Mukawa River Paddling (Fukuyama to Tomiuchi, Hokkaido, Japan)

The Mukawa River 鵡川 is one of Hokkaido's premiere whitewater rivers, with a 40km+ middle section consisting of regular CIII rapids, very remote access, and numerous boulder gardens. This section from Fukuyama 福山 to Tomiuchi 富内 is the lower-most section of the rowdy part of the Mukawa, but does not let up in terms of descent. Expect house-sized boulders, a very real feeling of remoteness, and frequent long rapids. Supremely packraftable, and a great challenge for experienced open-deck canoeists.
