Kumanokawa Onsen Chidori-no-yu
熊の川温泉 ちどりの湯
A municipal day-use bathhouse in the Furuyu–Kumanokawa spa area along the Kase River, about 30 minutes by car from central Saga. Kumanokawa's water is a radon-bearing radioactive (radium) spring, traditionally enjoyed as a long, slow soak at lukewarm temperature. The main hall has large and small pools at different temperatures, an open-air bath facing the hills, and a small sauna and cold plunge, all lively with local chatter. A barrier-free family bath (¥1,500 for 55 minutes plus admission) is available, and the tatami rest room offers meals and massage. Adults ¥600, children ¥350; open 10:00–21:00, closed the 3rd Thursday (next day if a holiday). Local vegetables are sold at the front desk, and the grounds have a hot-water stand and a 'Yu YOU Park' for car camping. Pair with Furuyu Onsen for a bath-hopping day.
