This high-altitude marsh is located on a lava plateau on the eastern side of Mt. Shokanbetsu, in the western part of Uryu Town under the jurisdiction of the Sorachi Regional Subprefectural Bureau in central-west Hokkaido. It is the source of the Oshirari River, a tributary of the Ishikari River, and at an altitude of 850 meters, there are over a hundred large and small ponds and marshes stretching 2 kilometers east to west and 1 kilometer north to south, and when the snow melts in spring, it becomes a continuous large marsh. Sphagnum moss, sedges, and other marsh plants grow luxuriantly on the peat layer and bloom in July. It is designated as part of the Shokanbetsu-Teuri-Yagishiri Quasi-National Park, and there is a road up to halfway, but it is about a 2-hour walk beyond that. The Uryu Marsh was registered as a Ramsar Convention wetland in 2005. [Ichiro Kashimura] [Reference] |This high moor spreads across the eastern slope of Mt. Shokanbetsu.
