About
A day-use onsen built in a traditional Japanese single-story style, with reclaimed timber from old farmhouses worked into the beams, ceiling, and walls throughout. The hinoki (cypress) indoor baths and rotenburo (open-air baths) run with clear, lightly saline spring water renewed on site in 2021. Sauna and cold bath are available in both men's and women's sections, and three private rooms each have their own open-air bath, bookable by phone.
