How it scores
Every onsen on this site is scored on the same five things.
The baths
Indoor bath
Two indoor baths, 'Kinsen-no-yu' (capacity 10) and 'Megumi-no-yu' (capacity 5), swapped between men and women. Staying guests 13:00 to 10:00 next morning (closed 0:00-5:00); day visitors 13:00-20:00 (last entry 19:30). The official site states there is NO public open-air bath here.
Private (kashikiri) bath
One private family bath (indoor), built from marble imported from Italy in 1917. FREE of charge for staying guests. Reservation required for 15:00-23:00, taken same-day at the front desk on a first-come basis only (NO advance booking); no reservation needed 5:00-9:00. Day-use availability is not stated.
In-room bath
SOME rooms only have a private open-air bath (Japanese-style rooms with open-air bath, standard and small); other categories have a view bath, an indoor bath, or no bath at all.
Indoor bath
Historic ryokan founded in 1630 on the Haya River.
Open-air bath
Open-air baths along the mountain stream.
In-room bath
Guest rooms with private open-air baths, for overnight guests only.
A private bath means nobody else is in the water with you — often the practical answer if the shared baths are closed to tattooed guests.

Book it
The links below are affiliate links — we may earn a commission if you book through them, at no extra cost to you. It never changes what we list or how we score it.
Why Agoda for Japan: it lists a lot of ryokan and small inns that the Western booking sites never picked up, and it usually prices Japanese properties in yen, so you are not paying a conversion spread on top of the room rate. Worth comparing before you book — the difference on a ryokan is often larger than you would expect.
About the day-pass link: Asoview is the main place day-use onsen in Japan sell entry tickets and discount coupons in advance. It is a Japanese-only site, so use your browser’s translation — you show the ticket on your phone at the door.
Getting in from the airport
The links below are affiliate links — we may earn a commission if you book through them, at no extra cost to you. It never changes what we list or how we score it.
Why not the train: the last leg to an onsen is usually a local bus with nowhere to put a suitcase. A fixed-price car is booked in English and quoted before you travel, tolls and fuel included.
