The Shimanto is celebrated as ‘the last clear stream in Japan’, a broad, beautiful river that flows for nearly two hundred kilometres through the mountains and countryside of western Kochi without a single large dam on its main course. Its clear green waters, wooded banks and old-fashioned rural scenery make it one of Shikoku’s loveliest landscapes. The river’s signature sight is its chinkabashi — low ‘sinking bridges’ built without railings so that floodwaters pass harmlessly over them, crossing the water in long, simple lines. Visitors explore the Shimanto by canoe or kayak, by cycling the riverside paths, or on a traditional boat cruise, making it a wonderful place to slow down and enjoy unspoiled river country.

Tips
Come from late spring to autumn for the warm weather that suits canoeing and cycling, and book a canoe tour or rent bikes to explore the river actively rather than just viewing it. See at least one chinkabashi sinking bridge up close, take care crossing them as they have no railings, and allow a relaxed pace to enjoy the unspoiled scenery.
