Kotan-no-Yu Hot Spring
Soak in Golden Sunsets and Encounter Winter Swans at This Lakeside Retreat
Experience a profound sense of unity with nature at this rustic open-air bath, where the hot spring waters seem to merge seamlessly with the vast surface of Lake Kussharo.
Situated right on the edge of Lake Kussharo, Kotan-no-Yu is a stone-lined open-air bath meticulously cared for by the local community. As you sink into the steaming water, your line of sight aligns perfectly with the lake’s surface. With no barriers to obstruct the panoramic view, you will feel as if you are floating within the Great Lake itself. The gentle lapping of the waves creates a soothing soundtrack, while the soft, mineral-rich water, abundant in metasilicic acid, tenderly hydrates your skin.
At dusk, the sky and lake are painted in vivid shades of gold, offering a breathtaking spectacle of light and shadow in the profound silence. During the crisp winter months, elegant whooper swans migrating from Siberia arrive at the water’s edge. Observing these graceful white birds against a backdrop of dancing snowflakes—from their very same eye level—is a quintessential Hokkaido experience. While a large central rock naturally separates the bathing areas, the use of swimwear or towels is permitted, allowing friends and families to share this liberating hidden gem together.
