Onsen etiquette for couples: tattoos, rules and private baths

Onsen, Japan's hot springs, are one of the most typical Japanese experiences, but they can be confusing the first time: you bathe without clothes, you wash before getting in, and tattoo policy differs from one venue to the next. This guide summarises what the Japan National Tourism Organization (JNTO) says in its official guidance so a couple can enjoy onsen with confidence, including the option of private baths. It is informational content.

Quick summary

• At public onsen you bathe without clothing or swimwear; clothes stay in the changing room.
• Before entering the bath you wash your whole body at the shower stations.
• Tattoo policy depends on each facility, so asking in advance is the safest course.
• Most public baths are gender-separated. To go together, the usual choices are a private bath (kashikiri) or a bath in your room.

Basic bathing rules

According to JNTO, bathing is usually done without clothes, with a small towel used for covering up and washing. The main rules are:

• Keep your towel out of the water: place it on your head or on the edge.
• Wash thoroughly, seated at the shower stations, with soap, before getting in.
• Keep your hair out of the water; tie up long hair, and even with short hair do not fully submerge.
• Do not eat or drink in the bath. As a rough guide, soaking should not exceed about 30 minutes.
• Clothes and valuables go in lockers or baskets; jewellery can discolour in the mineral water.
• At ryokan and hotels, guests often walk to the bath in a yukata and slippers.

Separate baths and private baths

Most public baths are gender-separated, with blue curtains for men and red for women. Mixed-gender onsen exist, but they are rarer and harder to find. If you are uncomfortable undressing in front of others, or you want to bathe together, there are alternatives:

Private bath (kashikiri). A room reserved for one group at a time, usually for an extra fee. Sometimes you must book ahead or collect a key at the front desk. A small group can rent one together.

In-room bath. Some accommodation includes it in the room price, and it lets you bathe without schedules.

Foot bath (ashi-yu). Only your feet go in, fully clothed, which is an easy way to sample the experience.

Tattoos

In Japan tattoos have historically been associated with crime, which is why some facilities refuse entry. There is no national rule: each place decides. JNTO explains that small or hard-to-see tattoos are often overlooked, that many venues are more flexible with international visitors, that skin-coloured stickers can cover small to medium tattoos, and that tattoo-friendly onsen can be chosen in advance. The safest approach is to email the facility or ask through the booking platform. Policies change, so check again shortly before you travel.

Tips for couples

For a first time, choose accommodation with a private bath. When booking, ask about the bath's schedule and price and about the tattoo policy. Inside the bath, keep the atmosphere calm and do not point a camera or phone toward other bathers; many venues forbid photography in changing rooms and baths. Afterwards, drink water and avoid bathing after drinking alcohol. If you have a health condition or are pregnant, check with a doctor first.

Checklist before you book

• Confirm whether a private bath exists, its schedule, its price and how to reserve it.
• Ask about the tattoo policy in writing, by email or through the booking platform.
• Check the opening hours of the general baths and the cleaning times when you cannot enter.
• Bring a small towel or check whether the accommodation lends one.
• Skip the bath if you feel unwell or have been drinking alcohol.

Frequently asked questions

Can I wear swimwear? At ordinary public onsen it is not expected. If a facility allows it, it says so.

Can we bathe together? General baths are usually gender-separated; options are a private bath, an in-room bath or a mixed onsen.

Can I enter with tattoos? It depends on the facility: ask beforehand or choose one that accepts them.

What if I do not understand the language? Many facilities have pictograms or English instructions for the washing routine; if in doubt, ask staff.
