Lake Akan
Lake Akan is Hokkaido's fifth largest freshwater lake and is known as a habitat for marimo moss balls. Marimo moss balls can be found in freshwater lakes all over the world, but the ones in Lake Akan have international significance due to their beautiful spherical shape with a diameter of more than 15 cm.
The water here is so clear and beautiful. You can't see the marimo from the lakeshore, though.
