Therme Hakuryu (Kenko Onsenkan) welcomes bathers in Ōe, Yamagata prefecture, with sodium-chloride water rising at 42°C. An indoor pool, an outdoor rotenburo bath and a sauna combine for a full thermal stop in the Japanese countryside.
Insider tip — Hakuryu, the white dragon, evokes the sacred white serpent deity worshipped along the Mogami River that flows through Oe-machi. The Therme Hakuryu combines a European spa concept with Yamagata onsen heritage, and the riverside landscape here is particularly beautiful when autumn maples ignite the hills above the water.
