Satono-Yu is the largest of the seven public onsen in Kinosaki Onsen and offers the most comprehensive bathing experience. Unlike smaller facilities, it features multiple bath types including indoor baths, an upper-floor rotenburo (open-air bath), and a sauna. The facility also has a unique dual-section design with both Western-style Turkish baths and traditional Japanese-style baths that rotate between men and women, allowing visitors to experience both styles during their stay.
