Mt. Daisen is a volcanic mountain located in Tottori Prefecture, Sanin Region of Japan. It is the highest in the Chugoku region with an elevation of 1,709 meters. In addition to the colorful changes of four seasons, Mt. Daisen changes its shape vastly depending on which side of the mountain the viewer is standing on.

It is designated a national park of Japan for its magnificent landscape. Mt. Daisen also has been chosen as the third greatest summits in Japan behind Mt. Fuji and Mt. Yari (Yarigatake) at "The Japanese Greatest Summits Ranking" held by NHK, Japan's national public broadcasting organization. The number of climbers in August 2010 was 11,900.

Daisen has been regarded as a god itself since the ancient Jomon and Yayoi eras, and one of the most important mountain for Japanese Shugendo. Climbing the mountain used to be severely prohibited until the Edo period. As a result, Mt. Daisen boasts the largest beech forest in western Japan. There is a Buddist temple Daisenji in the middle of the mountain. Just above the temple is Ogamiyama Jinja (the shrine of the mountain of the great god).
