GanbanyokuAbout
The hotel's open-air bath sits up on the building, looking straight out over the Pacific, and the indoor bath (marble and wood) shares the same ocean view along with a night sky when it's clear. The water is a sodium chloride spring, salty and kept on the mild side rather than piping hot, with a smooth, silky feel on the skin. There's also a sauna, and a separate poolside area with a cold rock bath. Baths are split by gender, swapped once overnight, and are for hotel guests only.
