Kawayu Onsen Hot Spring

A giant open-air public hot spring bath is open for free. Located on the riverbank, the large bath is a genuine natural onsen; the cold river water helps cool the hot-spring water of about 73-degrees celsius, and creates onsens that are around 40-degrees celsius. On Saturday evenings, the area will be illuminated by lanterns. Make sure to bring a swimsuit for bathing.

Time: 6:30am–10pm
Admission: JR Shingu Stn, bus to Kawayu Onsen
