Kyodo Yokujo, home to Kawarayu Onsen, is located in Kokonoe, Oita Prefecture. Its sodium-chloride water reaches around 41°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Kawarayu Onsen' (河原湯 — riverside hot spring) Kyodo Yokujo (公共浴場 — public bath) in Kokonoe-machi, near the confluence of mountain rivers feeding the Yamakuni system. The riverside public bath is one of Japan's oldest bathing traditions — thermal springs emerging along riverbanks, where the geological energy of mountain uplift meets the surface. In Kokonoe, where the Kuju volcanic system heats both the highland meadows and the valley floors, the riverside bath is a direct expression of the earth's thermal generosity.
