The Shiribetsu River (尻別川) wends almost 130km from the Bifue Pass just west of Lake Shikotsu, around Yotei-zan and on to the Japan Sea. Choose your section, and it can be a playground for both hardcore paddlers and families alike. This section at the lower end of the river is arguably one of the most laid back sections of the river. At the start of this section is a hydro power station outlet, but this relatively exciting start is the sum total of the rapids you’ll see, beyond some swifts further down. From this section downstream, paddlers can paddle all the way to ocean, 25km away. This 5km section, however, is a pleasant ~2hr paddle.
