Check the exact onsen's tattoo, private-bath, access, and bathing-hour rules before paying; the etiquette is easy once you know you can actually use the facility.
Quick answer: wash first, keep towels and hair out, and check facility rules before arrival
At a standard public onsen, remove all clothing in the changing room, take only the small washing towel into the bathing area, wash and rinse thoroughly at the shower station, and enter the bath without soap on your body. Keep the towel, hair, and head out of the water. Speak quietly, do not swim or splash, and leave phones and cameras outside the bathing area.
Tattoo, age, gender-area, day-use, accessibility, reservation, and bathing-attire policies belong to the individual facility. Some accept tattoos, some permit a small approved cover, some require a private bath, and others refuse entry. JNTO recommends checking in advance. A private kashikiri bath or a room with its own bath can also help travelers who want privacy, are uncomfortable with public nudity, or need to bathe with a partner or family group.
Onsen water can be hot, and mineral composition and facility warnings vary. Follow posted health guidance, avoid bathing while intoxicated, enter gradually, and leave if you feel dizzy or unwell. Travelers with pregnancy, cardiovascular concerns, skin conditions, recent surgery, mobility limitations, or other medical questions should seek individualized medical advice and confirm the facility setup before bathing.
Who this onsen guide is for
This guide is for first-time bathers, tattooed travelers, couples, families, solo visitors, shy bathers, gender-diverse travelers, and anyone choosing between a public bath, a private reserved bath, a day-use onsen, or an in-room bath. It explains the decision and sequence, but the exact facility's written rules always take priority.
| Traveler need | Best bath type to check | Question to ask |
|---|---|---|
| Standard first experience | Gender-separated public onsen | Are towels and toiletries provided, and what are the bathing hours? |
| Tattooed traveler | Tattoo-friendly public bath or private kashikiri bath | Are tattoos accepted, must they be covered, and what cover size is allowed? |
| Couple or mixed-gender family | Private reserved bath or in-room bath | Who may use it together, for how long, and is advance booking required? |
| Shy or privacy-focused traveler | Private bath or room with attached bath | Is the water onsen water and is the bathing area fully private? |
| Mobility concern | Accessible private bath or facility with assistance | Are there steps, handrails, bathing chairs, and accessible changing rooms? |
| Day visitor | Day-use onsen or ryokan bathing plan | What are last entry, closed days, payment, and luggage rules? |
Choose the right bath before you book
An onsen uses naturally sourced hot-spring water under Japanese rules, while a sento is generally a public bath using heated water. Both can provide a valuable bathing experience, and the etiquette is similar, but travelers should not assume every hotel bath is an onsen. Check the facility description if the water source matters to you.
A public onsen is the most traditional shared experience and usually the least expensive option. A kashikiri bath is reserved for private use for a defined time and may need advance booking or an extra fee. An in-room open-air or indoor bath offers the most privacy, but confirm whether it uses hot-spring water and whether the room layout meets your needs. A footbath is a low-pressure option when nudity, tattoo rules, time, or health considerations make a full bath impractical.
| Bath format | Best for | Check before choosing |
|---|---|---|
| Public onsen | Traditional shared bathing and broad facility choice | Tattoo, gender-area, age, towel, and health rules. |
| Day-use onsen | Adding a bath without an overnight stay | Operating hours, last entry, closed days, and luggage. |
| Private kashikiri bath | Privacy, couples, some tattoo situations, families | Reservation, fee, time limit, group rules, and accessibility. |
| In-room bath | Maximum privacy and flexible timing | Whether it is true onsen water and the room's bathing setup. |
| Sento | Local public-bath culture in cities | It may use heated tap water rather than hot-spring water. |
| Footbath | Short, clothed, low-commitment experience | Towel, footwear storage, opening hours, and skin/health guidance. |
Tattoo policy: never assume, and never hide a rule violation
Tattoo acceptance is changing, but there is no universal Japan-wide rule for private facilities. Check the official website and contact the property directly when the wording is unclear. Ask whether all tattoos are accepted, only small tattoos, an approved cover sheet, or private-bath use. Save the written answer if it affects a prepaid booking.
Do not cover a large tattoo secretly when the facility prohibits tattoos. Staff may ask you to leave, and the problem becomes an avoidable conflict. JNTO notes that some facilities sell or allow small cover sheets and that private baths are a useful alternative, but each onsen decides what is acceptable. A booking platform's generic tattoo-friendly filter is not a substitute for the property's current rule.
| Policy shown | Best action | Do not assume |
|---|---|---|
| Tattoos accepted | Confirm whether all bathing areas are included | A pool, sauna, or second bath has the same rule. |
| Small tattoos may be covered | Ask approved size, cover type, and purchase location | Any bandage or makeup is accepted. |
| Private bath only | Reserve the private bath before arrival | A room booking automatically includes a slot. |
| No tattoos | Choose another facility or an accepted private option | Staff will overlook it because you are foreign. |
| Policy not published | Email or call before paying | Silence means acceptance. |
Step-by-step: from changing room to final rinse
Step 1: identify the correct bathing area. Curtains and signs can change by time or day at some properties, so use the current sign rather than memorizing a color. Remove shoes where directed. Step 2: place clothing and large towel in the locker or basket, secure valuables as the facility instructs, and enter the bathing area without swimwear unless that specific facility explicitly requires bathing attire.
