The Shimanto River is famous for being free of dams and for its bridges, called chinkabashi, that have no side railings. The bridges were designed thus to prevent damage by flooding, and the word chinkabashi means “submersible bridge.” The longest of these, Sada Chinkabashi, spans nearly a thousand feet. With its gentle flow, the Shimanto River is also perfect for easy kayaking, and camping facilities make it easy maximize your enjoyment of the outdoors.
