The Taushubetsu River Bridge was built as a railway arch bridge on the former Japanese National Railways Shihoro Line, and even after the closure of the line, it still exists majestically on the surface of the Lake Nukabira. Around the consecutive holidays in May, it is the drought season, so you can see the entire bridge, and if you participate in a tour, you can get close on foot. As reported in the media, there is only a little time left to be seen in full form, is it destined to "spontaneously collapse"?
