Located south of central Shimonita, Mt. Ontake (574 m) has long been a familiar symbol of the town. It is also one of the mountains where visitors can experience the distinctive geological feature known as a “rootless mountain” (klippe).
Mt. Ontake is associated with Ontake mountain worship and the tradition of shugendo, a form of Japanese mountain asceticism. Along the trail, you will find stone monuments dedicated to doji (attendant deities), Fudo Myoo, and small stone shrines.
Along parts of the ridge, green schist is exposed at the surface, as it is at nearby Aoiwa, and continues as far as the area around the office of Ontake Shrine. From there toward the summit, the mountain is composed of conglomerate and sandstone of the Atokura Formation.
Mt. Ontake is close to central Shimonita, making it easy to combine a hike with a meal in town and a stroll through streets that retain the atmosphere of the Showa era.
On maps published by Shimonita Geopark, Mt. Ontake is written as 御嶽.
