Muslim Friendly Japan

Onsen for Muslims: Private Baths, Rules and Ryokan Tips

Last checked: 5 Nov 2026

Yes, there are good options for onsen for Muslims in Japan. Regular public baths are single-sex and everyone bathes fully naked. If that is not for you, you can still enjoy hot spring water in a private bath you reserve (kashikiri-buro), a ryokan room with its own bath, a free foot bath, or a facility where swimwear is required. This guide explains how onsen work, how to choose the option that fits your comfort level, and what to know about meals, prayer and wudu when you stay at a ryokan.

Onsen for Muslims: how a Japanese onsen works

An onsen is a bath filled with natural hot spring water. JNTO explains that a true onsen must use a good share of natural geothermal water, while a sento is a public bath with ordinary heated water. You will also see the words rotenburo (open-air bath) and ashiyu (foot bath).

The basic rules

According to Japan's national tourism organisation (JNTO):

  • Baths are separated by gender. Most public baths are split into men's and women's sides, usually marked with blue and red curtains. Mixed baths exist, but they are hard to find.
  • You bathe fully naked. JNTO says full nudity is mandatory at almost all hot springs. Swimsuits are not allowed in normal onsen, to keep the water clean.
  • You wash first. You sit on a small stool at a shower station and wash your whole body before you get into the bath. Make sure no soap is left on you, and rinse the stool and basin for the next person.
  • The small towel stays out of the water. You can carry a small towel, and using it to cover yourself while you walk around is optional. It must never go into the bath; people leave it at the edge or fold it on their head.
  • Hair stays out of the water. Tie up long hair, and do not put your head under the water.
  • Keep it short. JNTO suggests about 30 minutes at most, and eating and drinking in the bath is discouraged.

Lockers or baskets are provided for clothes and valuables. Leave jewellery in the locker, because some mineral waters can discolour metal.

Is a public onsen right for you?

This is a personal decision, and Muslim travellers make different choices. Some are comfortable in a single-sex bath and keep their small towel with them while they walk to the water. Many others prefer not to be undressed in front of anyone, even people of the same sex, and choose one of the private options below instead.

The water, the views and the relaxation are all available in private settings; you just need to book ahead.

Private onsen in Japan: options for privacy and modesty

1. Reserved private baths (kashikiri-buro)

A kashikiri-buro is a bath you reserve for yourself or your family for a fixed time. Many ryokan and some public bath houses have them. JNTO notes that they usually come at an extra cost and must be booked in advance or at the front desk, where you are given a key. Rentals are usually in 45 to 60 minute slots.

For a family or couple, this is often the most comfortable way to try an onsen: nobody else comes in, and tattoos are not an issue.

When you book, ask:

  • Is there a private bath (kashikiri-buro) and how much does it cost?
  • Can it be reserved before arrival, or only at check-in?
  • How long is each slot, and what times are free?

A simple Japanese phrase: "Kashikiri-buro wa arimasu ka?" ("Do you have a private bath?"). Our useful Japanese phrases guide has more.

2. A ryokan room with its own bath

JNTO's ryokan guide says ryokan rooms commonly come with tatami floors, futon bedding and sometimes a private bath, which can even be outdoors. Some rooms have a private open-air bath on the balcony, filled with hot spring water. JNTO notes that an en-suite private onsen is sometimes included in the price of the room.

This is the most private option: you bathe when you like and can pray in the same room afterwards. It costs more than a standard room, so compare prices and read the room description carefully: "private bath" sometimes just means a normal bathroom, not hot spring water.

3. Foot baths (ashiyu)

A foot bath lets you enjoy hot spring water without undressing at all. You roll up your trousers, sit on the edge and put your feet in. Several towns in this guide have free foot baths in the street or beside bath houses, so they are easy to fit between prayers and sightseeing. Bring a small towel to dry your feet.

4. Swimwear-allowed hot spring facilities

A few theme-park style facilities let you bathe in a swimsuit. The best known is Hakone Kowakien Yunessun in Hakone. Its official guide says swimwear is required in the Yunessun area, and swimwear can be rented. It also has a separate traditional area, Mori no Yu, where swimwear is not allowed. Check which area your ticket covers.

Remember that swimwear areas are mixed: men and women use the same pools. Think about whether you would be comfortable with that. Yunessun's guide does not say which styles of swimwear are allowed, so if you plan to wear full-coverage swimwear (such as a burkini), contact the facility before you go.

In Yufuin, JNTO lists Kua-ju Yufuin as a swimsuit-only bathing facility.

