Experience the mystery of the Mashu and Kussharo calderas
To the west of Akan-Mashu National Park is the Kussharo Caldera, the largest caldera in Japan, and to the east of the park is the Mashu Caldera. Within each of them is a spectacular sea of clouds that can be viewed from the caldera's outer rim. You are most likely to see the sea of clouds in June and August, but the longer you stay in the region, the higher your odds are of encountering this phenomenon.
