Lonely Planet review
This meandering river is marked by cascading waterfalls, carved-out gorges and gurgling rapids. Casual hikers can follow its path for a 14km stretch connecting Nenokuchi, a small tourist outpost on the eastern shore of the lake, to Yakeyama, from where relatively frequent buses return to either Nenokuchi (¥660, 30 minutes) or the main tourist hub of Yasumiya (¥1100, one hour). The entire hike should only take you about three hours. Set out in the early morning or late afternoon to avoid slow-moving coach parties.