5. Sand baths in a yukata

At a sand bath, you are covered with warm volcanic sand while wearing a yukata (cotton robe). JNTO describes the experience at Ibusuki in Kagoshima: you change into a yukata, lie on the beach while staff cover you with warm sand, stay about 10 minutes, then wash and soak in the indoor bath. Beppu has sand bathing too: JNTO mentions Hyotan Onsen, where visitors in yukata are buried up to the neck in warm sand. The robe makes this a gentle first step, though the washing and soaking afterwards follow normal bath rules.

Tattoo rules at onsen

Many onsen still refuse guests with tattoos, because tattoos were historically linked with crime. JNTO describes the situation as very case-by-case. If you or someone in your group has a tattoo, you have three options:

  • Choose a tattoo-friendly bath. Our site notes that Kin no Yu in Arima is tattoo-friendly. In Kinosaki, the official tourism site says all of the town's public bath houses allow tattoos.
  • Cover small tattoos. Some onsen sell skin-coloured cover-up stickers. At Yunessun, tattoos must be covered, and in the swimwear area they must be fully covered by swimwear or a rash guard.
  • Book a private bath. In a kashikiri-buro or in-room bath, nobody else sees you.

Famous onsen towns and what official sources say

Arima Onsen (Hyogo), near Kobe

Arima's best-known public bath, Kin no Yu, is known for its "golden" water. The official site describes it as an iron-rich, strongly saline spring.

Useful facts:

  • Men and women bathe separately (Ichi no Yu and Ni no Yu).
  • Kin no Yu is tattoo-friendly.
  • There is a free footbath beside the building, so you can try the water without undressing.
  • You need a towel for bathing, and you can buy one inside. Body soap and shampoo are provided.
  • The official site lists opening hours of 8:00 to 22:00, closed on the 2nd and 4th Tuesday of the month. Check the official site before you go, as hours and prices change.

For prayer, Kobe's official tourism site lists prayer spots in the city, including the KICC centre with a washbasin and a tub for washing feet, and a prayer room in the Mt. Rokko area that can be used on request. See all prayer rooms in Hyogo and prayer times in Hyogo.

Hakone (Kanagawa)

Hakone offers lake views, the volcanic valley of Owakudani and many ryokan. It is also where you find Yunessun, the swimwear facility described above.

Things to know:

  • At Owakudani, the official tourism site advises extra caution because of volcanic gas for people with asthma, breathing or heart problems, pregnant women, babies, young children and the elderly.
  • The famous black eggs are ordinary hard-boiled eggs cooked in hot spring water; only the shell turns black.
  • Hakone has no restaurants specifically for halal diets, but many will accommodate dietary needs if you ask, and some offer halal options if contacted in advance.

Check prayer times in Kanagawa before you set off, as you may be on mountain transport for a long time.

Kusatsu Onsen (Gunma)

JNTO says Kusatsu has the largest amount of naturally occurring hot spring water in Japan. The water comes out at around 55°C and is cooled in wooden channels at the Yubatake ("hot water field") in the town centre. It is highly acidic and considered good for the skin.

At Netsunoyu hall near the Yubatake, you can watch yumomi: workers cool the water by turning it with long wooden boards while singing a folk song. Sainokawara Park, reached by a lane from Netsunoyu, has hot spring water flowing naturally through it.

Kusatsu has no train station. JNTO suggests a direct bus from Shinjuku, or the train to Naganohara-Kusatsuguchi Station followed by a 25-minute bus. Plan your prayers around the journey and check prayer times in Gunma.

Beppu (Oita)

Beppu is famous for its steam, and for its "hells" (jigoku): colourful hot springs that are for viewing, not bathing. JNTO notes they can reach around 99°C. There are seven hells, five in the Kannawa district and two in Shibaseki.

Useful details from JNTO:

  • You can buy a pass for all seven hells or pay at each one. Check current prices on the official site before you go.
  • Jigoku-mushi is a local way of cooking food in hot spring steam. At one facility you can buy ingredients and steam them yourself, which lets you see exactly what goes into your meal.
  • Beppu also has a sand bath at Hyotan Onsen, done in a yukata.

For prayer, Oita Airport has a prayer room on the 1st floor next to the JAL counter. Ask at the general information desk; two prayer mats are available. See prayer times in Oita.

Yufuin (Oita)

Yufuin is a quieter town near Beppu. JNTO describes it as carefully planned to keep its character, with galleries and workshops. Lake Kinrinko is fed by both hot and cold springs, and early mornings can be misty.

