A blissful hot spring experience awaits you at Kobu Onsen, situated in the Niseko region of Hokkaido, one of Japan’s top outdoor adventure spots. Known for its mineral-packed, naturally heated waters, Kobu Onsen provides a relaxing retreat after a day of skiing, snowboarding, or hiking in the Niseko mountains. The onsen facilities here often feature outdoor baths (rotenburo) with breathtaking views of the surrounding landscapes, including Mount Yotei, known as the “Fuji of Hokkaido.”
