Kuma no Yu Hot Spring
熊の湯
A free open-air wild hot spring by a stream in Rausu Onsen, managed by local volunteers. The milky sulfur water runs hot, and men and women bathe separately.
Kuma no Yu sits across the Rausu River stream from Rausu Onsen. It is a free open-air hot spring maintained by the local Kuma no Yu Enthusiasts' Association. Men and women bathe separately, and the setting is surrounded by forest. The sulfur water runs quite hot, at about 44°C or above. The rules here require washing thoroughly before entering, using no soap, wearing no swimsuits, and taking no photos. Regulars take etiquette seriously. It is open all day, with a cleaning break in the morning. There are no changing rooms, though the women's bath has a simple shelter. It is about 5 minutes by car from Rausu town, next to the Shiretoko Rausu Visitor Center and a campground.
Opening hours
