Boat BathAbout
This hotel above the Inatori coast is built as much around its baths as its rooms. Two separate bathing halls hold sixteen different baths between them: an open-air bath that looks straight out over the horizon, a big indoor bath with floor-to-ceiling sea views, a walking bath, a massage waterfall, a herb bath, a lie-down bath, a rock bath, and a cave bath you follow back into the dark. There's a coral-lined sauna room with a cold plunge to go with it, and a spot by the restaurant where the spring water is safe to drink. Two private open-air baths can be booked separately, one shaped like a boat on the top floor and one right at the water's edge downstairs. The spring itself is clear and salty, close to the sea in taste. A few of the room categories add their own semi-open-air bath, fed straight from the spring rather than recirculated.
