The mountain forms a major part of the Higashi Daisen mountain range and stands at an elevation of 615 meters. The summit is a broad, flat lava plateau, but the upper slopes to the east, west, and north are lined with nearly vertical cliffs. It is an ideal spot for hiking and mountain climbing, taking approximately 40 minutes to reach the summit. It is also the place where Emperor Go-Daigo's Kenmu Restoration started and has been designated as a national historic site. The mountain is included in Japan’s list of the 100 best spots for autumn foliage. It has also been designated as Daisen-Oki National Park.
