Kumagawa River Rafting
Kumamoto · Hitoyoshi
32.2089°N, 130.7597°E
The Kumagawa River, flowing through the mountains of southern Kumamoto, is called 'Japan's three fastest-flowing rivers' alongside the Mogami and Fuji rivers. The 50km stretch from Hitoyoshi to Yatsushiro drops 150m in elevation, creating class II-III rapids. Traditional wooden rafts (operated by boatmen using long poles) run the calmer upper section; inflatable rafts handle the whitewater lower sections.
The river valley's scenery — forested mountains, occasional shrine torii at river bends, stone bridge crossings — represents rural Kyushu at its most pristine.