For modest bathing, JNTO notes that there are several foot spas around town that anyone can use for free, and that Kua-ju Yufuin is swimsuit-only. Some ryokan outdoor baths are open to non-guests for a fee, so ask whether one can be reserved privately.

Noboribetsu Onsen (Hokkaido)

Hokkaido's official tourism site says Noboribetsu has a rare variety of nine mineral-rich waters in one area. At Jigokudani (Hell Valley), boiling water and steam rise from the rocks.

The best modest option here is the Oyunuma River Natural Footbath, next to Taisho Jigoku on the Oyunuma River trail. It is free, according to the Noboribetsu tourism association, and you soak your feet in warm river water in the forest. Noboribetsu is about 15 minutes by bus from JR Noboribetsu Station and about 60 minutes by car from New Chitose Airport, which has prayer rooms for men and women with a small ablution area. See prayer rooms in Hokkaido.

Kinosaki Onsen (Hyogo)

Kinosaki is a town built around seven public bath houses, and the official site has tips for strolling between them in yukata. The official Visit Kinosaki site says the baths are separated by gender, require bathers to be naked, and all allow tattoos.

If you stay overnight, your accommodation usually gives you a pass for the public baths; day visitors can buy a day pass at any bath house. Each bath has its own closing day, and some close for renovation from time to time (Satono-yu has been closed since April 2024), so check the official site before you go. If public bathing is not for you, look for a Kinosaki ryokan with a private bath and enjoy the yukata stroll without bathing in public.

Dogo Onsen (Ehime)

Dogo Onsen in Matsuyama is a historic bath house. The official site asks visitors to check for temporary closures of Dogo Onsen Honkan due to conservation and repair work.

Dogo has one of the best private options of any famous onsen. At the annex, Asuka-no-Yu, the 2nd floor has two Special Bathing Rooms, private baths modelled on the Honkan's imperial bath, with a family-style plan. The official site says:

  • They must be reserved, online up to 90 days ahead.
  • You can wear a yucho bathing robe.
  • Soap is not allowed in the special rooms, so you wash on the 1st floor first.
  • Bathing and resting together are limited to 90 minutes.

The 1st floor of Asuka-no-Yu also has large baths and open-air baths, which the Honkan does not have. Matsuyama Airport has a prayer room. See prayer times in Ehime.

Jigokudani Snow Monkey Park (Nagano)

The famous "snow monkeys" bathe in hot spring pools in the mountains. These pools are for the monkeys, not people. Nagano's official tourism site notes that humans can enjoy an onsen at a ryokan across the river, and that the park is just upriver from Yudanaka and Shibu Onsen.

Plan carefully:

  • The park is about a 30-minute walk on an unpaved path from the parking lot or bus stop, so plan prayer times around the round trip.
  • The monkeys use the hot spring baths from December to March.
  • Hiking shoes are recommended in summer, snow boots in winter, and simple crampons are advised for winter visits.
  • Selfie sticks are prohibited, and you should watch the monkeys from a distance.
  • Nagano's tourism site lists hours of 8:30 to 17:00 in summer and 9:00 to 16:00 in winter. Check the official site before you go.

Check prayer times in Nagano and allow time for the walk back before sunset in winter.

Muslim friendly ryokan: meals, prayer and wudu

With some preparation, a night at a ryokan works well for Muslim travellers.

Kaiseki meals: ask about pork, alcohol and mirin

JNTO says a ryokan stay typically includes a kaiseki dinner (a formal multi-course meal) and a Japanese breakfast, served either in a dining room or in your room. The menu is seasonal and set by the kitchen, so you cannot simply choose dishes on the night.

The main concerns are not always obvious:

  • Alcohol in cooking. JNTO points out that cooking sake and mirin (sweet cooking sake) are used in many Japanese dishes. Some miso also contains alcohol unless it is additive-free (mu-tenka).
  • Pork and pork-derived ingredients. Ask about pork itself, and also lard and gelatin.
  • Shared kitchens. Even places that call themselves halal-friendly may not have a separate halal kitchen.

The answer is to ask in advance, in writing, when you book. Kaiseki menus are planned before you arrive, so a request on the day may be too late. As an example, JNTO mentions a Kyoto hotel that asks for two days' notice for Muslim-friendly meals.

