🗺️ Lake Kussharo

Lake Kussharo, approximately 20 kilometers long from north to south, is the largest caldera lake in Japan and the largest freshwater lake that is completely frozen. The mountain Mokoto, which created Lake Kussharo, is famous for a massive volcanic eruption in ancient times, with volcanic ash that could cover all of Hokkaido. Surrounded by rich natural environments, Lake Kussharo is fed by springs, with 80% of its water source coming from these natural springs, making its water quality exceptionally well-known. It is also a popular spot for water activities such as sailing and canoeing. From the observation deck at Bihoro Pass, which is at an altitude of 525 meters, you can enjoy a panoramic view of Lake Kussharo. Additionally, Lake Kussharo is well-known for its hot springs that emerge from various locations. It is recommended to visit the free outdoor bath KOTAN no Yu, as well as the sand bath with hot spring water.

Lake Kussharo is suitable for sightseeing all year round, but some attractions may be inaccessible in winter, so please pay special attention. The lake was formed by volcanic activity, and there are several hot springs along the lakeshore. There are well-established accommodation facilities around the lake. In winter, it is famous for the many swans that gather there.
