Onsen Etiquette for First-Timers
Onsen etiquette for first-timers starts with one rule: wash your whole body before you touch the shared water.12 Everything else follows from that idea of keeping communal mineral water clean and calm.
Fees, rules, and requirements can change. Confirm current details at the Japan National Tourism Organization (JNTO) site.
Overview
An 温泉 (onsen, "hot spring bath") is fed substantially by natural geothermal mineral-rich water.34 Onsen are found across the country, and the water's composition varies from area to area.5
A 銭湯 (sento, "public bathhouse") uses ordinary heated tap water instead, but the manners inside are nearly identical.3 Sento historically served households that had no bath of their own.6
The bath is for soaking a body that is already clean, not for washing.12 You will bathe nude alongside strangers in most communal baths, so the routine protects both hygiene and comfort.
The Bathing Sequence, Step by Step
Take off your shoes at the facility entrance, before you reach the changing room.1 Put valuables in a coin locker or safe box where one is provided, or in your room safe if you are an overnight guest.21
Undress fully in the changing room and carry only your small towel into the bathing area.2 Lockers or baskets hold your clothes, and jewelry is best left behind because minerals can discolor metal.3
The full order looks like this:
Wash first at the washing station
Sit at an 洗い場 (araiba, "washing area") beside the main bath.12 Each station typically offers a low stool, a basin or bucket, a handheld shower, plus free shampoo, conditioner, and body soap.123
Wash your whole body and rinse until no soap remains.12 Sitting keeps spray off neighbors, and tidying the stool and basin after use is part of the manners.2 Remove makeup before you start.1
Before entering the tub, pour hot water over your body as 掛け湯 (kakeyu, "rinse poured over the body").1 The rinse helps your body adjust to the water temperature.1
The wash exists to keep the shared water clean, not as a scrub for its own sake; regulars who bathe several times a day barely soap up at all.2 What matters is that you enter the water clean.
Rinse and enter the shared bath
Enter slowly because water commonly runs 40 to 44°C.2 Ease in, stay still while your body adjusts, and give others space at the entry steps.
Where a facility has more than one tub, try the others and take cooling breaks rather than enduring one long soak.2
After soaking, you may leave mineral water on your skin, as many bathers do for its conditioning effect, or take a light tap-water rinse.21 Either choice is acceptable; the mandatory wash was the one before entering.
Pat yourself with the small towel before stepping back into the changing room.2 You do not need to be fully dry, just dry enough to keep the floor safe. Finish with the large towel at your locker.
Nudity, Towels, and Gender Separation
Communal bathing is gender separated almost everywhere, and each side runs the same routine.72 Read the curtain or sign at the entrance rather than guessing from color alone.
Full nudity in traditional baths, and where it does not apply
Traditional communal baths are entered fully nude, with no swimsuits allowed.123 Swimwear counts as an outside contaminant in shared mineral water, so wearing one where it is banned disrupts the bath as much as skipping the wash.3
That norm ends where the facility says it ends. A few commercial, theme-park style facilities are the exception, and each posts its own dress code.3 Private and en suite baths remove the question entirely because only your group uses the water.38
If nude bathing feels like too much for a first visit, book privacy rather than bending the communal rule. Do not wear swimwear into a standard bath just in case.
The small towel convention
Two towels cover the whole visit.2 The small towel goes with you into the bathing area for washing and brief modesty cover while walking. The large towel stays in the changing room for drying afterward.
At a 旅館 (ryokan, "traditional Japanese inn") or hotel, towels are usually waiting in your room or at the bath.2 At public bathhouses they are often rented or sold for a few hundred yen, and bringing your own is fine.2
Gender-separated bathing as the default
Changing rooms and nearly all communal baths are gender separated.72 Entrances are typically marked by 暖簾 (noren, "split curtain") in red for women and blue for men.
Read the kanji to be sure: 女 (onna, "woman") marks the women's side and 男 (otoko, "man") marks the men's side.72 Colors usually follow the same pattern, but they are not universal, and the characters are the reliable signal.
Mixed 混浴 (konyoku, "mixed-gender bathing") baths exist but are uncommon, surviving as a smaller tradition in some traditional and remote baths.39 Some keep full nudity while many ask bathers to wear towels or robes, so confirm the rule at that address.93
A 貸切 (kashikiri, "reserved for private use") booking lets couples and families bathe together where the communal rule would separate them.3
Tattoos: What the Rule Is and Your Options
Each facility sets its own tattoo policy, case by case.3 Treat every facility as a fresh question rather than assuming the last bath predicts the next.
Why some baths restrict visible tattoos
Many baths still bar tattooed guests.7 Social attitudes are shifting slowly and the number of onsen that accept tattoos keeps increasing, but the restriction remains common enough to plan around.13
Small tattoos in hard-to-see places are often overlooked, and international visitors sometimes receive leniency.3 Neither reaction is promised at any specific door, so neither replaces an advance check.
