Kotan no Yu:
A free open-air hot spring
by Lake Kussharo

This natural open-air hot spring bath will make you feel like you’re bathing in Lake Kussharo itself

This hot spring bath surrounded by stones is just 5m from Lake Kussharo, creating the illusion that you are bathing in Lake Kussharo itself. In winter, the warm water runs into the lake, attracting swans that you can see right before your eyes. As you look out over the lake, you'll feel as if the swans are bathing in the hot spring with you. This vast natural paradise is stunningly beautiful no matter what time of day you visit, with incredible sunsets over the mountains beyond the lake and stars as far as the eye can see at night. Admission is free and free parking is available. Basic men's and women's changing facilities are available. The bath is surrounded by stones. While there is a large stone in the center dividing the bath in two, each side is visible from the other side, so bathing is basically mixed. Swimwear is OK.
