About

Rokko no Yu is a day-use hot-spring bath attached to a hotel in Kamisu, reached through a connecting corridor from the main building. The water is salty and mineral-rich, filling an outdoor rotenburo, a small round tsuboyu (つぼ湯) pool and an indoor bath, alongside a large sauna and a cold plunge. There is a resting area and a dining hall for after the bath. Tattoos are not allowed in the bathing area.
