Mount Kamui (カムイヌプリ Kamui-nupuri ^[1]), also Kamuinupuri or Mount Mashū, a potentially active volcano, is a parasitic stratovolcano of the Mashū caldera (itself originally a parasitic cone of Lake Kussharo)^[2][3][4] located in the Akan National Park of Hokkaido, Japan.

Mount Kamui rising above Lake Mashū.

Volcanism

Mount Kamui rose on the rim of 6 km-wide Mashū caldera, about four thousand years ago, after the collapse of Mashū volcano. Its last eruption took place about 1000 years ago.^[5]

Tourism

Hikers can follow a 7.2 km wooded trail to the peak of the mountain, walking along the ridge of the caldera, which is a 300-m vertical drop to the surface of the Lake Mashū, offering spectacular views.^[6]
