Yuda Onsen Ekimae Ashiyu (Hakuko no Yu) is located in Yuda Onsen, a hot-spring town in Yamaguchi Prefecture. Its sodium-chloride thermal water is notably hot, at 48°C (118°F). An indoor bath, an outdoor rotenburo bath and a sauna are available.
Insider tip — Yuda Onsen's founding legend involves a white fox (hakuko) soaking its injured leg in a spring and recovering — the fox's healed white fur gave the spring its name. Every November the Yamaguchi Yuda Onsen White Fox Festival celebrates this legend. Yuda is one of the few Japanese onsen stations where the spring source bubbles directly under the train platform; 'Hakuko no Yu' (white fox spring) ashiyu at the station entrance lets rail travelers sample the highly alkaline (pH 9.0) waters before boarding — famously softening skin in minutes.
