Located in Daisetsu National Park in the town of Shikaoi, Tokachi, the Lake Shikaribetsu is a lake in Hokkaido with the highest altitude measuring about 810 meters above sea level. It is also known as the “Lake of the Sky” since it is a great place to do stargazing at night. The whole lake is frozen in wintertime which allowed the construction of a kotan (Ainu word for village) of Eskimo-styled igloos called the Ice Village.
