Overview (history, characteristics, attractions)
Lake Akan is a caldera lake located in Kushiro City, Hokkaido, and is one of the main tourist destinations in Akan-Mashu National Park (an area that now includes Akan-Mashu Prefectural Natural Park). A hot spring town (Lake Akan Onsen) spreads out along the lakeside, and the area is attractive for its magnificent mountain views, including the surrounding active volcanoes Mount Meakan and Mount Oakan, as well as its primeval forests and marshland scenery.
Lake Akan is especially known worldwide for its marimo (round algae), which grow in round shapes and are designated as a natural monument. The area is also home to a strong Ainu culture, and traditional crafts and dance can be seen at the Ainu Kotan (village) on the shores of Lake Akan.
