×Somewhere to sit — Bathe and leave
△Anything else nearby — Nearby, but off to one side

A ninety-year-old wooden bathhouse that is a genuine landmark of Koenji and still the neighbourhood's daily bath, ten minutes by train from Shinjuku. It is ordinary heated water, indoors only, and once you are dressed there is nowhere inside to sit.

Every onsen on this site is scored against the same written rubric. This score has been reviewed by the editor. The ones marked Visited were also bathed in personally.

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

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.

What we have not confirmed

We would rather show a gap than guess.
