History

Geologically, the mountain rests on a basement of Neogene sandstone and tuff, overlain by dacitic welded tuff that erupted and accumulated around the beginning of the Quaternary period. This welded tuff layer extends about 10 kilometers to the northwest, reaching the Komado Plateau where the Komado Marsh lies. It is counted among lists such as the 300 Famous Mountains of Japan, the 100 Famous Mountains of Tohoku, the New 100 Famous Mountains of Utsukushima, and the 100 Famous Mountains of Aizu.
