Set in Okuizumo, Shimane Prefecture, Hinokami Onsen offers thermal sodium-chloride water at 40°C. The facility combines an indoor bath, an open-air rotenburo and a sauna.
Insider tip — Okuizumo (奥出雲 — deep Izumo) is the heartland of Japan's legendary Tatara iron-smelting tradition — the Chugoku Mountains provided iron sand (satetsu) for three-day continuous furnace smelting that produced tamahagane steel from which samurai katana are forged. The Nita Iron and Steel Museum demonstrates this living craft. 'Hinokami' (火神 — fire god) Onsen's name perfectly captures the fiery heritage of a region where volcano-forged iron and divine fire have been intertwined for centuries; nearby Izumo Taisha Grand Shrine adds spiritual depth.
