Ashiribetsu Falls, Cascading waterfall in Takino Suzuran Hillside National Government Park, Japan

Ashiribetsu Falls drops about 26 meters vertically, showing a continuous flow of water cascading against dark rocks within a densely forested national park. The water flows over multiple levels surrounded by steep rock walls on both sides.

The waterfall formed after a large eruption of the Shikotsu caldera tens of thousands of years ago buried the upper Abetsu River in pumice and scoria. Erosion resumed and cut a gorge through the weakly welded scoria, leaving the strongly welded part as a cliff of columnar joints whose height became the 26 m fall. In 1880 the Kaitakushi built a watermill workshop upstream, renamed the Abetsu sawmill, which closed in 1886.

The name Ashiribetsu comes from the Ainu word ashiribetsu, meaning "new river"; the same word is the origin of the place name Atsubetsu. The falls are one of Japan's Top 100 Waterfalls, a list compiled from selections across the country.

The falls are reached from the Takino Suzuran Hillside Park's stream mouth car park by the A Course, a walking path along the stream of about one kilometre. Hokkaido Route 341 passes over the top of the falls. The waterfall lies in Sapporo's Minami ward, on the upper Ashibetsu River.

During winter, the falls maintain partial liquid flow while ice formations create natural sculptures, offering a different visual appearance from other seasons. These contrasts between water and ice make each visit a distinct experience.
