you’ll typically find even in Tokyo. Pair that with Sado’s own Koshihikari rice for the shari (sushi rice), and you have the two ingredients that actually make sushi good — the fish and the rice — both sourced locally rather than shipped in.

Benkei, and the Line I Didn’t Wait In

The name behind most of this is Benkei (弁慶), a Sado-born sushi group with several restaurants across Niigata City and the surrounding area today. Its flagship conveyor-belt restaurant at Pia Bandai, on the Niigata City harborfront, has built a genuine national reputation — it’s been recognized at points as a top-rated kaiten-zushi restaurant on Tabelog, Japan’s dominant restaurant review platform, and it regularly shows up on “best kaiten-zushi in Japan” lists put together by food writers and travel sites. What makes it work isn’t a gimmick — it’s sourcing: fish landed at Sado’s fishing ports each morning, brought over by the group’s own supply route, and rice grown in Sado’s low-pesticide paddies.

The catch is the wait. The conveyor belt’s reputation means lines that regularly stretch past an hour, especially on weekends, and I watched the estimated wait time climb the longer I stood there. Right next door, under the same roof, is a standing sushi counter run by the same group — same fish, same rice, prepared to order by a chef working right in front of you, with a much shorter line. That’s where I actually ate, and it turned out to be the better decision, not just the faster one.

The Standing Counter Itself

Tachigui (立ち食い) means exactly what it sounds like — no seats, a counter you eat standing at, and a noticeably faster rhythm than either the conveyor belt or a sit-down restaurant. It has none of the ceremony of a formal sushi counter and none of the wait of the belt next door. You order from a posted menu, the chef makes it in front of you, and you eat it standing, usually in less time than it takes to read this paragraph twice.

What surprised me was how little was actually sacrificed to get that speed. This isn’t a scaled-down, lower-quality version of the sit-down restaurant — it’s explicitly built to be “the same taste as the main restaurant, standing-style,” and that held up. The fish was the same quality I’d have gotten waiting an hour for a seat. The rice, seasoned with Sado’s own vinegar-forward style rather than anything sweet, was identical to what I’d read about the group’s main location. The only thing missing was the seat, and after a few minutes standing at the counter, I didn’t miss it.

Restaurant Info — Standing Sushi Counter, Pia Bandai (Niigata City)

Location: Inside Pia Bandai, Niigata City harborfront, directly adjacent to the group’s conveyor-belt restaurant

Nearest station: Niigata Station, about 15–20 minutes on foot, or a short taxi ride

Seating: None — standing counter only

Reservations: Not accepted; it’s specifically the fast-turnover alternative to the conveyor belt’s line

Price range: Comparable to the conveyor belt, roughly ¥150–¥800+ depending on the item; small sets run ¥2,000–¥2,500

English support: Limited; the posted menu is mostly Japanese, and some items sell out and get crossed off as the day goes on

Best for: Anyone who wants Benkei’s quality without Benkei’s line

Why Standing Sushi Can Actually Taste Better Than the Belt

This is the part I didn’t expect going in: skipping the conveyor belt wasn’t a compromise. In some real, physical ways, a good standing counter is the better version of the same meal.

On a conveyor belt, a piece of nigiri is made, then it travels — sometimes for a while — under a lid, at room temperature, before someone picks it up. At a standing counter, the chef makes it and hands it directly to you, seconds later. For anything served slightly warm, or anything where texture changes quickly once it’s cut, that gap matters more than people think. It’s the difference between “fresh that morning” and “fresh right now,” and once you’ve had the second version, the first one is hard to go back to.

There’s also the ordering itself. On the belt, you take what’s passing, or you flag someone down for something specific. At the standing counter, you’re talking directly to the person making your food, in real time, about what’s actually good that day — which tends to get you dishes you wouldn’t have picked yourself.

Frequently Asked Questions

What is tachigui sushi? A standing sushi bar — no seats, a fast-turnover counter, typically built as a quicker, more casual alternative to a sit-down or conveyor-belt restaurant, often from the same kitchen.

Is the standing sushi counter at Pia Bandai the same quality as the conveyor-belt Benkei next door? Yes, by design — same sourcing, same kitchen group, explicitly built to match the main restaurant’s quality in a faster format.

Do I need a reservation for the standing sushi counter? No. It doesn’t take reservations — that’s the point. It’s the fast alternative to the conveyor belt’s line.

How long is the wait at the conveyor-belt Benkei restaurant? It varies, but waits of an hour or more are common, especially on weekends. The standing counter next door is the practical workaround.

Does standing sushi actually taste different from conveyor-belt sushi? It can. Standing-counter sushi is made and handed to you seconds later rather than traveling under a lid on a belt, which matters most for anything served slightly warm or anything that changes texture quickly once cut.

In this article, as a doctor currently training inside a Japanese hospital, I’ll walk through what actually holds up in the data, what I think gets more credit than it deserves, and the one factor — almost never mentioned in these lists — that I think explains most of the gap. I’ll also show you where Japan’s longevity has real costs, not just headlines, and how it compares to the world’s other so-called “Blue Zones.”

What is really behind Japan’s longevity

Let’s start with the number itself. According to Japan’s Ministry of Health, Labour and Welfare’s 2024 life table, the average life expectancy is 81.09 years for men and 87.13 years for women. Japanese women have held the world’s #1 spot for most of the past three decades; men currently rank 6th globally, just behind Sweden, Switzerland, and Norway.

What the chart above doesn’t show, and what I think matters more than the headline number, is a second figure most longevity articles skip entirely: healthy life expectancy. As of the latest government report, Japanese men can expect about 72.6 healthy years, and women about 75.5. The difference between “years alive” and “years healthy” — roughly 8.5 years for men and 11.6 years for women — is a number I’ll come back to, because it changes how I think the whole question should be asked.

The beliefs everyone has — and how many hold up

When I sorted through what readers told me, the answers clustered into three groups: things that are simply true, things that are true but overstated, and one thing that’s quietly the real story. Let’s go through them honestly, one at a time.

What’s true: diet and walking

Diet.

Yes, the traditional Japanese pattern — fish, tofu, seaweed, vegetables, small portions, minimal processed food — is genuinely protective. Hara hachi bu, the Okinawan habit of eating until 80% full, is a real and useful practice, not a wellness cliché.

But here’s the part that surprises people: Japan is not a low-salt country.

Japan actually sits above the US on sodium, largely thanks to soy sauce, miso, and pickled vegetables — and yet it still out-performs the US on cardiovascular outcomes. The diet works despite this, not because every part of it is optimal. If someone tells you the Japanese diet is flawless, they’re selling you a simplified version of it.

Walking.

This one is simply true, no asterisk needed. Japanese adults average roughly 7,000+ steps a day, meaningfully more than the US average of around 5,000. You don’t need a gym membership when the train station is a 12-minute walk and your apartment doesn’t have a driveway. Movement here isn’t a workout — it’s just how the day is structured.

What’s overestimated: ikigai and social ties

This is the part where I’ll probably get some pushback, and I’m fine with that.

Ikigai

— a sense of purpose — is a lovely concept, and it’s not fake. But I don’t think it’s a major driver of Japan’s longevity numbers, and I say that as someone who lives here, not as an outside skeptic. The uncomfortable truth: loneliness among Japan’s elderly is a serious, worsening problem. In 2024, Japan’s National Police Agency conducted the country’s first full-year national count of people who died alone at home. The number was 76,020 — about 80% of them aged 65 or older. That is not the profile of a society running on deep, protective community bonds.

I’d add one more honest wrinkle here, since it’s directly relevant: Okinawa — the original “blue zone,” the place this whole ikigai story was built on — has itself changed. Public health researchers have documented that younger generations of Okinawans, who grew up on a more Westernized, fast-food-heavy diet than their grandparents, have seen the prefecture’s once-famous longevity advantage narrow relative to the rest of Japan. The story that made Okinawa famous is, at this point, largely a story about people who are no longer under 60.

So: rural pockets of Japan genuinely do have tighter social fabric than most Western cities, and that’s worth something. But generalizing “close community” into “the reason Japan lives long” overstates the case, and the newest data on Okinawa itself makes that case harder to make, not easier.

What I see from the clinician’s side, not the patient’s

Here’s the part that’s easy to miss unless you’re standing where I stand.

Most people encounter Japan’s health system as a patient: you go in, you get checked, you leave with a result. What you don’t see is the volume. On any given week in the hospital where I train, a meaningful share of the people coming through for screening have no symptoms at all. They’re not there because something is wrong. They’re there because it’s the year for their check-up, the way it’s the month for a car inspection — and nobody in the room treats that as unusual.

