Kotan no Yu
Where Hot Spring Meets Nature
Along the shores of Lake Kussharo, you will find several open-air hot springs where you can bathe for free. Among these hidden gems, “Kotan no Yu (Kotan hot spring)” is particularly famous. This secluded hot spring has been featured in many media outlets for its breathtaking views: at sunset, the lake surface glows golden, and in winter, you can see swans gracefully floating on the lake.
The spacious bath, open to the lake with a liberating atmosphere, is kept clean by local residents. While Kotan no Yu is a mixed-gender open-air bath, there are separate changing rooms for men and women. The bath itself is divided by large rocks, allowing bathers to enter wearing swimsuits or wrapped in towels if they wish. Since the water level is almost the same height as the lake surface, you will feel as if you are soaking directly in Lake Kussharo itself. The water is rich in metasilicic acid, a natural component known for its moisturizing benefits for the skin.