Step 3: sit at a washing station, keep the shower low, wash your body and hair thoroughly, and rinse away all soap. Rinse the stool and area when finished. Step 4: use kakeyu or enter gradually to adjust to the water, following posted instructions. Tie up long hair. Leave the small towel on your head, the pool edge, or another permitted dry place, never in the bathwater.
Step 5: soak quietly without swimming, splashing, exercising, or blocking the entry steps. Do not submerge your head. Give other bathers personal space. Step 6: leave the bath when you have had enough, especially if you feel light-headed, overheated, or unwell. Follow the facility's instruction on whether to rinse after soaking because mineral water and local practice vary.
Step 7: wipe excess water from your body with the small towel before returning to the changing room so the floor stays dry. Dry fully with the large towel, dress, hydrate as appropriate, and return locker keys or rented items. If you borrowed a yukata, follow the ryokan's directions for wearing and returning it.
Health, heat, alcohol, and access cautions
Do not use an onsen while intoxicated. Eat and drink sensibly around bathing, follow facility warnings, and do not compete to stay in very hot water. Move slowly when standing because heat can make some people feel dizzy. If you feel unwell, leave the bath, sit safely, and alert staff or a companion.
Mineral composition, water temperature, steps, floors, and handrails vary. People with medical, pregnancy, skin, wound, infection, or mobility concerns need advice specific to their condition and the facility. A private bath offers privacy but does not automatically make hot water medically suitable or physically accessible. Ask about bathing chairs, rails, transfer steps, and companion assistance before booking.
Phones, towels, hair, and personal belongings
Leave phones, cameras, and smart devices outside the bathing area. Privacy is strict even if the bath appears empty. Do not take photographs through a doorway or from the changing room. Use only the small towel where permitted and keep the large towel dry in the changing area.
Tie long hair before entering. Remove jewelry if the facility advises it, because minerals can affect some metals and lost items are difficult to recover. Use a locker for valuables when available; an open basket is not secure storage. Bring a hair tie, a small waterproof pouch for locker keys if allowed, and any approved tattoo cover already confirmed with the facility.
Common etiquette mistakes and fixes
Most first-time mistakes come from treating an onsen like a swimming pool or hotel spa. Slow down and copy the functional sequence: change, wash, rinse, soak quietly, dry before returning. You do not need to imitate every gesture of another guest, and you should not follow a guest who ignores posted rules.
| Mistake | Why it matters | Correct action |
|---|---|---|
| Entering before washing | Shared water is for soaking, not cleaning | Wash and rinse thoroughly first. |
| Putting a towel in the bath | It contaminates shared water | Keep it on your head or in a permitted dry place. |
| Letting hair touch the water | Hair should stay out of the bath | Tie or wrap long hair securely. |
| Wearing swimwear | Standard onsen are usually nude bathing | Follow the facility's explicit bathing-attire rule. |
| Taking a phone inside | It violates other guests' privacy | Leave all camera-capable devices outside. |
| Assuming tattoo acceptance | Policies differ by facility and bathing area | Confirm before paying or reserve a private option. |
| Staying despite dizziness | Heat can make symptoms worse | Leave promptly and tell staff if needed. |
What to verify with the facility
Check the official property page for tattoo policy, bathing hours, closed days, private-bath reservations, day-use last entry, age rules, gender-area arrangement, towel rental, payment, luggage, accessibility, and maintenance notices. If any answer affects whether you can bathe, contact the property before the cancellation deadline.
- Confirm tattoo rules in writing when they affect the booking.
- Confirm whether a private bath needs a separate time reservation.
- Confirm accessibility details rather than relying on a general accessible-room label.
- Confirm bathing hours and cleaning closures after check-in.
- Follow posted health, hygiene, and photography rules at the facility.
If you only do one thing
Check the exact onsen's tattoo, private-bath, access, and bathing-hour rules before paying; the etiquette is easy once you know you can actually use the facility.

FAQ
Do I have to be naked in a Japanese onsen?
In a standard public onsen, yes: clothing and swimwear are usually left in the changing room. Some special facilities use bathing attire, so follow the exact facility's posted rule.
Can I enter an onsen in Japan with tattoos?
It depends on the facility. Some accept tattoos, some allow an approved small cover, some require a private bath, and some refuse entry. Confirm before paying.
Do I wash before or after entering the onsen?
Wash and rinse thoroughly at the shower station before entering the shared bath. Follow the facility's local instruction on whether to rinse after the final soak.
Can my towel go into the onsen water?
No. Keep the small towel on your head, on the bath edge, or in another permitted dry place, and keep the large towel in the changing room.
Can couples use an onsen together?
Most public baths are gender-separated. Couples or mixed-gender families should look for a private kashikiri bath or an in-room bath and confirm the group rule in advance.
Can I take photos in an onsen?
Do not bring a phone or camera into the bathing or changing area. Other guests' privacy applies even when the room seems empty.
What should I bring to an onsen?
Bring a hair tie, payment, and any facility-approved tattoo cover. Confirm whether small and large towels, toiletries, lockers, and a yukata are included or rented.
How long should I stay in an onsen bath?
There is no single safe time for every person or bath. Follow facility guidance, enter gradually, avoid intoxication, and leave immediately if you feel dizzy, overheated, or unwell.
