The Teshio River, which flows through northern Hokkaido, is the fourth-longest river in Japan (and the second-longest in Hokkaido) with a mainstream length of 256 kilometers. The river is very suitable for canoeing because no obstacles are crossing the river from its mouth to 158 kilometers. A canoe touring competition called “Down The Teshi-o-pet” is held down the river from its upper reaches to its mouth. The annual event is held in July and attracts about 150 participants from Japan and overseas. (Unfortunately, the 2020 event has been canceled.)
The rich natural environment of the Teshio River attracts many fly fishing enthusiasts. You can target rainbow trout and white-spotted char over 40 centimeters in length, and if you are lucky, you may even encounter Japanese huchen, known as phantom fish. Fishing tours by skilled guides are also popular.
In winter, you can also enjoy outdoor activities unique to the northern part of Japan, such as cycling on the snow and fishing for smelt.
