Onsen etiquette and the tattoo rule: what signs say in 2026

The sign on the door of a neighborhood bath in Beppu had three lines. The top two, one in Japanese and one in English, said no tattoos. The third was handwritten on masking tape and stuck underneath: small ones are fine with a sticker, ask at the counter. The friend traveling with me has a tattoo on the upper arm about the size of a playing card, and that strip of tape was the most useful thing I read all September.

My friend bought a skin-colored patch at the counter and we both went in. Two doors down, the day-use bath at a larger inn had a sign with one line on it, and the line was no. Both were within sight of the same bus stop.

That is the pattern behind most of what gets written about onsen and tattoos. The rule is real, each door sets its own version, and the door usually tells you which one you are dealing with. What follows comes from six days in Beppu and Yufuin in early September 2026 and nine years of getting the basics wrong around Fukuoka.

Shoes come off at the entrance and go into a locker or onto the shelf. Pay at the counter or the ticket machine. The neighborhood baths I used cost a few hundred yen, and the inns that take day visitors charge more. You get a small towel there, or you buy one, or you bring your own. A big bath towel stays in the changing room.

In the changing room you undress completely and put everything in a basket or a locker. Many old lockers want a ¥100 coin that comes back when you open the door, so carry one. Swimsuits are not allowed, and that surprises more first-timers than the tattoo question does. You take only the small towel, about the size of a hand towel, and hold it in front of you for the walk through.

The washing area is a row of low plastic stools with taps and hand showers along the wall. Sit, wash everything with soap, and rinse the stool when you are done. You will hear it before you see it: a dozen small buckets knocking on wet tile, and the hiss of showers. Hair below the collar goes up. Then pour a few buckets of bath water over yourself, slowly, starting at the feet. This is called kakeyu, and it also tells you what the tub is going to feel like. If the water in the bucket seems too hot, the tub will seem hotter.

Get in without splashing. The small towel stays out of the water, folded on your head or left on the rim. In 2017, my first winter in Fukuoka, a man in his seventies lifted mine out of the bath with two fingers, held it away from himself like a wet fish and handed it back without a word. I have not made that mistake again.

Most baths run between 40 and 43°C. Stay about ten minutes, sit on the edge, get back in if you like. If your head goes light, get out. The Japanese word for the sick, slow feeling of too much hot water is yuatari, and it comes faster after a beer. Before you return to the changing room, wring out the towel and wipe yourself down so you do not leave a trail on a floor other people will walk on. No photos, no swimming, no phones past the changing room.

Not every public bath is generous. Some supply soap and shampoo, many do not, and I have stood in a spotless Beppu changing room holding a sample sachet of face wash for lack of anything else. A small bag with soap, a comb and a hair tie weighs almost nothing.

No national law bans tattoos in baths. Each facility sets its own rule, and the reason given most often is the old link between tattoos and organized crime, which makes some regular customers uncomfortable. The rule applies to tattoos as such, so a small design on an ankle counts, and so does a temporary one large enough to be mistaken for the real thing. Foreign visitors are held to the same standard as everyone else, which at least makes it predictable.

Over six days in Beppu and Yufuin I wrote down the tattoo line on every bath I walked into or past. There were fourteen. Nine said no without exceptions. Three allowed small tattoos under a sticker, and one of those sold the stickers at the counter. Two let anyone use a private bath by the hour, tattooed or not. That is one trip through one corner of Kyushu, and the same exercise in Hakone or Yamagata would give different numbers.

The no is easiest to find at public baths and at the big day-use spa complexes. Inns that live on overnight guests bend more often, and they are the ones with private baths. I skipped the large complexes, the ones with a dozen pools, a food court and a manga room. They are the likeliest to refuse, and I would skip them with or without a tattoo: the pools I have tried were lukewarm and filtered, the changing room had the hush of a gym, and the price was well above a neighborhood bath.

Lists of tattoo-friendly baths online need a date check before you trust them. I tried five places from one list. One now said no, and one told me, politely, that it had never said yes.

Most of the vocabulary fits on a card. These are the ones I met in September, with the romanization I use to say them out loud.

