A first onsen visit runs on the same short sequence almost anywhere in Japan: undress completely, get clean sitting down beside the bath, soak with your towel and your hair out of the water, then dry off before you step back into the changing room. That part barely varies. Tanabe City’s tourism bureau sets out the same four steps and then adds the caveat that matters — most places follow them, some differ slightly.
Most onsen etiquette is stable enough to learn once. The onsen rules that actually ruin a first visit are the ones no general guide can answer for you: whether that particular bath admits tattoos, whether it counts an approved bathing garment as clothing, whether towels are included or sold at the counter, whether the washing area has showers at all. Each one is set by the facility, each one can change, and each one has an answer you can get before you go. Four questions cover almost all of it, and they fit in a single email.
Before Your First Onsen: Check Tattoos, Bath Options and What to Bring
Hakone Kowakien Yunessun publishes three different answers to the question “can I bathe here with a tattoo?”, and all three are correct, because they apply to three different parts of the same building. Its published FAQ says that as a general rule it does not admit guests with tattoos; that you may use its swimsuit area if you cover them with a rash guard; and that you may use its Mori no Yu bathing area only if they are completely covered with two tattoo cover stickers, with its eight private baths as the fallback if they cannot be. That is not an unusually complicated facility. That is what “check the policy” looks like once you check a real one.
Everything in this section was read on each facility’s own pages in September 2026, and every condition below is set by the individual bath rather than by any nationwide rule, so confirm your own case with the facility itself before you book anything.
Start with which bath you are actually going to use, because every other answer depends on it. A communal bath is the default: shared water, single sex, no clothing. A private bath — you will see it called kashikiri, meaning reserved for your exclusive use — is a room you book by the hour, and Japan’s national tourism organisation treats it as a genuinely different participation option rather than a consolation prize. A swimsuit area is a third thing again, and it is not interchangeable with either: Hakone Yuryo’s visitors’ guide states flatly that bathing in swimsuits is not allowed at its baths, while Yunessun runs a swimsuit area as a separate ticketed zone from its nude bathing area. Two facilities, an hour apart, opposite answers — both published, both current.
That is why a tattoo answer only means something when it is attached to a specific bath. Hakone Yuryo removed its tattoo restriction outright from 1 April 2025, so there is nothing to cover and nothing to ask. Yunessun’s answer depends on which of its zones you buy a ticket for. And covering up is not a universal key: in a widely-read r/JapanTravelTips thread posted in 2025 by someone living in Japan, one respondent noted that some onsen specifically prohibit stickers used to cover tattoos, and the original poster described a friend with full arm, leg and back tattoos — all hidden under clothing — being turned away and made to wait outside. The mechanism is simple enough: the facility, not the tattoo, decides, and a facility that has written “no tattoos, no exceptions” into its house rules has also decided what a sticker counts as.
The publisher of this guide is a travel agency and sells trips, so take the next sentence as coming from an interested party: for a question about your own tattoo, contacting the bath directly is still the better route, because the person who answers the email is the person who applies the rule at the door.
Then there is the quiet one, which is what the ticket actually buys you. General guides tend to say towels are “often available for rent,” which is true and useless. Hakone Yuryo’s FAQ states that it does not rent towels at all — you buy them at reception, at 550 JPY for a bath towel and 300 JPY for a face towel, checked September 2026 — and separately lists face towels and bath towels among the amenities included free with its private open-air baths. Same building, same day: buy your towel for the public bath, get one handed to you in the private one. Yunessun rents rather than sells, at 250 JPY and 150 JPY, and states that admission includes admission only. Soap and shampoo are a different story and usually are provided at the washing stations, but “usually” is doing real work there — Tanabe City’s guidance notes that some public baths do not supply them.
The four questions to send before you book
Send these to the facility, not to a booking site, and name the exact bath you intend to use in the message. Anything vaguer gets you a vague answer.
- Do you admit guests with tattoos, and does that answer apply to the specific bath I have named? A facility with a public bath, a private bath and a swimsuit zone can answer differently for each.
- If covering is required, what exactly counts — stickers, a rash guard, tape — and is any of it sold or rented on site? This is the question that stops a covered tattoo turning into a refusal at the counter.
