About

A big day-use bathhouse right outside Kamihoshikawa Station, using onsen water drawn from the building's own well. Inside there are indoor tubs, jet baths, and three different electric baths; outside there's an open-air bath along with a couple of cooler tubs that people tend to settle into for a long soak. There's also a steam sauna and a tower sauna. The place is done up like an old Japanese village inside, and there's a restaurant downstairs for after your bath.
