How we know
A stay is listed when we have its onsen analysis report on file, or when we checked its private open-air baths, reservable private baths or tattoo rules against its official website or booking-site page. Stays with neither are left out. Lists for each onsen town are under “More onsen towns” below.
- This list includes stays whose onsen analysis report we have on file, and stays whose facility details we checked against a source. Stays with neither are left out.
- Private bath and tattoo information comes from each property's official website or other published information. Every item links to its source and shows the date we last checked it. Items we could not source are left out.
- Spring type, pH and how the water is used come from the onsen analysis report that Japanese law requires each facility to post, and from the facility's water-usage notice. They are shown only for stays whose report we have on file.
- Details can change after we check them. Please confirm with the property before you book, especially tattoo rules and private bath fees.
- Booking buttons are affiliate links. They do not affect which stays are listed.
