About

A ryokan right on the Kochi coast, with indoor baths and an open-air bath drawing from a faintly salty, slightly cloudy spring that leaves skin noticeably smooth. A free foot bath sits outside the entrance. The building has an old-fashioned feel, with Henro pilgrimage decor and Showa-era touches that give it more character than a plain hotel. Day-use bathing is available.
