Lake Kussharo Sunayu Onsen
Dig Your Own Hot Spring on the Shores of Lake Kussharo
A unique hot spring experience on the shores of Lake Kussharo. Dig into the sand to create your own natural pool and enjoy the earth’s warmth.
Located on the eastern shore of Lake Kussharo within Akan-Mashu National Park, Sunayu is a rare geothermal attraction. Dig a short distance into the sandy beach and warm spring water naturally rises to the surface. Rich in sodium bicarbonate, the smooth waters create a memorable place to relax.
The experience is enhanced by sweeping views of Lake Kussharo, where the water shifts from deep blue to emerald depending on the season and sunlight. Gentle waves and the surrounding wilderness create a peaceful atmosphere.
Sunayu offers a different experience throughout the year. In summer, visitors can enjoy both the cool lake and warm sand pools. In winter, geothermal heat keeps parts of the shoreline ice-free, attracting whooper swans from Siberia. Watching these elegant birds among rising steam and snowy scenery is one of the area’s highlights.
