Overview: Our stage this time is the Kushiro River in eastern Hokkaido Prefecture. A couple of canoeists will spend 3 days descending the 154-kilometer-long river. The uppermost part of the river flows through a deep forest decorated with autumn foliage. The 2 skillfully maneuver their canoe through the river, which has thick branches and fallen trees lying in the water. It is an exciting canoe trip where the canoeists show their experience and skills. Later, we also show you some footage of the Japanese Huchen, Japan's largest freshwater fish, that lives in the Kushiro River.
