A day-use hot spring facility located at the southern entrance to Yuda Onsen in Yamaguchi Prefecture, an area famous for the legend of the white fox.

On the second floor, the facility offers a restaurant, esthetics, body care and an ashiatsu treatment area, a bedrock bath, and a manga corner, making it a full-scale bathing complex that never gets boring even during a long stay.

Hot Spring & Bath Information

Bath

TypeNatural Hot Spring

An open-air bath built with natural rocks, where you can fully enjoy the alkaline simple hot spring of Yuda Onsen. Two waterfall showers are installed, allowing you to direct the stream onto your shoulders and neck to ease physical fatigue. Thanks to the abundant supply, the fresh water flows in clear and colorless, creating a silky skin feel characteristic of its highly alkaline pH 9.1 water. The outdoor relaxation area for after sauna use is also located around this open-air bath.
