This is Japan's best whitewater rafting experience in the spring with over 12 kms of world-class grade of 3 to 4 rapids. This half-day rafting tour in Minakami is a continuous roller coaster of whitewater bliss with rapid after rapid of amazing actions and very scenic sections including the well-known 3 canyon sections of Momiji Canyon, Minakami Canyon and Suwa Canyon. The summer tour is more of a mellow experience with less challenging rapids but still plenty of fun both in and out of the boat.
