Furubira Onsen Shiokaze, in Furubira on the island of Hokkaido, offers sodium-chloride water at 40°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Furubira Onsen Shiokaze perches on the Sea of Japan coastline of Hokkaido, where the name Shiokaze meaning sea breeze reflects the maritime character of the setting. The sodium-chloride water at 40°C emerges from deep Cretaceous formations and carries a pleasant salinity that is said to warm the body from within, important in a coastal town lashed by winter winds. Views from the bath overlook a rocky shoreline where fresh seafood is landed daily, and the combination of a soak followed by grilled scallops is the local custom. Spring and early summer bring calm seas and stunning sunsets over the Japan Sea.
