Yong Ye Wenquan is located in Ube, Yamaguchi Prefecture, Japan. This sulfurous spring, warm at around 45°C, feeds an indoor bath, a rotenburo-style outdoor pool and a sauna.
Insider tip — Located in western Honshu's Yamaguchi Prefecture, this onsen draws from a geothermal system associated with the Chugoku volcanic arc remnants. The high temperature of 45°C demands a gradual approach — experienced bathers alternate brief immersions with cool-down rests. The sulfurous character is pronounced, and regular bathers attest to benefits for skin conditions. The industrial city of Ube surrounds it, but the onsen itself offers a traditional retreat from urban life.
