This is a unique and special place among the hot springs near Lake Kussharo. As you can see from the name, there is a hot spring in the sand on the shore of the lake. People take pleasure in digging the sand and making their own bathing pools. However it is located in a crowded and popular sightseeing spot and bathing suits are required. In fact, most people just enjoy Ashiyu, a spa for the feet, because it is quick and easy.