From the clinician’s side, that changes what “catching something early” actually looks like in practice. It’s not a dramatic save. It’s a slightly elevated number on a routine panel, flagged before the person who owns it has any idea anything is happening. Multiply that across a whole country doing this every year, for decades, and you get a structural advantage that has almost nothing to do with what anyone eats for breakfast.

I think this is the part that deserves to be the headline of the “why do Japanese people live so long” conversation, not a footnote.

The real difference: how early Japan catches disease

Here’s what I actually think explains most of the gap, and it has almost nothing to do with diet.

Japan checks. Constantly, almost reflexively.

This matters medically because the biggest risk factors for the diseases that actually kill people — heart disease, stroke, most cancers — are things a check-up catches before symptoms show up: blood pressure, cholesterol, early tumor markers, blood sugar trending the wrong way. A culture that normalizes checking these numbers every year, without waiting to feel sick first, will structurally produce better outcomes than one that treats a doctor’s visit as something you do only when something already hurts.

I think this is the single most underrated factor in almost every “Japanese longevity” article out there.

How Japan compares to the world’s other “Blue Zones”

You may have heard of the “Blue Zones” — five regions researchers have identified where unusually high numbers of people live past 100: Okinawa (Japan), Sardinia (Italy), Ikaria (Greece), Nicoya (Costa Rica), and Loma Linda, California. It’s worth seeing where Japan actually sits next to the others, because the comparison itself is instructive.

The pattern across all five, including Japan, is less “one secret food” and more “unusually consistent daily structure, sustained over an entire lifetime.” Japan’s national-level advantage — as opposed to Okinawa’s local one — is the only one of the five backed by a country-wide preventive care system, not just a regional lifestyle. That’s the difference I keep coming back to.

The honest downsides

In the spirit of not selling you a fantasy: Japan’s longevity comes with real costs, and I’d rather tell you about them than let you find out later.

• The healthy-years gap is real, and larger for women than men. Living to 87 doesn’t mean 87 healthy years. A long life and a long healthy life are not the same claim, and the chart above makes that gap impossible to ignore.

• Loneliness in old age is a genuine crisis here, not a Western media exaggeration. The systems that catch disease early haven’t solved the problem of catching isolation early — and I don’t think any country has.

How to actually try this yourself

You don’t need to move to Japan to borrow the parts that work.

1. Eat until 80% full, deliberately, especially at dinner — not a diet, just a stopping rule.

2. Build in unavoidable walking — a longer route to the station, parking further away, stairs by default.

3. Get an annual check-up you actually keep, including the numbers most people skip: fasting glucose, LDL cholesterol, blood pressure trend over years, not just one reading.

4. If you’re visiting Japan, consider doing a ningen dock while you’re here. It’s one of the more concrete ways to experience this culture from the inside, not just observe it.

Frequently Asked Questions

Is Japanese longevity mostly genetics? No. Migrant studies consistently show that Japanese-Americans and other diaspora populations lose much of the longevity advantage within one to two generations of adopting a Western diet and lifestyle — a strong sign this is environmental, not genetic.

What do Japanese people actually eat for breakfast? Commonly: rice, miso soup, grilled fish, a small amount of natto or pickles, and green tea. It’s protein- and fiber-forward, low in sugar, and rarely skipped.

Does green tea really do anything? It’s rich in catechins and L-theanine, both associated with modest cardiovascular and metabolic benefits in the research literature. It’s not magic, but it’s also not hype — and it beats a sugary drink at breakfast.

Why do Japanese women live longer than men here, even more than the global gap? Lower smoking rates among women, earlier and more consistent use of preventive screening, and lower rates of alcohol-related liver disease all contribute. It’s a combination, not one factor.

Is Okinawa still the longevity miracle everyone talks about? Less than it used to be. Researchers tracking the “Okinawa paradox” have found the advantage is concentrated in older generations who grew up on the traditional diet — younger Okinawans, raised on more Westernized food, haven’t kept the same edge.

Can a foreigner get a ningen dock in Japan? Yes — no residency or insurance is required at most clinics, though English support varies significantly by facility. This is exactly the kind of logistics I help visitors navigate.

You can read more here.

A final word, as a doctor

If I had to compress this whole article into one sentence, it would be this: Japan doesn’t live longer because of any single ingredient in the diet — it lives longer because it treats “finding a problem early” as a normal part of life, not an emergency.

I picked five, mostly at random, and by the third one I understood something I hadn’t before: sake isn’t one drink. It’s a whole category, the way “wine” is a category, and Niigata makes a specific, recognizable style of it.

This is the deep dive I promised in Part 1. Free readers get the “why Niigata,” “how it’s made,” and the rice-polishing breakdown that most sake guides skip.

Paid subscribers get the rest — my actual visit to Imayotsukasa, Niigata’s oldest sake brewery, the full breakdown of the station tasting experience, and where I’d send you to drink it with food.

Why Niigata Is Japan’s Sake Capital

Sake is, at its simplest, rice, water, koji mold, and yeast. That means the two ingredients that matter most are the same two ingredients Niigata is already famous for: good rice and good water. The prefecture’s snowmelt supplies clean, mineral-light water, and its winters are cold enough to keep fermentation slow and controlled — which, for sake, is a good thing. Slower fermentation generally means a cleaner, more refined result.

That’s also why Niigata has one of the highest concentrations of sake breweries (kura) of any prefecture in the country. It isn’t marketing. It’s geography.

How Sake Is Actually Made, Step by Step

I’m not a brewer, but as a doctor I like understanding what’s actually happening to something before I recommend it to people, and sake-making is a more involved process than most people assume — it isn’t a beer-style single fermentation.

1. Polishing (seimai)

Rice grains are milled down, removing the outer layers that contain fats and proteins that would make the sake taste rougher. The percentage remaining after polishing (seimaibuai) is often printed on the label — the lower the number, the more was polished away.

2. Washing and steaming

Polished rice is washed, soaked, and steamed rather than boiled.

3. Koji-making

A mold (Aspergillus oryzae) is cultivated on part of the steamed rice, converting starch into fermentable sugar.

4. Yeast starter (shubo)

Koji, more steamed rice, water, and yeast are combined into a small starter batch.

5. Main fermentation (moromi)

The starter is expanded in stages over roughly three to four weeks, with koji converting starch to sugar and yeast converting sugar to alcohol at the same time — a process unique to sake, called multiple parallel fermentation.

6. Pressing

The fermented mash is pressed to separate the clear sake from the solid lees (kasu).

7. Filtering, pasteurizing, aging

Most sake is lightly filtered, heat-treated once or twice, and rested before bottling.

That “starch converting to sugar and alcohol at the same time” step is the part that actually surprised me. Beer and wine ferment in a single stage. Sake runs two conversions in the same tank, at the same time — which is part of why it’s a genuinely more technical process than either.

Junmai, Ginjo, Daiginjo: The Rice Difference Nobody Explains

Every sake label carries one of these three words, and almost nobody explains what they actually mean. It comes back to that polishing step (seimai) from the table above, and once you see it laid out, it’s genuinely satisfying to understand.

Junmai (純米)

Pure rice sake — just rice, water, koji, and yeast, no distilled alcohol added. There’s no required polishing minimum. This is the category Imayotsukasa, the brewery I visited, specializes in exclusively — more on that below.

Junmai Ginjo (純米吟醸)

Same pure-rice rule, but at least 40% of each grain has to be polished away before brewing starts — meaning 60% or less of the original grain remains.

Junmai Daiginjo (純米大吟醸)

The strictest tier. At least half of each grain is polished away — 50% or less remaining — which is why daiginjo has that noticeably lighter, more fragrant character.

Here’s the part that actually surprised me: the more a sake is polished, the more raw rice it takes to make the same bottle. Milling away half a grain to make daiginjo means you need roughly twice as much raw rice as a junmai brewed from a grain that’s barely polished at all, just to end up with the same usable amount of starch. That’s a direct, physical reason daiginjo costs more — it isn’t only marketing, it’s arithmetic. At the brewery, there was a display comparing the three grades side by side, showing what’s left of the same starting grain after each level of polishing — genuinely one of the more interesting five minutes of the whole trip.

One more thing worth knowing before you plan around this trip: if you’re going to taste sake at Niigata Station’s Ponshukan tasting counter (more on that below), the price just changed. As of July 2026, it’s ¥1,000 for five tasting tokens — up from ¥500, the first increase since the counter opened in 1995. Budget for double what older guides and blog posts still say.

This is where the free preview ends. Paid subscribers get the brewery visit, the full station tasting breakdown, where to drink it with food, and the honest downside of a sake-heavy trip.

