Shimanto River

Background

The Shimanto River lies in western Kochi Prefecture, flowing from the Shikoku mountains to Tosa Bay; it is 196 kilometres long, with a basin area of 2,270 square kilometres. The river is broad and calm, with terraced fields, forests and small villages on both banks, preserving the old riverside scenery of Japan; fishing and river-nori production in the basin are still part of local livelihoods. Because it lies far from large cities and has no dams, its water has stayed clear, and together with the Nagara River in Gifu Prefecture and the Kakita River in Shizuoka Prefecture it is counted among Japan's three free-flowing rivers.

Local customs

• Ride a river boat or paddle a canoe downstream, watching the terraced fields and forests on both banks
• stroll and take photos on the submersible bridges, but do not go onto them when the water is high
• cycle or walk along the river, linking the small villages on its banks.

Travel tips

• River boats and canoes are mostly run locally, so check the officially published information before you travel
• in the rainy season the river rises quickly, so check the weather and water level before setting out
• supply points along the river are few, so bring drinking water and food. You can take the train to the Nakamura area of Shimanto City and then continue by bus or rental car along the river, or drive from Kochi City
• check the officially published routes.
• Spring and summer bring the lushest green, ideal for boating and cycling
• in autumn, red leaves spread along the river
• in winter the riverside is quiet, with few visitors.