• 入れ墨お断り or タトゥーお断り (irezumi okotowari, tatū okotowari): no tattoos. Okotowari is a polite refusal, closer to "we must decline" than to "forbidden".

• シール (shīru) is a sticker, 可 (ka) means allowed and 不可 (fuka) means not allowed. シールで隠せば可 means allowed if covered with a sticker.

• 貸切風呂 (kashikiri-buro) and 家族風呂 (kazoku-buro): a private bath rented by the slot. A board at the desk often lets you turn a tag to 使用中 (shiyōchū), in use.

• 日帰り入浴 (higaeri nyūyoku): day use for people who are not staying. The hours and the price sit on the sign, and the hours can be short.

• 清掃中 (seisōchū): cleaning. The bath is closed even if the door is open.

• 男湯 (otoko-yu) and 女湯 (onna-yu): men's and women's. The curtain is usually dark blue for men and red for women, but some baths swap sides by the day or the hour, so read the characters.

• 混浴 (konyoku): mixed bathing. None of my fourteen were.

The word to read is the last one on the line. お断り is no. 可 is yes. Anything vaguer is an invitation to ask.

The worst place to learn the rule is the lobby, in slippers, with luggage. Ask when you book. Most inns that take reservations from abroad answer in English, and a short message does the job: I have a tattoo on my upper arm about the size of a playing card, can I use the large baths, or do you have a private bath? In September the replies I got were yes with a sticker, no to the large bath but a private bath available, and a plain yes. None of them minded the question.

On the phone, or at a counter where English runs out, these two sentences get you most of the way. タトゥーがあるのですが、入浴できますか (Tatū ga aru no desu ga, nyūyoku dekimasu ka): I have a tattoo, can I bathe? And if it is small: 小さいので、シールで隠せば大丈夫ですか (Chiisai node, shīru de kakuseba daijōbu desu ka): it is small, is it all right if I cover it with a sticker?

Stickers are sold at drugstores and online, in skin tones, waterproof. One fits a design up to about the size of a playing card. It will not hide a sleeve. In 41°C water the edge of my friend's started to lift after about eight minutes, and a wet sticker on dry skin is easy to spot if anyone is looking. It works because the staff agreed to it. Sneaking one past a door that says no is the one thing in this whole subject I would call rude.

The cleanest answer is a room with its own bath, heya-tsuki rotenburo on the booking page, or a kashikiri slot. It is also the most expensive. I priced the room-bath inns I saw in Beppu and Yufuin at $$$, against $$ for the same inns without the bath. Treat it as the splurge night. The ryokan in Ginzan Onsen on Haruki's Tohoku route lists private baths among its draws. Hakone has the same choice, covered in our where to stay in Hakone guide, and Beppu's public baths are in the Beppu guide.

The yukata, the cotton robe, has its own rule: the left side goes over the right. On my first night in Yufuin I wore it the other way, which is how it is worn for the dead. The person who brought the tea straightened the front with two quick tugs and said nothing, and I have checked it in the mirror every night since.

I also booked a private bath slot at a Yufuin inn and paid for it at the desk, when one slot was already included in the room rate. The line was in my confirmation email, which I had not read to the end. Read the confirmation before you open your wallet.

The last one is temperature. I gave up on a 44°C tub in Beppu after four minutes. The man beside me, who looked about eighty, had been in when I arrived and was still in when I left. Do not treat the number on the wall as a challenge.

If you have no tattoo, nothing in this guide changes your plans. Follow the routine, carry a coin and a small bag, and use any bath you like. Check the hours before you go, because many baths close for cleaning in the afternoon.

If your tattoo is smaller than a palm, book inns that say stickers are fine and ask first anyway. Pack two stickers in case one peels. Treat a no at a public bath as the end of that bath and move on.

If it is large or in a place no sticker covers, plan the trip around private baths. Book a room with its own bath for one night, add a kashikiri slot elsewhere, and leave the public baths and the big complexes off the list. You lose the neighborhood tubs and the sound of the washing area, and you keep the water.

On my last morning in Yufuin I booked the 8:00 slot at a private bath: 45 minutes, a cedar tub for two, a window onto the river and nobody to check my towel. I put it on my head anyway.