Getting there is easy: Niigata City is about 1 hour 40 minutes from Tokyo Station on the Joetsu Shinkansen, direct, no transfers.

Niigata is rice country, and in Japan, rice country means sake country, and sake country — on the coast, next to the Sea of Japan — usually means very good fish. Echigo-Yuzawa, on the way in from Tokyo, has some of the best onsen towns in the region. But this post is about Niigata City itself, where I spent most of my time, and where I ate better than I expected to.

This is going to run as three posts. Today is the general “what to do” guide. Next is a full explainer on how Japanese sake is actually made, plus the brewery tour I did and where to drink in the city. After that, paid subscribers get the sushi post — including the one restaurant here that has, at different points, been ranked the number one conveyor-belt sushi restaurant in the country on Tabelog.

If you like rice, seafood, or sake — in roughly that order of enthusiasm — this is your guide.

What Actually Makes Niigata Worth the Trip

Three things, in order of how much they’ll surprise you:

• The rice. Koshihikari rice is grown all over Japan now, but it started here, and the version grown in Niigata’s own soil and water tastes noticeably different from what you’ll get in Tokyo.

• The sake. Niigata has more sake breweries than almost any other prefecture in Japan, because good sake needs the same thing good rice needs — cold water, cold winters, and rice.

• The seafood. The Sado Strait, between Niigata and Sado Island, is a genuinely good fishing ground. What lands here in the morning is often on a plate in the city by lunch.

Eat Real Koshihikari — Not the Export Version

You can buy Koshihikari rice in Tokyo, in Los Angeles, in a supermarket near you. What you can’t easily get outside Niigata is Koshihikari grown here, cooked the way it’s cooked here, and served the same day it was milled.

The easiest way to notice the difference isn’t a formal restaurant — it’s an onigiri (rice ball) shop. A good one will let the rice do the work, with almost nothing added except salt and maybe one simple filling. I’ll point you to my personal favorite in a later post, but for now: if you see a dedicated onigiri-ya near Niigata Station, go in. It’s a five-minute stop that tells you more about why this prefecture is proud of its rice than any museum would.

Sake Country, Twice Over

Because rice is Niigata’s identity, sake is too — a large share of the sake made in Japan starts with rice grown here. I’ll go into how sake is actually made in the next post, but there are two things worth doing while you’re in the city itself:

1. A brewery tour, booked short notice. I visited one and managed to book a slot roughly 30 minutes beforehand — worth asking at your hotel or the tourist information desk if you want to try the same thing, since availability changes day to day.

2. A sake tasting at Niigata Station. Ponshukan (ぽんしゅ館), right inside the station, lets you sample dozens of Niigata sakes side by side. You rent a small cup, pay for a set of tasting tokens, and pour your own from vending-style dispensers — each with tasting notes posted next to it. It’s genuinely fun even if you don’t know anything about sake going in, and I’ll walk through it properly (including current pricing, since it changed this year) in the next post.

The Seafood Is Better Than Tokyo’s

I want to be careful with a claim like that, because “better than Tokyo” gets said about a lot of regional food in Japan and it isn’t always true. Here, I think it holds up — the proximity to the Sado fishing grounds means shorter time between catch and plate.

If you’re a sake person, the natural move is an izakaya that does both well. A few that come recommended locally, in case you get there before I do a full write-up:

• Ebisudai (越後の旬と地酒 えびす鯛) — Google Maps

• Issei Niigata (壱勢 新潟店) — Google Maps

If sake isn’t your thing but sushi is, an authentic sushi counter like Sushiiwa (すしいわ) — Google Maps — is the better fit. And if you want the single most talked-about sushi experience in the prefecture — a restaurant that’s been ranked the number one conveyor-belt sushi chain in Japan on Tabelog — that’s a full post on its own, coming as part three of this series, for paid subscribers.

Don’t Skip the Soba, or the Wagashi

Buckwheat noodles aren’t the first thing people associate with Niigata, but the region has its own style, sometimes called Hegisoba. Suzakaya Soba Niigata Ekimae (須坂屋そば 新潟駅前店) — Google Maps — right by the station, is a reliable, well-regarded spot if you want to try it without hunting.

And before you leave, try sasa dango (笹団子) — a traditional wagashi made of sweet rice dough, filled with red bean paste, and wrapped in a bamboo leaf. It’s the kind of thing that looks like a souvenir and turns out to be genuinely good.

What a Doctor Notices About the Way People Eat Here

I can’t turn this off, so here’s the honest version: this is a diet built almost entirely around fermented and minimally processed foods — sake and miso from fermentation, rice as the caloric base rather than refined flour, and fish eaten close to raw and close to fresh, which preserves the omega-3 fats that get damaged by heavy cooking. None of that makes Niigata a “superfood destination” — it’s just a place where the traditional Japanese diet, the one linked in the research to lower cardiovascular risk, is still closer to how people actually eat day to day.

The Honest Downside

A few things worth knowing before you go, so the trip isn’t more friction than it needs to be:

• Many of the best places — the izakaya, the smaller sushi counters — have little to no English menu. Google Translate’s camera function earns its keep here.

• Cash is still more useful than you’d expect at smaller, older establishments.

• The city itself is compact and walkable near the station, but the best onsen towns (Echigo-Yuzawa) and the fireworks in Nagaoka are separate day trips, not something you’ll fit into one afternoon.

• If sake tasting is part of your plan, you’ll want to not be driving afterward — obvious, but easy to forget when the tasting counter is right there at the station.

Practical Info

Frequently Asked Questions

Is Niigata worth visiting if I only have a few days in Japan? If your priority is food and sake specifically, yes — it’s close enough to Tokyo (about 2 hours by Shinkansen) that it works well as a 1–2 night trip rather than requiring a full separate itinerary.

What’s the best time of year to visit Niigata for food? Autumn, when the new rice and new sake (shinshu) are released, and winter, when cold-water seafood like buri (yellowtail) is at its best.

Do I need to speak Japanese to enjoy Niigata’s food scene? No, but you’ll rely on translation apps more than you would in Tokyo, especially at smaller izakaya and sushi counters.

Is Niigata sake different from sake made elsewhere in Japan? Yes — it tends toward a drier, cleaner style often described locally as tanrei karakuchi. I cover why in the next post.

Can I visit Niigata as a day trip from Tokyo? Yes, technically — the Shinkansen makes it possible — but you’ll get far more out of it with at least one overnight stay, especially if you want to do a sake tasting without rushing.

Is Niigata safe and easy for solo travelers? Yes. It’s a mid-sized Japanese city with the same general safety and infrastructure you’d expect anywhere else in the country.

A Final Word, as a Doctor

I go to a lot of places in Japan for this newsletter, and not all of them earn a three-part series. Niigata did, almost by accident — I went for the rice and the sake, and left thinking more about the fish than either. That’s usually a good sign a place is worth a second visit.

Part 2 is the sake deep dive: how it’s actually made, my brewery tour, and where to drink it properly in the city. Part 3, for paid subscribers, is the sushi restaurant that made me understand why people here take their seafood so seriously.

One of the most common questions I receive from people planning a medical checkup in Japan is surprisingly simple:

“Can a blood test actually detect cancer?”

The answer is:
sometimes, yes.

Not perfectly.
Not definitively.
But in certain situations, tumor marker blood tests can become an important early signal that something deserves further investigation.

And honestly, this is one of the most misunderstood parts of preventive medicine.

If you want to learn more about Japanese medical checkups and ningen dock itself, I wrote a full guide here:
https://www.japanwellnesstravel.com/p/ningen-dock-japan-for-foreigners

Today, though, I want to focus specifically on tumor markers:
what they are, what they detect, what they cannot detect, and why more international visitors are adding them to their Japan medical checkups.

What Are Tumor Markers?

Tumor markers are substances measured in the blood that may increase when certain cancers develop in the body.

Usually these are:
• proteins
• antigens
• enzymes
• hormones

produced either directly by cancer cells or by the body reacting to cancer.

Think of them as:
possible warning signs.

Not proof.
Not diagnosis.
Not certainty.

And this distinction matters enormously.

One of the biggest mistakes people make is assuming:
“normal marker = no cancer”
or
“high marker = definitely cancer.”

Medicine is unfortunately not that simple.

But when interpreted properly alongside imaging and other screening tools, tumor markers can sometimes help identify problems earlier than symptoms appear.

The Tumor Marker Most People Ask About: CA19-9

Pancreatic Cancer Screening in Japan

Among all tumor markers, CA19-9 is probably the one I receive the most questions about.

