About This Destination

Called the 'last clear stream of Japan', the Shimanto River flows undammed for 196 kilometers through lush Kochi countryside, ideal for canoeing and cycling.

The Shimanto River earned its reputation as Japan's last unspoiled river thanks to its remarkably clear waters flowing freely without a single dam along its main course. The river is famous for its chinkabashi (submersible bridges), low bridges built without railings that are designed to submerge during floods rather than resist them, creating popular photo opportunities. Canoeing and kayaking are the most popular ways to experience the river, with half-day and full-day tours available for all skill levels from spring through autumn. Cycling along the riverside roads is equally rewarding, with gentle routes and rental bicycles available at Nakamura Station. The area is also known for freshwater delicacies including ayu sweetfish, river shrimp, and freshwater eel grilled over charcoal.

Frequently Asked Questions

How do I get to the Shimanto River?

Take the JR Dosan and Yodo Lines toward Nakamura Station (Tosa-Kuroshio Railway) in western Kochi. From there, rental cars, bicycles or sightseeing boats explore the river.

What are the chinkabashi (submersible bridges)?

They are low, railing-less bridges designed to slip under floodwaters. Nearly 50 cross the Shimanto, and driving or cycling over them above the clear green water is the river's signature experience.

What activities can I do on the Shimanto?

Enjoy houseboat (yakatabune) cruises, canoeing and SUP, cycling the riverside road, and tasting local specialities like sweetfish (ayu) and aonori seaweed.
