M/S of two men balancing on many logs tied together as they travel along a fast moving river. Another shot of men balancing on logs - possibly workers in the Japanese lumber industry. The long raft like constructions travel through treacherous waters. C/U of rows being moved on a rowing boat. Camera tilts up to show the men rowing. Various shots of them negotiating choppy waters. High angle shot of the boat passing through some rapids. Two women holding parasols are on board. Another boat passes the camera - perhaps these are pleasure boats? Shot from on board one of the boats as it moves through rocky river. High angle shot of boats in calmer waters.
