About

This is a large resort hotel attached to a golf course in the hills of Koka, with its own hot-spring bathing facility, Koka Onsen Yappon Pon no Yu, open to day-use guests as well as those staying overnight. The main draw is the open-air rotenburo, a rock-lined bath with mountain views, plus an indoor bath and a rock-bed bath (ganbanyoku) and a sauna heated with fragrant stone. Two private family baths can be booked by the hour. Rooms range from Japanese-style to Western twins and suites, and the hotel runs a yakiniku restaurant on site.