Why?

Because pancreatic cancer scares people.
And understandably so.

Pancreatic cancer is often difficult to detect early because symptoms may not appear until later stages.

CA19-9 is a marker associated with:
• pancreatic cancer
• bile duct cancer
• gallbladder cancer

In Japan, many people combine:
• CA19-9 blood testing
with:
• abdominal ultrasound
• abdominal CT
• MRI / MRCP

to improve screening accuracy.

But here’s the important part:

CA19-9 is NOT a perfect test.

Some people with pancreatic cancer have normal CA19-9.
And some people without cancer have elevated values due to:
• pancreatitis
• gallstones
• liver disease
• inflammation

This is why good doctors never interpret tumor markers alone.

CEA: One of the Broadest Tumor Markers

CEA is another very commonly requested tumor marker in Japan.

It can become elevated in:
• colorectal cancer
• stomach cancer
• lung cancer
• pancreatic cancer

Because it overlaps across multiple cancers, it’s often included as part of broader preventive screening.

However, there’s something many people do not know:

Smokers can naturally have elevated CEA levels even without cancer.

This is one reason medical interpretation matters.
Numbers alone do not tell the whole story.

AFP: Liver Cancer Screening

AFP (alpha-fetoprotein) is primarily used in liver cancer screening.

This becomes especially important for people with:
• hepatitis B
• hepatitis C
• fatty liver disease
• cirrhosis
• heavy alcohol history

Japan has historically invested heavily in liver disease screening, which is one reason AFP testing is widely available in Japanese preventive healthcare systems.

Usually AFP is paired with:
• abdominal ultrasound
or:
• liver imaging

rather than being used alone.

PSA: The Most Established Tumor Marker for Men

For men over 50, PSA is one of the most important baseline tests to know.

PSA is associated with:

prostate cancer

One thing I often tell patients is:

the trend matters more than one number.

Even if a PSA value falls within “normal range,” a steady rise over several years may still deserve attention.

This is why establishing baseline values early can be extremely valuable.

Many Japanese doctors recommend beginning PSA tracking in your 40s, especially if there is family history.

CA125 & CA15-3

Women’s Tumor Markers in Japan

For women, two markers commonly included in Japanese medical checkups are:

CA125

Associated primarily with:
• ovarian cancer

CA15-3

Associated with:
• breast cancer

But again, context matters enormously.

CA125 may increase during:
• menstruation
• endometriosis
• benign ovarian conditions

which can create anxiety if people interpret results without proper explanation.

This is why I strongly believe:
tumor markers should always be combined with imaging and physician interpretation.

Cyfra & SCC

Lung Cancer and Squamous Cell Screening

These markers are less well-known internationally, but commonly available in Japan.

Cyfra

Associated with:
• non-small-cell lung cancer

SCC

Associated with:
• cervical cancer
• esophageal cancer
• certain lung cancers

These are often added for:
• smokers
• former smokers
• higher-risk patients

especially when combined with low-dose chest CT screening.

The Biggest Misunderstanding About Tumor Markers

As a doctor, this is the part I care about most.

Tumor markers are NOT magic cancer detectors.

Sometimes they detect nothing.
Sometimes they rise for non-cancer reasons.
Sometimes cancers exist despite normal bloodwork.

And yet…

I still believe they can be extremely valuable when used correctly.

Why?

Because preventive medicine is rarely about one perfect test.

It is about building layers of information:
• bloodwork
• imaging
• history
• trends over time
• risk factors

Together, these layers create a much clearer picture of health.

Why Many International Visitors Choose Tumor Marker Testing in Japan

One reason more travelers are interested in tumor marker testing in Japan is accessibility.

In many countries:
• tests require referrals
• costs vary dramatically
• insurance becomes complicated
• preventive testing is difficult to arrange

In Japan, tumor markers can often be added easily to existing medical checkups.

And many visitors combine them with:
• MRI screening
• CT scans
• ultrasound
• endoscopy
• full ningen dock evaluations

during a single trip.

For people already visiting Japan, this can become an opportunity to obtain a level of preventive screening that feels difficult to access at home.

My Honest Opinion as a Japanese Doctor

I do not believe people should live in fear of cancer.

But I also do not believe ignoring health creates peace of mind.

Some of the most heartbreaking patients I encountered during training were not people with untreatable disease.

They were people who simply discovered things too late.

That is why I believe preventive medicine matters.

Not because it guarantees safety.
But because early detection creates options.

And options can change lives.

The Fukugi Tree Tunnel in Bise was not just a scenic walkway — it was a living village landscape wrapped in centuries-old trees, ocean air, and silence so deep that you begin to notice your own thoughts again.

Unlike Tokyo, where everything moves fast and loud even in quiet corners, this place feels almost like the world has pressed pause. Walking here, I remember thinking that this is something I could never experience in the middle of a city like Tokyo — not just visually, but mentally. It is a kind of stillness that does not exist in modern urban life.

The more I walked, the more I realized this is not a “tourist attraction.”
It is a space where nature, memory, and daily life still coexist.

What Is the Fukugi Tree Tunnel in Okinawa?

Located in Bise, Motobu Town in northern Okinawa, the Fukugi Tree Tunnel is one of Japan’s most beautiful surviving traditional village landscapes.

It features:

• Thousands of Fukugi trees (“Fuku-gi,” meaning trees of happiness)

• A green tunnel stretching over 1 kilometer

• Trees planted over 100–300 years ago

• A village still shaped by wind, sea, and nature

• A landscape designed to protect life from typhoons

Unlike planned gardens or modern parks, this is an organic cultural environment — a place where people have lived with nature, not separated from it.

What You Experience at Fukugi Tree Tunnel

The moment you enter the tunnel, the atmosphere changes.

Sunlight filters softly through dense green leaves. The air feels slightly cooler. The sound of footsteps becomes louder than everything else.

There is no rush here.

You can walk, cycle, or simply stop and stand still — and the village continues around you as it always has.

The Feeling of Forest Bathing in Real Life

Without trying, your pace naturally slows down.

This is where many visitors experience what Japan calls shinrin-yoku — forest bathing.

Not as an activity, but as a state of being.

You begin to notice:

• The rhythm of wind moving through leaves

• The contrast between shadow and light

• The absence of artificial sound

• The emotional quiet that follows

It is not dramatic. It is subtle — and that is exactly why it works.

You can read more about shinrin-yoku here.

Recently, I had the chance to talk with Kana — actually, my first real face-to-face conversation online after connecting on Substack (thank you, Substack!).

I had followed her writing for a while and knew she was living in a rural area surrounded by mountains and forests. She writes about making Awa Bancha tea in Kamikatsu, and Kancha tea in a neighbouring village.

But during our conversation, I realized she’s part of something even more special.

She helps run INOW, an impact-driven social travel program based in Zero Waste Kamikatsu, Japan’s first zero-waste village.

And I couldn’t help but share.

Zero Waste Kamikatsu — 45 Categories?!

If you search “Zero Waste Kamikatsu,” you’ll quickly see that this small mountain village in Tokushima declared itself Japan’s first zero-waste town over 20 years ago.

But here’s the part that shocked me.

Residents sort their waste into 45 different categories.

Forty-five.

When I first saw this, I honestly couldn’t believe it. You can actually watch videos of the Zero Waste Center and see how detailed the sorting system is — it’s almost overwhelming at first glance. I was so surprised.

The main place is called the WHY Zero Waste Center, where villagers bring their own trash, wash it, sort it carefully, and take responsibility for it.

Zero waste here doesn’t just mean “good recycling.”

It means aiming to divert 100% of waste from incineration and landfill.

But what’s even more interesting is that for residents, this isn’t a tourist attraction. It’s normal life.

Zero Waste Kamikatsu is deeply connected to the countryside resourcefulness, strong community ties, respect for shared land and water, cultural traditions and intergenerational cooperation.

It’s not a performance. It’s a lifestyle.

How INOW Started in Kamikatsu

Kana’s program, INOW, started in 2020.

INOW was created as an educational social travel program — a bridge between Kamikatsu and the wider world.

Instead of just observing recycling systems, participants:

• Spend time with locals

• Learn about rural life beyond waste

• Reflect on consumption and climate

• Experience community-based learning

• See how sustainability connects to culture

It’s not eco-tourism in a superficial way. It’s slower. More relational.

Forests, Community, and Health

You know how much I love talking about forests.

When I wrote about shinrin-yoku, I shared research showing that simply looking at forests can lower stress hormones by over 13%, and walking in forests can reduce cortisol even more. It also activates the parasympathetic nervous system — our “rest and digest” mode.