- Is a private bath available on my dates, how far ahead must I reserve it, and can I book online? Hakone Yuryo, for one, publishes a one-month booking window that closes at 15:00 the day before, so “we’ll sort it out when we arrive” is not always an option.
- What is included with my ticket, and what must I bring or buy — towels, indoor wear, soap, a swimsuit? Ask it as a list, because facilities answer this one item by item.
If you use a bathing garment made for covering surgical scars, add it as a fifth line to the same message rather than assuming: Yunessun states that you may bathe wearing one but that it does not supply them, so you bring your own. That message is the whole of your preparation. Everything after it happens at the building itself, starting at a doorway you have to read correctly.
Arriving at the Onsen: Shoes, Changing Rooms and Getting Undressed
The doorway is the one part of the visit where being confident is worse than being slow. Many ryokan swap which bath is the men’s and which is the women’s between the evening and the next morning, so the curtain you walked through last night can be the other one by breakfast. Tanabe City’s tourism bureau puts it plainly in its bathing guidance: confirm the correct one before entering, every time.
Colour will not save you. Blue for men and red for women is the common pattern, and japan-guide’s bathing procedure warns in the same breath that it is not always the case. What does not vary is the writing. Japan’s national tourism organisation tells visitors it is safer to go by the kanji than the colour: 女 for women, 男 for men. Those two characters are worth thirty seconds of memorising before you travel, and there is a second one worth knowing because it does not help — 湯, meaning hot water, appears on both sides, so a curtain reading only 湯 has told you nothing.
What this actually costs is visible in an r/JapanTravelTips post from April 2025. A guest at an onsen ryokan described standing in the men’s changing area after his morning bath when a woman walked in; he stopped her, and noted that had he not been there, she would have had no reason to notice anything, because that room had been the women’s side the day before. In the same thread another long-term resident wrote that it had happened to him too, and that it happens to Japanese guests and foreign guests alike — usually on autopilot in the morning, not reading the sign. A third described his wife being caught out at a Kinosaki ryokan years earlier, where the noren were not red and blue at all but light brown and dark brown.
So the habit, not the fact, is what you take away: read the characters on every single entry, including the second visit to a building you think you know. If the bath rotates, the schedule is normally posted at the changing-room entrance or at the front desk, and it is a fair thing to ask about at check-in rather than at 06:00 in a towel.
Inside, the sequence is quick. Shoes come off at the entrance, usually into a shoe locker before you reach the changing room at all. Clothes and valuables go into a basket or locker, and so does your phone — Hakone Yuryo’s house rules prohibit using cameras and phones in the changing room and bath area of its public baths, and Yunessun states that photography is prohibited in its Mori no Yu bathing area and its changing rooms. That is not a quirk of two facilities; assume it everywhere and you will never be the person being asked to put something away. Rings, watches and necklaces are worth leaving in the locker too, because Tanabe City’s guidance notes that the minerals in the water can discolour them.
Then you undress completely, and you take exactly one thing through the door with you. The small towel does three jobs across the visit — washing, modesty, and a first dry-off at the end — while the large one stays in the changing room, which is the distinction japan-guide draws between the two. Long hair gets tied up now rather than at the bath’s edge.
The modesty question is the one people actually lose sleep over, and it has a concrete answer. On the japan-guide forum, a visitor planning a first trip to a Hakone onsen wrote in June 2015, “I have issue with totally naked in front of strangers,” and asked what to do with the small towel while walking to the bath. The most useful reply in the thread separated two things that beginners collapse into one: holding the small towel in front of you while you move around the bathing room is normal and unremarkable, and it is only when you get into the water that the towel has to leave your body. Tanabe City’s guidance describes the same practice from the other direction, noting that you can cover yourself with the small towel while walking between the changing room and the bath. Nobody is asking you to walk in unshielded; they are asking you to keep the towel out of the water.
Which is the point at which the towel stops being about privacy and starts being about hygiene — and that switch happens at the washing station, a few steps away.
