About

The Otafunbe Chashi site in Urahoro, Hokkaidō, Japan, is a historically significant archaeological location, once occupied by the Ainu people. This site features a fortified chashi, a type of Ainu defensive structure, characterized by a mound and a surrounding ditch. The mound rises to approximately 27 meters and is topped by a flat area measuring about 21 by 7 meters. The site is steeped in local legends, such as the story of a conflict between the Akkeshi and Shiranuka Ainu, which highlights its cultural significance. The chashi's strategic position at the edge of the Shiranuka Hills illustrates its defensive purpose. Designated as a national Historic Site, Otafunbe Chashi offers valuable insights into the defensive strategies and cultural practices of the Ainu during the Late Iron Age and into the Early Post-Classical Period.
