Onsen Etiquette: A Step-by-Step First-Timer Guide
Quick answer
At a standard public onsen, undress, wash and rinse at the shower station, then soak quietly. Keep your towel and hair out of the water and your phone outside. Tattoo, swimwear and private-bath rules vary, so read the facility's signs first.
Am I ready to enter? The quick check
An onsen is a Japanese hot-spring bath shared by many people in the same water. The rules exist to keep that water clean and the space calm. Run through this check before you step in.
| Question | Answer (as of August 2026) |
|---|---|
| Which bath do I enter? | Read the words, symbols and facility signs; bath assignments can change by time. Ask staff if unsure. |
| Do I wear anything in the water? | No. Standard onsen are fully nude. Swimsuits only where clearly allowed. |
| Did I wash first? | You must wash and rinse fully at the shower stations before soaking. |
| Where does my towel go? | Use it to wash, then keep it out of the water. |
| Do I have tattoos? | Check the facility’s policy; some restrict shared baths. |
If you are clear on all five, you are ready. The full step-by-step below walks you through a typical visit.
How do I use the onsen, step by step?
The flow below covers a standard public bath as of August 2026; posted local instructions always take priority:
- Pay or check in, read the facility rules, and confirm the correct entrance. Do not rely on curtain color alone.
- Enter the changing room. Undress completely and put everything in a locker or basket. Take only your small towel.
- Go to the washing area. Sit on a stool at a shower station. Wash your whole body with soap and shampoo, then rinse off every trace of suds.
- Enter the bath slowly. Use kakeyu if provided and lower yourself in gently; temperatures differ by bath.
- Soak quietly. Keep your towel out of the water, on your head or at the edge. Do not swim, splash, or make calls.
- Cool down between soaks if you feel hot. Drink water afterwards to rehydrate.
- Rinse or do not rinse according to preference and local instructions. JNTO notes there is no single correct final-rinse style. Dry your body before returning to the changing area.
That is the whole visit. Relax and take your time; there is no rush.
What should I never do in an onsen?
A few actions break the shared-water rule or the calm mood. Keep this list in mind.
| Do | Do not |
|---|---|
| Wash and rinse fully before entering | Get in dirty or with soap on you |
| Tie long hair up | Let hair or towel touch the water |
| Talk softly | Swim, splash, or be loud |
| Leave your phone in the locker | Take photos in bath or changing areas |
| Hydrate outside the bathing area | Bring food, drink, or alcohol into the bath |
| Sit calmly to soak | Dunk your head underwater |
Most of these protect the water everyone shares. Following them marks you as a considerate guest.
What about tattoos, mixed baths, and private options?
Two situations need a little planning. Tattoos: as of August 2026, policies vary by facility. Some onsen welcome tattoos, some accept an approved cover sheet for a small tattoo, and some restrict shared-bath entry. Mixed or private baths: clothing and booking rules can differ, so do not assume a private bath automatically permits swimwear or overrides the facility’s policy.
| Option | What it means | Good for |
|---|---|---|
| Standard public bath | Nude, gender-separated | Most visitors |
| Tattoo-friendly onsen | Tattoos allowed openly | Guests with tattoos |
| Cover-sticker policy | Small tattoos covered | Guests with small tattoos |
| Private (kashikiri) bath | Reserve the whole bath; facility rules still apply | Families and guests wanting privacy |
Check each facility’s stance before you go, especially for tattoos. Our guide on tattoos and onsen covers the workarounds in detail.

Final tips for a smooth first visit
Onsen bathing is relaxing once the flow feels natural. Stay hydrated outside the bathing area, enter gradually, and read the local signs rather than copying a rule from another facility. If you feel dizzy or unwell, leave the water, cool down, and ask staff for help. Anyone with a condition affected by heat should follow medical advice before bathing.
Above all, the rules come down to one idea: keep the shared water clean and the space calm for everyone. Get that right and you will be a welcome guest at any onsen. For more on customs, see the official JNTO etiquette pages above.
FAQ
Do I wear a swimsuit in a Japanese onsen?
No. As of August 2026, a standard public onsen is usually used nude, without swimwear. Some mixed, themed or private facilities have different clothing rules. Read the entrance signs and ask staff before changing; permission at one bath does not establish the rule at another.
Do I have to wash before getting in the onsen?
Yes, always. Before entering the shared bath you must wash and rinse your whole body at the seated shower stations, removing all soap. The communal water is for soaking, not cleaning. This is the single most important rule, because everyone shares the same water without it being drained between guests.
What do I do with the small towel they give me?
Use the small towel to wash at the shower station, then keep it out of the bath water. Most bathers fold it and rest it on their head or set it at the edge of the bath while soaking. Wringing it into the bath or letting it float in the water is not done. Dry off roughly with it before returning to the changing room.
Can I use an onsen if I have tattoos?
It depends on the facility. As of August 2026, some shared baths restrict tattoos, some accept them, and some allow only small tattoos covered with an approved sheet. Check the bath's own policy before arrival. If the shared bath cannot admit you, ask whether a reservable private bath is available.
Is it rude to soak with long hair loose or to take photos?
Tie long hair up so it does not touch the water. Photos are not allowed in the bathing and changing areas to protect everyone's privacy, so leave your phone in the locker. Talk quietly, do not swim or splash, and do not bring food or drink into the bath. The atmosphere is calm and relaxing for all.