Three workarounds that work
Ask the facility directly before you go, by email or through your booking agency or platform.3 Some baths admit tattooed guests outside peak hours once they know in advance. A short polite message beats an anxious lobby conversation.
Cover small or medium ink with a skin-colored adhesive seal.3 Some baths sell seals at reception, and they are also sold online and at chain stores such as Don Quijote.
Book a private bath or choose a listed tattoo-friendly facility.3 A 貸切風呂 (kashikiri-buro, "private bath reserved for exclusive use") or 家族風呂 (kazoku-buro, "family bath for private group use") sidesteps shared-bath restrictions by definition.91 Searching for tattoo-friendly onsen before you travel is a practical starting point.3
Useful phrases at reception include asking whether a tattoo is acceptable, whether seals are sold and where to buy them, and whether a kashikiri bath is free.3
| Option | When it fits | What to confirm with the facility |
|---|---|---|
| Advance message | Any shared bath you have your heart set on | Whether ink is accepted, and whether off-peak timing helps3 |
| Cover seal | Small to medium tattoos that a patch can hide | Whether seals are sold at reception or must be bought ahead3 |
| Private bath | Larger ink, couples or families, or first-timer nerves | Availability, reservation method, and key handover3 |
| Tattoo-friendly listing | Travelers who want zero negotiation at the door | That the listing still matches current house policy3 |
Every row still depends on the individual facility's policy, so confirm at that address before you go.3
A thirty-second question at the front desk protects both you and the staff. Once you are inside the bathing area, every option gets harder.3
In-Bath Behavior
The shared bath rewards stillness. Enter gently, soak quietly, and keep your footprint small.
Keep the shared water clean and calm
Never submerge your head, swim, or splash.12 Keep conversation low.1 Avoid perching on the tub edge, where other bathers rest their heads.2
Tie up long hair or wrap it so it never touches the water.123 Even clean hair counts as a contaminant in shared water. Never bring soap, shampoo, or shaving foam into the bath itself.2
Leave phones and cameras outside changing and bathing areas.1 Photography there is forbidden for privacy without exception. Avoid food and drink in the bath, skip alcohol before bathing, and step out for cool water if you feel overheated.31
Private Baths When You Want Them
Many ryokan and hotels pair a communal 大浴場 (daiyokujo, "large communal bath") with private choices.38 The private side includes reservable kashikiri baths and en suite baths built into the room rate.3
A public onsen at your accommodation is usually free for overnight guests.3 Kashikiri baths usually cost extra and are reserved in advance or at the front desk, where you receive a key.3 Each house sets its own slots and house rules, so the listing decides the details.
A reservable private bath commonly costs roughly 2,000 to 3,000 yen for about 40 minutes (as of 2026-03; confirm current figures with the individual facility).9 Public sento admission is far cheaper, starting around 200 yen at small neighborhood baths and reaching 2,000 yen or more at large complexes (as of 2025-06).6
| Option | Booking | Guideline cost | As of | Who it suits |
|---|---|---|---|---|
| Public sento or day-use onsen | Walk in | Around 200 yen and up; large complexes 2,000 yen or more | 2025-066 | Solo travelers and anyone sampling bathing culture cheaply |
| Reservable private bath | Reserve ahead; fee common | Roughly 2,000 to 3,000 yen for about 40 minutes | 2026-039 | Couples, families, and bathers shy about public nudity |
Both rows move with each operator, so treat them as planning ranges and confirm the price with the facility before you go.
Day-use baths admit non-staying visitors at a fixed price in many onsen towns.31 An 足湯 (ashiyu, "footbath") near a station or town center needs no undressing at all and works as a zero-pressure introduction.3
An open-air 露天風呂 (rotenburo, "open-air bath") is often the most memorable version, whether public or private.3 Rock pools, garden settings, and waist-high screens for modesty are all common shapes.
Good to know
Confirm the tattoo rule with your facility, not with the internet
Each bath sets its own tattoo rule, so one door sticker never describes the next door.3 A blog report about one town says nothing binding about your ryokan. Message your exact facility or ask at reception before you undress.
Phones and cameras stay out of the bathing area
Photography in changing rooms and shared baths is forbidden even when the room looks empty.1 Privacy protection does not pause for an empty tub. Leave the device in the locker and enjoy the soak without documentation.
Heat and hydration catch first-timers out
Soak length depends on water temperature and your own tolerance, so keep soaks short, take cooling breaks, and drink water before and after.123 Bath water commonly runs 40 to 44 degrees, and overheating plus dehydration is the standard first-timer failure.2 Avoid alcohol before bathing and avoid bathing immediately after a meal.32
You do not need a ryokan booking to try an onsen
First-timers sometimes assume bathing requires an overnight stay at a hot-spring inn. Many onsen towns sell drop-in bathing plans to non-guests, which makes a day trip to a bath town a low-commitment first soak.1
A first-visit slip matters less than you fear
JNTO's own advice is not to be overly concerned about following every norm perfectly on a first visit.1 Review the sequence, stay aware of the bathers around you, and fix a mistake as soon as you notice it.
