Lake Jusan

Lake Jusan is the third-largest lake in Aomori Prefecture. It stretches 7 km from north to south and 5 km from east to west. The circumference is 31.4 km. It is called Lake Jusan because 13 (read 'jusan') rivers flow into this lake. It is a brackish water lake blessed with abundant natural resources, and a home to Asian clams. The area around the lake flourished as a port city between the Kamakura and Muromachi periods (12th to 16th centuries), and the Tosaminato (Tosa Port) ruins tell us about life in the area at that time.