Washing Before You Soak: What to Do at the Shower or Wash Basin
You will have read two different instructions for this step, and both of them are real. Hakone’s tourist association tells visitors to wash your body completely before entering the shared bath and to rinse off any soap first. japan-guide’s procedure page opens the same step with rinsing your body well, using a trough, a tap, a bowl or a shower. Tanabe City’s guidance splits the difference in three words: rinse or wash.
They are not contradicting each other. They are describing the same threshold from two distances, and the threshold is this: you get into shared water clean, with no soap left on you. Hakone’s guidance gives the reason in one line — you clean yourself out of respect for the cleanliness of the water and the bathers who follow you — and Tanabe’s guidance states the operating principle as keeping the bathwater separate from the washing water. That is the whole mechanism. The bath is not a cleaning device; it is the thing being kept clean, and everything that happens at the washing station exists to stop your dirt and your soap arriving in it.
Once you see it that way, the wash-or-rinse question answers itself by situation. On a first visit, arriving from a day of travel, wash properly — soap, shampoo if you want it, and a complete rinse. On a second or third soak later the same day, when you are already clean, a rinse is what the sources are describing. Tanabe’s guidance sets out that pattern exactly: some people do a quick rinse, soak for a little while, then do a thorough washing and return to the bath once they are clean.
The part nobody prepares you for is that the washing area itself is not standardised. Most have seated shower stations with a detachable head, a bowl and a stool. Some have taps and buckets and no shower at all. In a November 2025 thread on r/JapanTravelTips, one commenter described her first onsen as an old-school public bath with no showers, where you crouched on the floor beside the bath and washed by scooping water out of it with a bowl — which she found, in her words, awkward for a newbie. Tanabe City’s guidance describes exactly that method as the correct one where there is no shower: fill the washbowl from a tap or scoop from the bath, crouch beside it rather than in it, start at your feet and shins and work upwards, and let the water you have used run away to the drain instead of back into the bath.
Two practical things, because they are the questions people are too embarrassed to ask, and on the first one the official guidance and the lived practice do not quite line up. Tanabe City’s instruction is to sit on the stool while you wash, for the plain reason that standing sends water onto the people beside you and into the bath. The bathers in that thread — including one who introduced herself as a Japanese woman — said that lifting off the stool or briefly standing to wash properly is unremarkable and that nobody is paying attention. Both are right, and the thing that reconciles them is the splash, not the posture: get clean however you need to, keep the spray low and aimed down, and sit back down. The second question is hair, and washing it is optional in a way that keeping it out of the water is not. Tie it up either way.
Two habits finish the step. Rinse every trace of soap off your body before you stand up, because soap on skin is the one thing that definitely reaches the bath. And rinse the stool and the bowl and leave the space as you found it, which is the small courtesy that marks the difference between a visitor who has read a list and one who has understood why the list exists.
Clean, soap-free and dry-haired, you are ready for the water itself — where the rules stop being about hygiene and start being about the fact that other people are in there with you.
In the Bath: Towels, Hair and Onsen Etiquette
Your towel does not come into the water with you. That is the one instruction every source agrees on without qualification, and Tanabe City’s guidance says plainly where it goes instead — set your towel on your head or on the side of the bath. Japan’s Ministry of the Environment states it as a flat line in its bathing cautions — do not put towels in the bathtub — and the Japan Onsen Association gives the reason in the same breath, to keep the water hygienic.
What makes the rest of Japanese bathing etiquette easier to hold in your head is noticing that these are not all the same kind of rule. Some protect the water, some protect the people around you, and some protect you. They get printed as one undifferentiated list, which is why they feel arbitrary and impossible to memorise. Split them three ways and you can work out the answer to something nobody wrote down.
The water rules are the absolute ones, and Beppu City publishes an unusually complete set of them in the English living guide it gives residents, on printed page 43. No towels in the bathtub. Tie long hair so it cannot get into the water. No swimming and no diving. No food or drink in the bathroom, and no washing clothes there either. Nothing that was on your body or in your bag goes into water that other people are sitting in — that is the entire logic, and once you have it you will not need the list.
