Shinsoyu Onsen (Shiun no Sato) is located in Shibata, Niigata Prefecture, Japan. The sodium-chloride water reaches about 41°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In Shibata, the Niigata castle town and sake brewing center at the edge of the Echigo Plain, Shiun no Sato (purple cloud village) creates a dreamy pastoral atmosphere around its sodium-chloride spring; the surrounding cedar groves and rice paddies that feed Niigata's legendary Koshihikari rice production frame this onsen in Japan's most quintessentially agricultural landscape.
