This return route follows the rim of the Mashu caldera from Lake Mashu First Observatory to the 857-metre summit of Mount Mashu, also known as Kamuinupuri. The ridge offers recurring views of Lake Mashu and seasonal alpine flowers, while the steep final climb leads to views of the explosion crater and the mountains toward Akan and Shiretoko.
