Site location and context
Lake Koetoi-Onuma is located in the east of Wakkanai City, has a perimeter of 12 km around, and a maximum depth of 2.2 m. In 1958, the lake was connected with the sea by a flood prevention project that straightened the Koetoigawa river. There is abundant wildlife in the fresh water lake and the brackish water. Many birds breed here, and Tundra Swans and ducks stop over in spring and autumn migrating seasons.