Kamikatsu is surrounded by mountains and forests.

But what makes it special is that nature isn’t separate from daily life.

People:

• Clean shared forest water sources

• Farm together

• Plant flowers along the roads

• Gather across generations

And something I’ve personally noticed in rural Japan — the elderly often seem more lively, engaged, and expressive than in urban settings. There’s a kind of spark in them. They are active participants in their community, not isolated.

That kind of social engagement is incredibly important for long-term health and emotional well-being.

Kana’s Story — From City to Village

Kana originally came to Kamikatsu curious about Japan’s first zero-waste village.

She planned to stay a couple of months.

She stayed for years.

What struck me most when we talked wasn’t just sustainability — it was friendship.

She started a business with her partner.

In cities, it’s easy to float anonymously. In villages, relationships are unavoidable. You interact with people in their 60s, 70s, 80s. You see them at community cleanups. You share vegetables. You talk even when your worldviews differ.

Kana wrote that being in Kamikatsu taught her that belonging requires sacrifice, negotiation, and openness to being changed by others.

I found that incredibly honest.

And honestly, I think it’s amazing.

You can read more about her story here.

In Search for Belonging

It’s approaching the end of January, which means we’re finally remembering to write 2026 instead of 2025! I’ve already made this mistake a handful of times, and each time I realize my slip-up, I smile because the new year hasn’t quite settled in. If you're still finding your footing in the new year, I’m with you…

I haven’t visited Kamikatsu yet.

But after speaking with Kana, I really want to.

If you’re already interested in nature in Japan, or if reading about shinrin-yoku made you want to breathe forest air, maybe Zero Waste Kamikatsu will speak to you too.

And if any of you ever join the INOW program, please tell me how it was. I genuinely want to know.

Sometimes the most meaningful travel experiences aren’t about seeing more.

They’re about belonging somewhere, even briefly.

I have visited many places across Japan through my work in wellness travel Japan.

Kyoto’s bamboo forests, Hokkaido’s onsen towns, and Tokyo’s preventive health centers each offer something meaningful in their own way.

But the Valley of Gangala in Okinawa feels a little different.

The moment I stepped inside, the atmosphere felt noticeably quieter and more enclosed, as if the forest had its own rhythm.

What Is the Valley of Gangala?

The Valley of Gangala (ガンガラーの谷) is one of Okinawa’s most extraordinary natural and archaeological sites.

It was formed over 200,000 years ago when a limestone cave collapsed, creating a vast subtropical forest ecosystem spanning approximately 45,000 square meters.

But this is not just a nature walk.

It is also one of the most important prehistoric human sites in East Asia.

Key historical facts:

• Evidence of human life dating back over 20,000 years

• Discovery site of Minatogawa Man (one of Japan’s earliest human ancestors)

• Home to one of the world’s oldest fish hooks (23,000 years old)

• Active archaeological research continues today

This combination of ancient human history + untouched subtropical nature makes it one of the most unique mindful travel Japan experiences.

Why Travelers Experience Deep Reset Here

From a medical and physiological perspective, places like Gangala Valley activate what we call the parasympathetic nervous system — the body’s rest-and-repair state.

Research on forest bathing (shinrin-yoku) shows:

• Reduced cortisol (stress hormone)

• Improved immune response

• Lower blood pressure

• Enhanced emotional regulation

When people hear “health checkup,” they often imagine a quick blood test or a short doctor visit.

But in Japan, there’s a system called Ningen Dock—a comprehensive, full-body screening designed to detect diseases early and understand your health before symptoms appear.

So what do you actually learn from it?

1. What You Can Learn from a Ningen Dock

A Ningen Dock gives you a complete picture of your body, not just one aspect.

It typically includes:

• Body composition (weight, BMI, visceral fat)

• Blood tests (cholesterol, liver, kidney, glucose)

• Heart and lung function (ECG, X-ray, breathing test)

• Urine and stool analysis

• Imaging (CT, ultrasound)

• Eye and hearing tests

• Infection and inflammation markers

What’s unique is that everything is combined into one report, and instead of just numbers, you also get clear judgments and recommendations.

Example of What the Results Look Like

Here is an example of the type of report you receive:

• Each category (blood, liver, heart, etc.) is graded (A–G)

• You see both your actual values and the reference range

• Doctors include comments and next steps

At first glance, it can look overwhelming—but once you understand how to read it, it becomes incredibly insightful.

Also, at MEDICAL CHECKUP JAPAN CONCIERGE, we hand out the English translation to you.

2. What the Tests Actually Mean (Partly Explained)

Instead of just listing numbers, here’s how to actually think about them:

🩺 Body Composition & Metabolic Health

• BMI (Body Mass Index) → a rough indicator of weight balance

  • Around 22 is considered ideal in Japan

  • 25+ suggests increased metabolic risk

• Waist circumference / visceral fat
  → more important than weight alone
  → directly linked to diabetes and cardiovascular disease

👉 Even if your weight looks “normal,” internal fat can tell a different story.

🩸 Cholesterol & Lipids (Heart Health)

• LDL (bad cholesterol) → builds up in blood vessels

• HDL (good cholesterol) → helps remove excess cholesterol

👉 High LDL over time increases risk of:

• Heart attack

• Stroke

• Atherosclerosis

But what’s important is:

It’s not just “good or bad”—it’s about long-term trends.

🍬 Blood Sugar & Metabolism

• Glucose → your current blood sugar

• HbA1c → your average blood sugar over the past 1–2 months

👉 These help detect:

• Prediabetes

• Diabetes risk

🚽 Urine & Stool Tests

• Urine → kidney function, hydration, metabolic balance

• Stool (occult blood test) → detects tiny amounts of blood you can’t see

👉 This is especially important for:

• Early detection of colon issues

• Cancer screening

👁 Vision (How to Read the Numbers)

Vision is measured as a decimal:

• 1.0 = standard “normal” vision

• 0.5–0.7 = mild reduction

• <0.3 = more significant impairment

👉 So if you’re at 0.5–0.6, it means:

• You can still function normally

• But your vision is not fully sharp

I’ll be breaking down more of these individual markers in future newsletters—including how to interpret them and what to actually do with the results—so feel free to subscribe if you’d like to go deeper.

3. What I Personally Learned from My Checkup

I recently did Ningen Dock in my mid-20s.

Overall, I was healthy—but the details were the most valuable part.

Cholesterol — “normal” but not optimal

My total cholesterol:

• Reference: 140–199 mg/dL

• Mine: 186 mg/dL (A judgment)

So yes—completely normal.

But at the same time, it’s closer to the higher end.

My LDL:

• Reference: 60–119 mg/dL

• Mine: 95 mg/dL

Again, normal—but I’d still like to optimize it further.

👉 That’s the key mindset shift:
Even within “normal,” there’s room to improve.

Vision — something I knew, but needed to address

I already had a feeling my vision wasn’t great—and the test confirmed it.

My results were:

• 0.6 and 0.5 (with contact lenses)

Which means:

• I can function fine in daily life

• But my vision isn’t fully sharp or optimal

Seeing it clearly quantified made me realize:

This isn’t just something to “live with”—it’s something I should properly correct.

In my case, it made me think about updating my glasses or contact lenses, rather than continuing with something that isn’t giving me full clarity.

🧪 Amylase — a subtle signal

My amylase level was slightly elevated.

Right now, I have no symptoms—but the recommendation was:

If you develop abdominal pain, follow up with a doctor.

👉 What stood out to me:
Even small findings are not dismissed—they’re tracked and contextualized.

Final Takeaway

What makes Ningen Dock powerful isn’t just the number of tests.

It’s how everything is connected:

• Data → Interpretation → Action

Even as someone young and healthy, I came away with:

• A clearer understanding of my body

• Small but important areas to improve

• A more proactive approach to health

If you’re searching for the best Okinawa soba in Naha, a hidden local restaurant near Naha Airport, or an authentic Japanese noodle experience, this is exactly the kind of place you’re hoping to find—but rarely do.

I was in Okinawa last month with my friend, and on our way to Naha Airport, we casually searched Google Maps for a great soba spot. No expectations—just something local.

What we found turned out to be one of the best Okinawa soba experiences in Japan.

A Traditional Okinawan Home You Can Dine In

The moment you step inside, it doesn’t feel like a restaurant.

It feels like stepping into a traditional Okinawan house.

The warm wooden interior, tatami flooring, and low tables immediately slow you down. You’re not just eating—you’re settling into the space.

