Onsen options for travellers who prefer privacy

You can enjoy a hot spring in Japan without bathing with strangers. Choose a room with its own bath, or reserve a private bath for your group. Confirm the option in writing before you book, because some inns have only shared baths.

What privacy options exist?

Ryokan and onsen hotels offer several levels of privacy. Private baths, sometimes outdoor, are common elements of a ryokan stay, and most ryokan have an onsen ¹. The details vary by inn, so ask what each one actually provides.

From most private to least:

1. A bath inside your guest room, used only by your party.
2. A private bath you reserve for a time slot, called kashikiri.
3. A shared bath at a quiet hour, separated by gender.
4. A shared bath at the busiest hour.

What is an in-room bath?

An in-room bath belongs to your room, and sometimes sits on a private terrace. You soak when you like, with no booking and no strangers. It is the easiest choice for couples, families and modest travellers.

Rooms with their own bath usually cost more than standard rooms, and they sell out first. Read our guide on private open-air bath rooms for what to ask.

What is a kashikiri private bath?

A kashikiri bath is a private bath that you reserve for a set time. It suits families who want to bathe together and travellers who want cover but do not have an in-room bath.

Time slots, rules and any fee vary by inn. Ask whether you book on arrival or in advance, and how long the slot lasts.

What should you check before booking?

Write the answers down, since staff can change.

• Does the room have its own bath, and is it indoor or outdoor?
• Is there a private bath to reserve, and how is it booked?
• Are shared baths gender-separated, and used without swimwear?
• Can children soak with a parent, and at which ages?
• Is the bath cleaned and accessible to elders?

Our what to ask before booking a ryokan and Muslim-friendly requests to confirm lists help with the wording.

What if a shared bath is the only choice?

You can still enjoy the stay without using it. Some travellers shower in the room and skip the bath. If you wish to try the shared bath, go at a quiet hour and read onsen etiquette for first-timers so you know the steps.

JNTO says Japan is tolerant of different religions and is becoming more attuned to the needs of Muslim visitors ². Ask politely, and most inns will tell you plainly what they can offer.

How do you pick a stay?

Put privacy first when you search. Choose a ryokan or hotel that lists a room bath or a bookable private bath. See ryokan versus hotel with onsen and the onsen-ready stay checklist to prepare.
