, also is a mountain in the Daikō Mountain Range on the border between the prefectures of Mie and Nara, Japan. Its top is the highest point in Mie at 1695m (5,561feet). Walking trails from the Nara side start from a car park at about 1,400 metres. The mountain is famous for wild deer, and also for wild birds, especially wrens and Japanese robins, as well as treecreepers and woodpeckers. In 1980, an area of 36,000 hectares in the region of Mount Ōdaigahara and Mount Ōmine was designated a UNESCO Man and the Biosphere Reserve.[1]
The mountain was also selected by the Tokyo Nichi Nichi Shimbun and Osaka Mainichi Shimbun newspapers[2] as one of the 100 Landscapes of Japan in 1927. It was referenced on American indie folk band Fleet Foxes's 2017 song "Third of May / Ōdaigahara".
