Book somewhere with a big bath

The private bath is the easy booking

And that is exactly why people default to it. It is certain. Nobody is going to look at you, nobody is going to ask you anything, and there is no policy to read twice before you pay. When you have spent an evening working out which baths in Japan will let you in, the private one is a relief.

It is also, almost always, small. A wooden tub for two on a balcony, or a stone basin off a corridor, with a forty-five-minute slot and a little clock on the wall. That is a nice thing to have done. It is not really the thing.

What the big bath actually is

A daiyokujo is a room, not a tub. The water runs the length of it and is deep enough to sit in up to your shoulders. There are usually two or three of them at different temperatures, a row of taps along one wall, and often a door to an outdoor bath — where the ceiling is simply the sky, and the steam goes straight up into cold air while you sit in water hot enough to make your ears ring.

You cannot book that for yourself. It is that size precisely because it was built for everyone in the building, and being in it with other people is not a cost you pay for the scale — it is the thing itself. Fifteen strangers sitting quietly in hot water at the end of a day is a specific and rather good feeling, and there is no private version of it.

It asks nothing of your Japanese

This is what makes it such an easy piece of Japanese life to join. A restaurant needs vocabulary. A shrine needs somebody to explain it. A bath needs you to do the same four things everybody else in the room is doing, in the same order:

• Undress completely in the changing room. All of it — there is no swimwear in this.
• The small towel does not go in the water. Most people park it on their head, which looks ridiculous and is entirely normal.
• Sit at one of the taps and wash first, properly, with soap, then rinse it all off. The bath is for soaking, not for cleaning.
• Get in slowly, keep your hair out of the water, and sit.

Nobody expects a visitor to know this in advance, and nobody minds a step done slightly wrong. Watch the person next to you and copy them. Ten minutes in, it stops feeling like a test.

Nobody is looking at you

The worry that sends people to the private booking is being stared at. In practice it is the least self-conscious room you will stand in all trip, for a very practical reason: when everybody is undressed, being undressed stops carrying any information. Eyes stay at eye level. People are looking at the water.

There is a Japanese phrase for what that does — 裸の付き合い, hadaka no tsukiai, roughly “naked company”. The idea is that people relate differently with nothing on, because everything that normally ranks a room is in a locker. Nobody in there knows what anybody does for a living, and for half an hour it does not come up.

You may end up talking to someone; you should not go in expecting to. Japanese baths are quiet and the default is a friendly nod. What happens more often is small and easy — somebody points you at the hotter bath, or asks where you are from and how long you are staying. A few sentences, and back to soaking. It is a very low-stakes way to have your first unplanned conversation in Japan.

And if you have tattoos

This is the part specific to why you are on this site, because the three routes feel quite different from the inside.

Under a cover seal it works, and a small part of your attention stays on whether the corner is lifting. In a private bath you have solved the problem by having the room to yourself. Both are real answers and both are listed here — 30 of the daiyokujo listings are the cover-seal kind.

Then there are the 33 places where tattoos are simply fine. No seal, no size limit, nothing to mention at the desk. You walk in, you wash, you get in the water, and nothing happens at all. Not hidden, not specially accommodated — just another person having a bath. If you have spent any time planning a trip around your skin, that ordinariness turns out to be the whole prize, and a private tub does not hand it to you.

No wrong answer

If your tattoo is large or full-body, most shared baths in Japan are still closed to you, and nothing we write changes that. If you are travelling with someone who would rather not, or you would simply like an hour by yourself, those are complete reasons. The 15 private baths here exist for them and are worth booking.

This is for the reader who could do either and picks the private one because it is the safer reservation. If that is you — take the big bath once. You can always have the quiet one tomorrow.