Every detail adds depth to the experience:

• Handwritten calligraphy hanging naturally on the wall

• Traditional pottery and shelves that feel personal, not decorative

• Soft lighting reflecting off aged wood

• Tatami seating that creates a calm, grounded atmosphere

Nothing feels designed for tourists.

Instead, it feels real, local, and lived-in—like you’ve been quietly welcomed into someone’s home.

Wide Variety of Okinawa Soba (Perfect for First-Time Visitors)

Another reason this stands out as one of the best soba restaurants in Okinawa is the variety.

You’ll find:

• Multiple Okinawa soba styles

• Different broths and noodle textures

• A wide range of traditional toppings

If you want to know the exact restaurant name and what I personally ordered (including the best-value set to choose), continue reading below — this is where you unlock the full experience.

It was during my hospital rotation — my forth year of medical school — when I met Mr. T. He was 58 years old, a company executive who had been “too busy” for checkups his whole life. He came in because his back had been hurting for a few weeks.

The imaging results shook me to my core: Stage IV colon cancer. He had maybe six months.

What haunted me wasn’t the diagnosis itself. It was what the attending physician said afterward, almost to himself:

“If he’d done a ningen dock five years ago, we might have caught this.”

That sentence has never left me.

I’ve been practicing medicine in Japan for years now, and I can tell you — the number of patients I see who arrive too late is heartbreaking. Advanced cancers. Severe cardiovascular disease. Strokes that didn’t need to happen. And in almost every single case, I find myself thinking: this could have been caught earlier.

Japan has a system specifically designed to prevent this tragedy. It’s called ningen dock, and it is, without exaggeration, one of the most extraordinary preventive healthcare tools in the world.

The shocking part? Most foreigners have never heard of it.

Until now.

What Is Ningen Dock? Japan’s Revolutionary Full-Body Health Checkup Explained

Subscribe now

Ningen dock (人間ドック, pronounced “nee-gen doc-ku”) literally translates to “Human Dock.” The name is inspired by the concept of a ship dock — where a vessel goes in for a thorough inspection and maintenance check before heading back out to sea.

The analogy is perfect. Your body is the ship. Ningen dock is the inspection.

Developed in Japan in 1954 at the National Tokyo Daiichi Hospital, ningen dock was born out of a national health crisis: Japan was seeing surging rates of chronic illness, cancer, and cardiovascular disease. Rather than simply treating disease after it appeared, Japanese healthcare leaders made a bold decision — catch it before it starts.

Seventy years later, that decision has helped make Japan the country with one of the highest life expectancies on Earth: 84 years on average, approximately 6 years longer than the global average. PMC - National Center for Biotechnology Information

Today, ningen dock is offered at 1,727 facilities across Japan and involves approximately 3.7 million people annually. It is not just a medical service — it is a cultural institution. PMC

Why I Think Every Foreign Visitor to Japan Should Consider This

In the United States, a comparable battery of tests — if you could even find a clinic that offered them together — would run you way more, assuming your insurance didn’t fight you at every step. In Canada, you might wait 6 to 12 months just to get individual tests referred through your GP. In many other countries, several of these tests simply aren’t available to the general public at all.

In Japan, you show up for half a day. You leave with a complete picture of your health, explained to you by a doctor, in a clean, calm, state-of-the-art facility.

Growing up in Japan, I genuinely thought this was normal. It was only when I started communicating with foreign friends and colleagues that I realized: this is not normal. This is extraordinary.

Everything That’s Included in a Ningen Dock: The Full Breakdown

One of the most common questions I receive is: “But what exactly do they test?”

The answer is: a lot. Far more than most people expect. Here is a comprehensive overview of what a standard ningen dock package covers, along with optional add-ons:

🩸 Blood Analysis — Your Body’s Chemical Story

• Complete Blood Count (WBC, RBC, hemoglobin, hematocrit, platelets)

• Liver function (AST, ALT, γ-GTP, ALP, bilirubin, albumin)

• Kidney function (creatinine, urea nitrogen, electrolytes)

• Lipid panel (total cholesterol, HDL, LDL, triglycerides)

• Blood sugar & HbA1c (diabetes screening)

• Uric acid (gout)

• Thyroid hormones (TSH, FT4)

• Tumor markers (PSA for prostate, CA-125 for ovaries, CEA for colon/lung)

• Hepatitis B & C, syphilis serology

🫀 Heart & Cardiovascular System

• Resting ECG (electrocardiogram)

• Stress ECG — detects circulation problems that don’t appear at rest

• Echocardiogram (cardiac ultrasound — checks heart structure and valves)

• Carotid artery ultrasound — measures vessel wall thickness, detects early hardening

• Ankle-arm blood pressure index (ABI) — screens for peripheral artery disease

🧠 Brain & Neurological

• Brain MRI — detects silent strokes, tumors, early abnormalities

• Brain MRA (magnetic resonance angiography) — images blood vessels, detects aneurysms

🫁 Chest & Lungs

• Chest X-ray

• Chest CT scan (especially recommended for ages 40+)

• Pulmonary function test — detects asthma, COPD, early lung disease

🍽️ Digestive System — Where Cancer Hides

• Upper endoscopy (esophagus, stomach, upper small intestine) — looks for ulcers, H. pylori infection, early gastric cancer

• Colonoscopy — full colon examination; polyps can be removed during the procedure

• Abdominal ultrasound (liver, gallbladder, kidneys, spleen, pancreas)

• MRCP (MRI of bile ducts and pancreas) — for suspected blockages

👁️ Sensory Evaluations

• Vision acuity and intraocular pressure (glaucoma screening)

• Hearing test

• Ocular fundus examination (detects hypertensive and diabetic eye changes)

💧 Urine & Stool Analysis

• Urine: specific gravity, pH, protein, glucose, occult blood, sediment, microalbumin

• Stool: fecal occult blood (colorectal cancer screening)

👩 Women’s Health

• Mammogram (ages 40+) or breast ultrasound (under 40)

• Breast MRI for high-risk or dense breast tissue

• Pap smear (cervical cancer screening)

• Transvaginal ultrasound (uterus and ovaries)

• Bone density measurement (osteoporosis screening)

⚙️ Optional Advanced Tests

• Full-body MRI (head to pelvis — all organs in one scan)

• PET-CT scan (whole-body cancer detection)

• Genetic risk analysis

• H. pylori breath test

• HPV testing

As a doctor, I want to be honest with you: this is not a basic checkup. This is a diagnostic deep-dive that most people in most countries will never experience. And that is exactly why I think foreign visitors to Japan are missing a once-in-a-lifetime opportunity.

The Diseases Ningen Dock Can Catch — Before You Even Feel Them

This is the part that matters most to me as a physician.

The diseases that kill the most people globally — cancer, heart disease, stroke, diabetes — are almost universally silent in their early stages. By the time you feel them, treatment is often exponentially harder and more expensive.

Here is what ningen dock is specifically designed to detect early:

This table tells a story I’ve seen play out in real patients, real families. Every one of those diseases is far more treatable — and far less devastating — when caught at the beginning.

Japan’s Longevity Secret — And Why Ningen Dock Is Central to It

People often ask: Why do Japanese people live so long?

Diet is part of it. Lifestyle is part of it. Social connectedness is part of it.

But as a physician, I believe early detection through regular health screening is one of the most underappreciated factors.

Japan’s life expectancy stands at 84 years — one of the highest in the world, approximately 6 years longer than the US average.

Japan has extremely high rates of cancer detection in early stages compared to most countries, particularly for gastric, colorectal, and lung cancers. This is directly attributable to widespread ningen dock participation.

When you invest in knowing your health, you make better decisions. You treat things early. You prevent the cascade of complications that turns a manageable condition into a life-altering one.

Ningen dock isn’t just a health checkup. It’s a philosophy — the philosophy that your future self deserves the same care as your present self.

The Honest Challenges Foreign Visitors Face — And How to Overcome Them

I want to be transparent with you, because I think you deserve honesty rather than a sales pitch.

Accessing ningen dock as a non-Japanese speaker is not seamless — at least not if you try to do it alone. Here are the real barriers I hear from foreign visitors:

🚧 Challenge 1: Language

Many facilities operate entirely in Japanese. Forms, instructions, results, phone calls — all in Japanese. Medical Japanese is not conversational Japanese. Even fluent Japanese speakers struggle with clinical terminology.

A mistranslation of your medical history or current medications isn’t just inconvenient — it can genuinely affect your screening results and the recommendations you receive.

🚧 Challenge 2: Understanding Results

Your report will likely be in Japanese, filled with medical terminology and Japanese reference ranges that differ from what you’re used to. Without guidance, an “abnormal” finding might cause panic unnecessarily — or a concerning finding might be overlooked.