JNTO's Muslim Services Inquiry Sheet is a bilingual form you can send or show to staff. It covers non-pork dishes, alcohol- or mirin-free dishes, seafood or vegetarian meals, separate cooking tools and tableware, and removing alcohol from your room. Many Muslims choose to ask for a seafood or vegetable-based menu cooked without alcohol or mirin; if the ryokan cannot do that, consider a room-only plan and eating elsewhere. Our guide to reading food labels in Japan helps with snacks and drinks.

Praying in a ryokan room

A tatami room is often one of the easiest places to pray in Japan. Shoes are left at the entrance, the floor is clean, and rooms are usually spacious.

Practical tips:

  • Find the qibla before you arrive with a compass app. JNTO's inquiry sheet also lets you ask whether the ryokan can lend a compass showing the direction of Mecca, a prayer mat, a copy of the Quran, or prayer clothes for women.
  • Plan around staff visits. At many ryokan, staff may come into the room to serve dinner or lay out the futons. Ask what time they will come so you can pray before or after, and tell them politely if you need a few minutes undisturbed.
  • Ask about a prayer space. JNTO notes that some hotels and ryokan offer prayer mats, qibla directions and mosque information.

For prayer rooms outside your accommodation, see our guide on how to find a place to pray in Japan and the list of mosques in Japan for visitors.

Wudu and bath etiquette

Hot spring areas usually have plenty of water, but shared washrooms still need care:

  • Make wudu in your room when you can, if it has a washbasin or bathroom. An in-room bath makes it even easier.
  • Do not make wudu in the onsen tub. The bath water is shared and must stay clean; only washed bodies go in.
  • At a shared washbasin, washing feet in the sink may surprise other guests. If you must, wipe up all water afterwards. A small cup or bottle helps.
  • Keep the changing room floor dry. Dry yourself with your small towel before you step back into the changing area.
  • Bring slip-on shoes. You will take them on and off often.

Timing your bath around prayer

Public baths often have long hours. For example, the official sites list 7:00 to 23:00 for most Kinosaki bath houses, 6:00 to 23:00 for the 1st floor of Asuka-no-Yu, and 8:00 to 22:00 for Kin no Yu, so you can usually fit a bath between prayers. A private bath is booked in fixed slots, so choose one that does not clash with Maghrib or Isha. Check our prayer-times page for the area before you book your slot. In winter, the gap between Asr and Maghrib is shorter, so a morning or after-Isha bath is often easier.

Frequently asked questions

Can Muslims go to an onsen in Japan?

Yes. Many Muslims enjoy onsen, and how they do it depends on personal comfort. Public baths are single-sex but fully naked, so many Muslims choose a private reserved bath, an in-room bath at a ryokan, a foot bath or a swimwear facility instead.

What is a kashikiri-buro?

It is a private bath you reserve for a fixed time, usually 45 to 60 minutes, for yourself or your family. JNTO notes that most charge a fee and need booking in advance or at the front desk. You get a key, so nobody else can come in.

Can I wear a swimsuit or burkini in an onsen?

Not in a normal onsen: swimsuits are not allowed. A few facilities, such as Yunessun in Hakone, require swimwear in their mixed area. Contact the facility first if you plan to wear full-coverage swimwear, as rules on styles are not always published.

Can women wear a hijab in an onsen?

Normal public baths do not allow swimwear or clothing, and towels must stay out of the water. Women who want to stay covered usually choose a private bath, an in-room bath, a foot bath or a swimwear facility, after checking its rules.

Will a ryokan prepare a meal without pork and alcohol?

Some will, but only if you ask in advance. Send your request in writing when you book, and use JNTO's Muslim Services Inquiry Sheet to explain no pork, no alcohol and no mirin. If the ryokan cannot confirm, book a room-only plan.

Where can I find a free foot bath?

Several famous onsen towns have them. Our site notes a footbath beside Kin no Yu in Arima, JNTO mentions several free foot spas in Yufuin, and Noboribetsu has the free Oyunuma River Natural Footbath.

Can I visit an onsen if I have a tattoo?

It depends on the facility. Kinosaki's official site says all its public bath houses allow tattoos, and Kin no Yu in Arima is tattoo-friendly. Elsewhere, cover small tattoos with stickers where allowed, or book a private bath.

Plan your onsen trip

An onsen trip can be relaxing and fully in line with your comfort: choose a private bath or an in-room bath, ask about meals early, and plan your prayers around bath slots and travel. Before you go, check prayer times in Hyogo, Oita or Kanagawa, read how to find a place to pray in Japan, and save our useful Japanese phrases for talking to ryokan staff.
