The Fuji Five Lakes (富士五湖, Fujigoko) are made up of Lake Kawaguchiko, Lake Yamanakako, Lake Saiko, Lake Shojiko and Lake Motosuko at the northern base of Mount Fuji.

The five lakes were formed hundreds of years ago by lava flows which dammed up rivers during Mount Fuji's multiple eruptions. Interestingly, three of the lakes, Saiko, Shojiko and Motosuko are still connected with each other by underground waterways and consequently maintain the same surface level of 900 meters above sea level.
