In this episode, a Canadian-born veteran canoeist will take a two-day trip down the Teshio River, which flows through the wilderness of northern Hokkaido Prefecture, with his wife. There are no dams blocking the river from its mouth to around 158km, and the river offers a wide range of rapids and gentle currents, making it a great place to experience the joy of canoeing. The middle reaches of the river are particularly thrilling, with a series of rapids and riffles. A husband, who has been canoeing for 30 years, works closely with his wife to clear many difficult sections while enjoying the river.