🚧 Challenge 3: Choosing the Right Package

With dozens of facilities offering different packages at varying price points, choosing the right one for your specific health profile requires genuine medical knowledge. A 35-year-old woman with a family history of breast cancer has entirely different needs than a 55-year-old man with a history of smoking.

✅ The Solution

This is precisely why services like MEDICAL CHECKUP JAPAN CONCIERGE exist — to make ningen dock fully accessible to international visitors, with zero stress and complete confidence.

How Medical Checkup Japan Concierge Helps You Every Step of the Way

I want to introduce you to the service I personally recommend for foreign visitors who want to experience ningen dock.

MEDICAL CHECKUP JAPAN CONCIERGE was created specifically to bridge the gap between world-class Japanese healthcare and the international visitors who deserve access to it.

Here’s what we do for you:

🩺 Step 1: Personalized Pre-Consultation (Free)

Before anything is booked, a medical professional sits down with you (virtually or in-person) to discuss:

• Your health history and concerns

• Family medical history

• Current medications and conditions

• Your goals for the checkup

Based on this, they recommend the specific facility and package that best matches your profile. Not a one-size-fits-all recommendation — a genuinely personalized one.

📅 Step 2: Complete Booking Coordination

They handle every single aspect of the booking:

• Priority appointment access — even during peak seasons

• All communication with the hospital in Japanese

• Pre-exam instructions translated into English

• Dietary and medication protocols clearly explained

🏥 Step 3: Day-of-Exam Support

On the day of your checkup:

• A bilingual medical interpreter accompanies you throughout

• All paperwork and check-in handled for you

• Real-time explanation of each test as it happens

• Immediate translation of any findings or doctor’s comments

• Cultural and logistical navigation so you focus only on your health

📋 Step 4: Results Translation & Consultation

Once your results are ready:

• Full English translation of your medical report

• One-on-one consultation (video or phone) to walk through every finding

• Explanation of Japanese reference ranges vs. international standards

• Personalized health recommendations based on results

• Coordination of any necessary follow-up — whether in Japan or with your home physician

🌏 Why This Matters

As a doctor, what I value most about this service is the last step. A health report is only useful if you understand it. I’ve seen too many people receive their results, fail to understand the nuances, and return home without acting on findings that warranted attention. Having a medical professional walk you through your results isn’t a luxury — it’s essential.

What Real Patients Say About Ningen Dock

Sometimes the most powerful evidence isn’t medical research — it’s real human experience.

Frequently Asked Questions About Ningen Dock for Foreign Travelers

Q: Can foreigners get a ningen dock in Japan? Yes, absolutely. Many facilities in Japan accept international patients. However, most require Japanese-language coordination, which is why using a concierge service is strongly recommended.

Q: How long does a ningen dock take? Most packages are completed in 3–5 hours as a half-day experience. Two-day comprehensive packages are also available.

Q: Do I need to fast before ningen dock? Yes. Most packages require fasting from the night before (typically no food or water after midnight). Your concierge will provide specific instructions.

Q: What language will my results be in? Results are typically provided in Japanese. With Medical Checkup Japan Concierge, you receive a full English translation and a one-on-one explanation.

Q: Is ningen dock covered by travel insurance? Ningen dock is a preventive health screening, not a treatment, so it’s typically not covered by standard travel insurance. However, some international health insurance plans may cover a portion. It’s worth checking with your insurer.

Q: Can I get ningen dock on a tourist visa? Yes. There are no restrictions based on visa type. Any visitor to Japan can access ningen dock.

Q: How far in advance should I book? Popular facilities in Tokyo and Osaka can be booked out 1–3 months in advance, especially during peak travel seasons. Book as early as possible, ideally 4–6 weeks before your trip.

Q: Is it safe? Are there any risks? Ningen dock is primarily diagnostic — meaning the tests are designed to detect, not treat. The most “invasive” element is typically the endoscopy, which is performed by experienced gastroenterologists and carries minimal risk.

How to Include Ningen Dock in Your Japan Trip: A Practical Timeline

Many visitors to Japan don’t realize that ningen dock can be seamlessly woven into a normal travel itinerary. Here’s how I recommend planning it:

6–8 weeks before your trip: → Contact MEDICAL CHECKUP JAPAN CONCIERGE for your free health consultation → Decide on your package and preferred facility (Tokyo, Osaka, Kyoto) → Confirm your appointment date

1–2 weeks before your checkup: → Review pre-exam instructions (fasting, medication restrictions) → Prepare your medical history summary in English → Confirm transport and logistics with your concierge

Day of your checkup: → Arrive at the facility with your concierge/interpreter → Complete 3–5 hours of comprehensive screening → Receive same-day results consultation with your doctor

After your checkup: → Receive full English results report within a few days → Schedule a results consultation with your MEDICAL CHECKUP JAPAN CONCIERGE advisor

A Final Word From Me, as a Doctor

I write this not as a marketer, but as a physician who has watched too many people receive diagnoses that came too late.

The patients who haunt me most aren’t the ones with rare diseases or tragic accidents. They’re the ones who had entirely preventable, entirely detectable conditions — who simply didn’t know, because nobody had looked.

Ningen dock changed how I think about healthcare. Growing up in Japan, I took it for granted. Now I understand it is one of the greatest gifts a health system can offer: the gift of knowing.

If you are traveling to Japan — whether for a week or a year — I genuinely encourage you to consider dedicating half a day to ningen dock. Not because something is wrong. But because knowing what’s right is exactly as important.

Your future self will thank you.

A Quick Note — Save the Date

If you (or someone you know) will be in Tokyo on May 2nd, I have something special planned.

I’ll be hosting a very limited, in-person event where you can experience Japanese preventive healthcare firsthand—including the opportunity to participate in a guided medical checkup in a real clinic setting.

👉 Early registration link (limited access):

Thank you so much to everyone who read my last post about Katsuoji-temple. Since I recently took a medical exam in Japan, I found myself thinking a lot about “願掛け” (making wishes before big moments).

So today, I want to share something a little different—but very connected.

This post is for:

• Those looking for a great unaju spot in Osaka/Hyogo

• Anyone who has an exam, competition, or important life event coming up

• And those curious about the deeper meaning behind Japanese food culture

What Is Unaju—and Why Do Japanese People Eat It Before Big Moments?

If you’ve ever searched what Japanese people eat before exams or important days, this is something you might not see often—but it’s very real.

Unaju (うな重) is grilled eel (unagi) served over rice in a lacquered box, glazed with a sweet soy-based sauce.

But beyond the taste, there’s a cultural meaning.

In Japan, unagi is associated with stamina, focus, and resilience. Some even say it’s connected to wisdom (知恵の神様の使い), which is why people eat it before:

• Exams

• Important work presentations

• Sports competitions

• Big life moments

From a medical perspective, it’s also interesting.

Unagi is rich in:

• Vitamin A

• Vitamin B complex

• Omega-3 fatty acids

So while it’s not a “magic food,” it’s definitely one of the most nutrient-dense traditional dishes.

My Go-To Spot: Unatomi

Today, I want to share my personal favorite place for unaju: Unatomi.

It’s actually a local chain with multiple locations in Osaka and Hyogo (Takarazuka, Sanda, Takatsuki, Ikeda, Kawanishi, Minoh), which makes it very accessible.

What I like about it is that it doesn’t feel like a tourist place at all. Most customers are Japanese locals, and many come for special occasions or family meals.

It’s not cheap—but for the quality, I think it’s absolutely worth it.

Why Unatomi Stands Out

1. Carefully Selected Japanese Eel

They use only domestic Japanese eel (ニホンウナギ), delivered fresh every morning. The eel is raised in clean groundwater and fed carefully to preserve its natural fat and texture.

When you take a bite, it’s incredibly soft—almost melting apart.

2. Kansai-Style Grilling (No Steaming)

Do you know the tallest mountain in Japan?
It’s Mount Fuji.

There are many beautiful places to see Mount Fuji, but personally, I think the best view is from the top of the Fujiyama roller coaster at Fuji-Q Highland — right at the moment when the ride slowly climbs the world’s longest uphill track.

When you are going up, Mount Fuji appears right in front of you. The mountain feels close, wide, and powerful. It’s one of those views that stays in your memory.

This post is for you if:

• You want to see Mount Fuji from a unique viewpoint

• You love scary roller coasters and thrilling rides

• You’re traveling with kids who want to enjoy an amusement park

Fuji-Q Highland is very popular in Japan, but for many international travelers, it is still less familiar than Tokyo Disneyland or Universal Studios Japan. One of the best things about Fuji-Q Highland is that you can reach it from Tokyo in about 2 to 2.5 hours, making it a realistic and exciting day trip.

