Heisei no Yu, in Ono (Fukui prefecture), near the Kuzuryu river, heats iron-rich water to 38°C. An indoor bath, an outdoor rotenburo bath, and a sauna come together in this mountain setting.
Insider tip — Kuzuryu Onsen Heisei no Yu takes its name from the Kuzuryu River valley cutting through the mountains of Fukui, where iron-rich groundwater seeps from ancient sedimentary rock. The amber-colored bath water is recognized for stimulating blood flow and easing joint stiffness, drawing visitors from across the Hokuriku region. Heisei no Yu's relaxed pace and traditional architecture reflect the rhythms of a small mountain community still shaped by forestry. The journey through the narrow valley road is itself a highlight of the visit.
