Introducing Towada-ko

Formed by a series of violent volcanic eruptions, Towada-ko is a roughly circular caldera lake hemmed in by rocky coastlines and dense forests. Part of the Towada-Hachimantai National Park, it is the largest crater lake in Honshū (52km in circumference).

It is rivalled in beauty by the Oirase-gawa, the winding river that drains Towada-ko into the Pacific Ocean. The recent extension of the shinkansen (bullet train) to Aomori Prefecture put the area within easy striking distance, yet development around the lake remains sparse, save for the main tourist hub of Yasumiya.