Which brings up the thing that actually happens and that almost no guide covers: your towel falls in. It is a small, common, mortifying accident, and there is a correct move. Tanabe City’s tourism bureau states it directly — if your towel accidentally falls into the bath, wring it out outside the bath. Not over the water, not back into it. Lift it out, step or lean clear, wring it onto the floor where the drains are, carry on. The mistake is not the towel going in; the mistake is wringing it out where it went in.
The second group — the rules that protect other people — are softer, and Beppu City frames them in a sentence I have not seen in any commercial guide: some people like hot water, others like warm water in the bathtub, so please enjoy bathing while getting along with each other. That is the standard being applied to you. Not silence, not stillness, just the ordinary awareness that the bath belongs to everyone in it. Concretely, from the same page: do not leave your belongings in the washing area to save a place, and do not disturb other customers. Keep your voice down, keep your movements unhurried, and give people room. If a bath is crowded, do not spread out in it.
The third group is about your own body, and this is where the tone should change, because it is the only part of an onsen visit that can genuinely go wrong. The Ministry of the Environment’s March 2019 booklet, compiled under the supervision of the Japanese Society of Balneology, Climatology and Physical Medicine, sets out its bathing cautions plainly: avoid bathing immediately before or after a meal or after drinking alcohol; hydrate before and afterwards; avoid bathing when you are over-tired or within thirty minutes of exercise. It also lists conditions under which a person should not bathe at all, and states that the elderly, children and people with disabilities should not bathe alone. Beppu City’s guidance adds the warning a first-timer is most likely to need: get in gently after rinsing, because entering a hot spring suddenly can make you feel dizzy.
Two things follow from that, and both are practical rather than medical. First, if you start to feel unwell, get out — Tanabe City’s guidance says exactly that, and the Japan Onsen Association adds the safe way to do it: leave the bath slowly, keep your head low, and ask the people around you for help. Stand up slowly in any case, because standing too quickly is how people faint. Second, do not treat soak time as a target. Both the Ministry and Beppu City frame the figure they publish the same way — around three to ten minutes to begin with, depending on the temperature of the water, extending as you become accustomed to it — which is guidance for acclimatising, not a duration you are supposed to achieve. Nobody is timing you. Get out when you are warm, sit on the side, go back in if you want to.
If you have a heart or lung condition, high blood pressure, are pregnant, or are taking medication, the booklet’s cautions and contraindications are worth reading in full before you travel, and the question of whether hot-spring bathing suits you is one for your own doctor rather than for a travel guide. What the etiquette can tell you is everything up to that line, and the last of it happens on the way out.
After Soaking: Rinsing, Drying Off and Cooling Down
The cue for getting out is not a clock. The Unzen Tourist Association, in the bathing principles it publishes for its own sulphur springs, gives a physical one instead: bathe until your forehead is slightly perspiring, and when you feel that, take a break by getting out of the bath. It is a better instruction than any number, because it adjusts itself to the water temperature, the day and you.
Then comes the one post-bath question with a genuinely split answer. Almost every English guide says the same thing — do not rinse, leave the minerals on your skin — and states it as a rule. The official position is narrower than that. The Ministry of the Environment’s booklet says it is preferable not to rinse the onsen constituents off the body, and to wipe moisture off with a towel instead, in order to keep those constituents on you. It then attaches an exception in the same breath: it is better to rinse off if you have sensitive skin, or if the onsen contains stimulant constituents, naming acidic springs and sulphur springs specifically.
Unzen is the useful illustration, because it applies that exception to itself. Its springs are sulphuric and strongly acidic, so the association tells visitors that people with sensitive skin should rinse off with fresh water — on the same page where it explains why, ordinarily, you would not. Two rules, one source, no contradiction. The practical version: default to not rinsing, and rinse if your skin is reactive, if the water is acidic or sulphurous, or — the reason nobody official mentions but the forums do — if you would rather not carry the sulphur smell to dinner. One poster in the japan-guide thread listed exactly that as his final step, and it is a perfectly good reason.
