🌋 Lake Kussharo Sunayu (Hokkaido)

On the eastern shore of Lake Kussharo, Japan’s largest caldera lake, lies another unique Sunayu experience. Here, visitors can dig into the sandy beach to create their own personal hot spring bath, as geothermal water seeps up through the sand.   Highlights: • Create your own open-air bath by digging in the sand.  • Footbaths are available for those who prefer a more relaxed experience.
