Mount Daisen (大山 Daisen?), is a volcanic mountain in Tottori Prefecture, Japan. It has an elevation of 1,729 metres. This mountain is the highest in the Chūgoku region, and the most important volcano on the Daisen volcanic belt: a part of Southwest Honshu volcanic arc, where the Philippine Sea Plate is subducting under the Amurian Plate.
Mount Daisen is a complex volcano, made by repeated volcanic activity over thousands of years. Eruptions in this area started 1.8 million years ago and resulted in Old Daisen some 500,000 years ago. The Mount Daisen of today, New Daisen, resulted from a second group of eruptions which started 50,000 years ago and ended 10,000 years ago in the caldera of Old Daisen. 50,000 years ago, this mountain had a plinian eruption from which volcanic ash can be found as far away as the Tohoku Region of Japan. Daisen is one of the 100 famous mountains in Japan, and also one of the Chūgoku 100 mountains.
Mount Daisen, which stands directly on the Sea of Japan, was regarded as one of the most important mountains for Japanese Shugendō. According to the Izumo Kokudo Fudoki, completed in 733, it was called Ōkami-take, literally, Mountain of the great god.
Mount Daisen has been called Hōki Fuji and Izumo Fuji, depending on which side of the mountain the viewer is standing on. These names are based on the old Hōki and Izumo provinces.
