Imajo 365 Onsen / Yasuragi is located in Minami-Echizen, Fukui Prefecture. Its sodium-chloride water, at 41°C, feeds an indoor bath and an outdoor rotenburo, with a sauna rounding out the facility.
Insider tip — Imajo 365 Onsen Yasuragi, open every day of the year, sits astride the ancient Hokuriku highway (Hokkoku Kaido) that carried silk, lacquerware, and imperial tribute from Kaga and Echigo to the Kyoto court across the Imajo mountain pass. The 365-day name reflects both the year-round hot spring philosophy and the historic role of Imajo as an all-seasons transit point between the snowy Sea of Japan coast and the Kinai heartland.
