One of the main experience-based tourism in the Hitoyoshi/Kuma district is going down the Kuma River, which is famous as one of the 3 rapidest rivers in Japan.  There are 2 courses; the ”seiryu (clear stream) course,” going down the river from the dock in Hitoyoshi to the berth in Kuma Village, a total of 8km for 90min; and the ”kyuryu (rapid stream) course,” going down from the berth to just down of the Kyusendo Cave, a total of 10km for 90min (both courses require reservation).  The seiryu course is slow, and is planned to enjoy the lifestyle of waterfowls and fish, as well as wild mountain herbs from each season, operating all year round.  The kyuryu course is thrilling, dynamically going down the 5 major rapids, the boatman’s rowing techniques being the attraction point.  This course only operates for 7 months a year, from April to the end of October.  It is particularly popular on weekends, so please reserve well in advance.
