Each guide is written for travellers, not insiders, and sticks to general information that holds across Japan. Where rules vary between properties, as they often do for tattoos, children and private baths, we say so and point you to our listings, where every fact links to the official website it came from.

Not sure where to start? Read onsen etiquette for first-timers and private onsen vs in-room bath vs family bath first, then browse onsen towns or the tattoo-friendly list.