The genuinely under-explained part is the drying, and it is under-explained because it is two separate actions that guides compress into one. In that 2015 forum thread, the original poster asked it directly — if I want to get out, do I wash at the wash area and then wipe myself dry, is that the correct sequence? The answers were consistent. You wipe down with your small towel while you are still in the bathing room, and then you dry properly with the large towel once you are at your locker. As one respondent put it, wipe your body and hair before you leave, because dripping around the changing room is bad manners; then dry off thoroughly with the bath towel when you get to the changing room. Another added the detail that makes it work: wring the small towel out first so it is dry enough to take the excess water off you.
That is not just courtesy. Beppu City puts it among its printed rules for residents — do not go into the changing area from the bathroom with a wet body — and the reason is the obvious one. The changing room has your clothes in it, and everyone else’s, on a floor that is meant to stay dry.
What is left is the part travellers skip because they have somewhere to be. Both Beppu City and the Unzen association say some version of it: do not let yourself get cold, and rest. Unzen suggests around half an hour of sitting quietly, on the grounds that blood pressure takes a couple of hours to settle, and adds that you should rehydrate after sweating and that bathing repeatedly through the day is more tiring than people expect. The Ministry’s booklet also lists hydrating before and after bathing among its cautions. If the building has a tatami lounge or a bank of chairs and a drinks machine, that is what they are for.
Your first visit, in order
- Read the characters on the curtain — 女 women, 男 men — and check again on every later visit, because many places rotate the baths.
- Shoes off at the entrance. Clothes, valuables, phone and jewellery in the locker.
- Undress completely. Take only the small towel. Tie up long hair.
- Sit at a washing station and wash, working upwards from your feet. Rinse off every trace of soap.
- Get in gently. Towel on your head or on the side, never in the water.
- Get out when your forehead starts to perspire. Sit out, cool down, go back in if you want to.
- Wipe down with the small towel before you leave the bathing room; dry properly with the large towel at your locker.
- Rehydrate and sit for a while before you go anywhere.
Where First-Timers Actually Slip Up
The sequence itself is not where people come unstuck — it is eight steps long, it is the same almost everywhere, and you now have it. What catches visitors out is arriving with a general answer to a question that only the individual bath can answer, and then discovering the difference at the counter with their luggage in their hand. So do the one thing this whole guide is built around: before you book, send that facility the four questions, naming the exact bath you intend to use. Everything else you can work out on the day, including the parts you get slightly wrong.
Frequently asked questions
Can I use an onsen during my period? The published guidance says no, and it is worth knowing that this is a house rule rather than a law. Beppu City lists it among the bathing manners in its own residents’ guide — refrain from bathing when you have your period — and Tanabe City’s tourism bureau says menstruating women should refrain from using communal baths. Facilities rarely check and rarely post it in English, which is why travellers find contradictory advice in forums, but the official position from both a city government and a regional tourism authority is consistent. If your dates are fixed, this is the clearest case for booking a private bath, where the water is not shared.
Is a sento the same thing as an onsen? No, and the difference is legal rather than atmospheric. Japan’s national tourism organisation explains that a sento generally uses ordinary heated water, while a facility has to meet strict criteria before it can call itself an onsen — chiefly that a good part of its water comes from a natural, geothermal, mineral-rich source. The etiquette in this guide applies to both. The practical difference is that the post-soak rinsing question only really arises at an onsen, because at a sento there are no spring constituents on your skin to leave there.
Can I drink the hot spring water? Only where drinking is explicitly permitted, and then in small amounts. The Ministry of the Environment’s booklet sets out drinking as a separate practice with its own rules: drink only from an onsen where it is allowed, take roughly 100–150 ml at a time and no more than about 200–500 ml a day, and do not carry it away from the place. Beppu City makes the same point more briefly, noting that you can only drink from hot springs approved for drinking. The booklet also sets lower limits for people with specific conditions and says drinking onsen water as a treatment is something to discuss with a doctor first.
Can I bathe in an onsen while pregnant? The Ministry’s booklet answers this one directly: yes, pregnant women can bathe in onsen, with the caveats that they should not bathe for too long or in high-temperature water and should be careful of slippery floors. That is the official position as published, not a clearance for your particular situation — if you are pregnant or managing any health condition, the booklet’s full list of cautions and contraindications is the right thing to read, and your own doctor is the right person to ask.
