Based on the principle of a "people-friendly dam," the Tugouchi River Dam has been developed to return to nature over a long period of time, and the surrounding green areas have been developed. In addition to supplying the neighboring municipalities with the delicious water of the Tugouchi River, the area surrounding the dam, surrounded by deep greenery, and Lake Tokachi Ryutan, with its clear water flowing from the Hidaka Mountains, are blessed with a beautiful natural environment. The area has great potential as a waterside tourist and leisure zone, and the panorama of water and greenery is a popular spot not only for village residents but also for tourists.
