Kibedani Onsen; Matsu no Yu is located in Yamaguchi, Yamaguchi Prefecture. The sodium-chloride water surfaces at 41°C. The bathhouse includes an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Matsu no Yu, the pine spring, serves the Kibedani mountain valley of eastern Yamaguchi Prefecture where the Kibe River descends from the Chugoku highlands through pine-forested ridges to the Seto Inland Sea coastal plain. The eastern Yamaguchi interior preserves the remnants of the ancient Saigoku road connecting Kyushu to the old capitals, and the Kibe River valley was historically an important mountain corridor connecting the San-yo coast to the San-in Sea of Japan communities across the Chugoku mountain spine.
