Site description Sarobestugenya marsh is in the Sarobetsugawa river basin. At the beginning of pioneer days, the area had 20,000 ha, and 70% was peatlands. There are many marshes such as Penkenuma marsh, Pankenuma marsh and Kabutonuma, making stop over spots for migrating waterbirds. Sarobestugenya marsh consists of low moors and high moors, so you can study the history of moors by just taking a walk on the boards. During spring migration season, some summer visitors such as Siberian Rubythroat, Stonechat and Yellow Wagtail can be observed in the area. During autumn migration season, 7,000-8,000 Bean Geese stopover, making this a common sight in autumn. Recent breeding of Japanese Cranes suggests that the area still has good habitat for wildlife.
