Lake Akan
About This Destination
Lake Akan is a volcanic caldera lake renowned for its mysterious marimo, rare spherical green algae colonies that grow naturally only here and in a few other places worldwide. The lake's crystal-clear waters and surrounding virgin forests provide habitat for diverse wildlife including the endangered Blakiston's fish owl. Visitors can explore by boat, soak in lakeside hot springs, and experience the rich Ainu culture at the adjacent kotan village.
