Oita Onsen Monogatari Mitsukawa no Yu, in Ōita, heats its sodium-chloride water up to 43°C. An indoor bath, an outdoor rotenburo bath and a sauna are offered to visitors.
Insider tip — Oita Prefecture produces more hot spring water than any other prefecture in Japan, and Mitsukawa no Yu, the three rivers spring, draws on this extraordinary volcanic bounty. Oita city is the urban gateway to Beppu, Yufuin, and the Aso-Kuju volcanic highlands — the three crown jewels of Japanese hot spring tourism.
