This Onsen Bathhouse was built around a rocky hill where a hot spring occurs, therefore it has a natural stone wall on the first floor with natural spring water fountains seaping through the rocks and filling up the indoor hot spring bath, it also features a tea room and a meditation hut perfect to relax and prepare for mountain expeditions.