I visited Fuji-Q Highland last month on a Tuesday, and it was such a great experience that I wanted to share it with you.

Famous Guinness World Records at Fuji-Q Highland

Fuji-Q Highland has held many Guinness World Records over the years, especially for its roller coasters. This is one of the reasons thrill-seekers from around the world search for Fuji-Q Highland when planning a trip to Japan.

Some well-known records and attractions include:

• Fujiyama (1996): Certified for world-class height, elevation difference, and speed

  

• Eejanaika (2006): Famous for having one of the highest numbers of spins in the world

• Takabisha (2011): Known for having one of the steepest drops in the world at 121 degrees

• Super Scary Labyrinth of Fear: Known as one of the longest-running haunted houses

Even if you don’t ride every attraction, walking through Fuji-Q Highland feels like being inside the history of extreme roller coasters in Japan.

From here, I’ll be writing about the practical travel tips (how to get to Fuji-Q Highland from Tokyo, best tickets to buy, how to avoid long lines, and how to combine Fuji-Q with Kawaguchiko).

Katsuo-ji Temple is located in the mountains of Minoh, north of central Osaka. The access is easy, but knowing the best route saves time and energy.

Recommended route (easy for most travelers):

• Take the Midosuji Line from Umeda, Shinsaibashi, or Namba

• Get off at Minoo-Kayano Station

• From Minoo-Kayano, go to Katsuo-ji by bus or taxi

From Minoo-Kayano Station to Katsuo-ji:

• Bus:

  • About 20 minutes

  • Around 800 yen one way

  • Best for solo travelers or couples

• Taxi:

  • About 15–20 minutes

  • Often cheaper if you are 3–4 people

  • Comfortable in bad weather or when tired

Why this route is good:

• The Midosuji Line is the main subway line in Osaka

• Transfers are simple for tourists

• The scenery changes from city to mountains, which already feels refreshing

What to eat before Katsuo-ji (best food near Minoh-Kayano / Q’s Mall Recommendation)

You will walk a lot at Katsuo-ji. There are slopes, stairs, and long paths, so eating before you go is important. There is limited food inside the temple area.

Here are my real recommendations near Minoo-Kayano / Q’s Mall:

1) Sushi 北海素材 (Hokkai Sozai)

• A little nicer than typical conveyor belt sushi

• Slightly more expensive, but very good quality

• Perfect if you want a satisfying but not too heavy meal

• Good balance of protein and energy before walking

That place was Katsuo-ji Temple, a temple in the mountains of Osaka.

In Japanese, katsu (勝) means “to win,” and Katsuo-ji has long been known as a place people visit before important moments — exams, competitions, career changes, health challenges.

To be honest, my New Year didn’t feel like a new beginning at all.
That exam was heavy. My head was full.
So I went to Katsuo-ji quietly and made a promise to myself to face the exam properly.

Why People Visit Katsuo-ji Before Exams and Big Moments

Katsuo-ji was founded in the 8th century and has been called a “temple of victory” for centuries.
Warriors once came here before battles.
Today, people come here before:

• Entrance exams

• Job interviews and career decisions

• Business challenges

• Sports competitions

It’s not about wishing for luck without effort.
Katsuo-ji is about making a personal commitment to do your best — even when you’re scared.

That’s why this place feels meaningful for travelers too.
If you’re visiting Osaka and have something important coming up in your life, this is a powerful stop to add to your Japan trip.

Daruma Everywhere — And What They Mean

Katsuo-ji is famous for its Daruma dolls.
Daruma represent persistence and not giving up on yourself.

Here, Daruma are not “magic wish dolls.”
When you write your goal and fill in one eye, you’re making a promise to yourself to face your weakness and not run away.

I did a Daruma-Mikuji, where you choose a Daruma while focusing on one question.
Inside is guidance based on old philosophy, not simple “good luck / bad luck.”

After reading mine, I placed my Daruma on the temple grounds.
They’re everywhere — on rocks, near small altars, quietly watching people walk by.
It’s strangely comforting to see how many people are trying hard at something.

Omamori, Small Comforts, and Daruma Snacks

I also bought an omamori (protective charm) for my exam.
I keep it in my bag now — not because I think it changes results, but because it reminds me of the promise I made to myself that day.

And yes, I ate Daruma-shaped baby castella.
It sounds small, but moments like this make Japanese temples feel warm and human — serious wishes mixed with gentle joy.

If you’re in Osaka and you or someone you love has an exam coming up, I really recommend visiting Katsuo-ji.

And please… wish me luck for passing the exam too! I truly hope I passed.

Last week, I visited a lovely café in central Tokyo with a friend I first met about four years ago.
We’ve only met face to face around three times, but every time we do, the conversation feels natural and easy, as if we’ve known each other for much longer.

Since we both studied outside Japan for university, so meeting in person always feels a little special. This time, we chose a small café in Tokyo called Tokyo Little House. It was my first visit, and I was surprised by how calm and welcoming the space felt from the moment I walked in.

Tokyo has countless cafés, but finding a quiet café in central Tokyo that isn’t crowded can be surprisingly difficult. Tokyo Little House felt like a place where time slows down. The café is not large, but not too small either, and the atmosphere is warm and relaxed. It has a subtle Japanese style, simple but thoughtful, and the overall mood made it easy to settle in and enjoy the moment.

What Makes Tokyo Little House Feel Special

Tokyo Little House stands out among cafés in Tokyo because of its peaceful atmosphere and attention to small details.

Inside the café, you’ll find old maps of Tokyo displayed on the walls and vintage Tokyo magazines.

Seeing these old materials made the café feel like a small time capsule of the city. The name of the place has also remained unchanged for many years, which adds to the feeling that this café has quietly existed alongside modern Tokyo.

Another thing I noticed was the kindness of the staff. There were non-Japanese travelers visiting while we were there. Even when the language was not perfect, the staff explained the coffee in English with patience and a warm smile. That simple, friendly communication made the café feel welcoming.

Located in the refined district of Ginza, Head Spa ZEN offers a fully private, Zen-based head spa experience focused on sensory balance and autonomic nervous system regulation. It is not simply a beauty salon. It is structured as a guided reset for people experiencing digital fatigue, travel stress, and mental overload.

What Makes This Head Spa Different in Wellness Travel Japan?

Many people searching “best head spa Tokyo” or “wellness travel Japan experiences” want something authentic, calming, and culturally rooted.

Head Spa ZEN is built around:

• Zen philosophy and sensory harmony

• Fully private treatment rooms in Ginza

• Guided breathing and meditation

• Alternating pressure and temperature techniques

• Fascia and deep muscle work rarely found in standard salons

The concept centers on restoring breathing patterns disrupted by constant screen exposure and overstimulation. From a Japanese medical background, I find this focus on autonomic balance particularly meaningful. Stress regulation directly affects sleep quality, scalp health, and muscular tension.

If you are planning wellness travel Japan, this is a refined option that fits easily into a Tokyo schedule without leaving the city.

The 90-Minute ZEN (SHIN) Deep Course: Step-by-Step Experience

For readers who want to know exactly what to expect, here is the full structure of the 90-minute session.

ZEN (SHIN) – Deep
¥16,000 (¥17,600 including tax)

This course is designed to unravel mental tension and guide you into deeper clarity.

01 Welcome Drink

You begin with a warm welcome drink in a private room. The transition from Ginza’s busy streets to a quiet interior happens immediately. The lighting is soft and intentionally minimal.

02 Counseling

A short consultation covers scalp condition, stress level, sleep patterns, and preferences. This ensures the pressure and focus areas are customized.

03 Meditation and Breathing

Before any physical treatment begins, you are guided through gentle breathing. This step is central to the philosophy. The goal is to shift from sympathetic to parasympathetic dominance.

04 Aroma Selection

You choose a fragrance that supports relaxation. Scent is one of the fastest ways to influence the nervous system, and the aroma sets the tone for the rest of the session.

05 Scalp Cleansing

The scalp is carefully cleansed to remove buildup and improve circulation. This step supports both hair health and relaxation.

06 Head Immersion

Warm water flows steadily over the scalp. The sound is subtle and rhythmic, similar to shishiodoshi in a Japanese garden. Many guests describe this as the most calming moment.

07 Massage Shampoo – Pressure

A structured massage shampoo applies rhythmic pressure to stimulate circulation and release tension in the scalp.

08 Treatment Massage – Relief

The technique shifts to relief-focused strokes, easing tightness in the scalp, temples, and upper neck.
