History
Situated in Kurokawa Onsen, a picturesque hot spring village that gained fame in the 1980s and 1990s for its coordinated effort to preserve a traditional, nature-integrated onsen atmosphere. The village's rotemburo meguri (bath-hopping pass) system, pioneered by local innkeepers, became a model for onsen communities across Japan. Satonoyu Waraku embodies Kurokawa's philosophy of harmony between nature, architecture, and bathing culture.
