Minori Onsen (Resort Center) is located in Itō, on the Izu Peninsula, Shizuoka Prefecture, Japan. Its sodium-chloride water emerges at around 42°C and feeds an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — In Itō, the Izu Peninsula spa city where Dutch merchant Jan Joosten built Japan's first European-style ship in 1604 and where the Ikenoue hot spring district has drawn Edo-era travelers for centuries, Minori Onsen (harvest spring) taps the same deep saline aquifer that made Ito one of eastern Japan's most celebrated resort destinations; the harbor atmosphere and local kinmedai golden-eye snapper cuisine complete the experience.
