SPOT
An environmentally protected area within a national park, a scenic spot for viewing autumn foliage, where the dam and nature intertwine
Located in Minami-ku, Sapporo, this 102.5m high concrete arch dam was completed in 1972 for the purposes of flood control of the Toyohira River and hydroelectric power generation. The dam lake is named Lake Jozanko and can hold about 30 Sapporo Domes worth of water. Located within Shikotsu-Toya National Park, the approximately 2km distance from the dam entrance to the dam is closed to general vehicles, motorbikes and bicycles all year round for environmental protection reasons; visitors must walk or use an electric bus to get to the dam.
The area around the dam is a scenic spot surrounded by steep rock slopes, and together with the dam's spectacular tourist discharge (held every year from June 1st to October 31st from 9am to 4pm), it forms a magnificent landscape. It is an especially popular spot for viewing autumn leaves in Sapporo.
