Although it's not one of Japan's highest mountains, at 1729m Daisen (大山) looks impressive because it rises straight from sea level – its summit is only about 10km from the coast. Daisen is part of the Daisen-Oki National Park (大山隠岐国立公園).
The popular climb up the volcano is a five- to six-hour return trip from Buddhist temple Daisen-ji. From the summit, there are fine views over the coast and, in perfect conditions, all the way to the Oki Islands.
The mountain catches the northwest monsoon winds in the winter, bringing lots of snow to what is western Japan's top skiing area. Among the slopes are Daisen White Resort and Daisen Masumizu-kōgen Ski Resort.
