AT A GLANCE
Why go?
The Atsubetsu River (厚別川) is a 41-kilometre waterway flowing through Sapporo, Hokkaido — the second-longest river in the city and the largest tributary of the Toyohira River. Its name comes from the Ainu language, where "Ashiripet" means "new river," a reference to its history as a wild watercourse that changed its course with every annual flood. Today, after decades of flood-control engineering, the river's banks have been transformed into a series of parks, green spaces, cycling paths, and one of Japan's most celebrated waterfalls.↗↗↗
From its source near Sorachi Peak in Minami Ward to its confluence with the Toyohira River in neighbouring Ebetsu, the Atsubetsu River threads through forested hills, farmland, and residential neighbourhoods, offering walkers, families, and nature lovers a surprisingly varied green corridor just minutes from Sapporo's urban core.↗↗
A River Born from Floods
For most of its recorded history, the Atsubetsu River was known locally as a "wild river" (暴れ川). Its sinuous course through volcanic ash terraces meant it shifted position every spring melt, and settlers in the 1870s found themselves wading through freezing water each winter because no bridges spanned the river — some reportedly lost toes to frostbite making the crossing. Mail carriers in the 1890s tied envelopes to stones and threw them across to the opposite bank.
