is the highest point on Rebun Island in Rebun, Hokkaidō, Japan.[1] The mountain consists of marine sedimentary rocks from the Early Cretaceous period, 149–97 million years ago.[2]
The trailhead for the Mount Rebun hike is in Nairo. It is a 3-hour hike with no water available. The trail first passes through fields of sasa-no-ha before entering a forest of pine and birch. The peak rises above the forest to grant an unobstructed view of the entire island.[3]
