Kumanoyu Hot Spring
Relax in a free public open-air bath in the heart of the wild
Discover Kumanoyu, a free public open-air bath nestled in Shiretoko's primeval forest. Experience a rustic wilderness retreat cherished by the local community.
Located on the banks of the Rausu River, Kumanoyu is a historic open-air bath favored by local fishermen since the Meiji era. Surrounded by the forests of the Shiretoko Peninsula, this hidden hot spring now attracts visitors from across Japan. Soaking in the rustic rock bath offers a remarkable sense of openness and a chance to connect with the surrounding wilderness. Watching the forest change through the seasons is a uniquely Shiretoko experience.
Separate bathing areas are provided for men and women, with the women's bath enclosed for added privacy and comfort. As the bath lies close to the source, the water can be quite hot at times, reflecting its natural state. Guests can relax in the rising steam while listening to the river and the calls of forest birds. Maintained by local volunteers, the bath includes a donation box to help preserve this unique community hot spring for future generations.
If you are lucky, you may even spot a Steller's sea eagle soaring overhead. Surrounded by Shiretoko's magnificent wilderness, visitors can enjoy an unforgettable hot spring experience.
