Overview (history, characteristics, attractions)
The Shimanto River, which flows through the southwestern part of Kochi Prefecture, is one of Japan's cleanest rivers, and is known as "Japan's last clean river" due to the natural scenery and traditional lifestyles that remain prominent in the river basin. Stretching approximately 196 km in length, the river is characterized by its meandering shape as it flows from the mountains to the plains and out to the river mouth.
Historically, it has been an important waterway that has supported the local lifestyle and economy, with people fishing for sweetfish, transporting goods by riverboat, and farming and daily life along the river. In particular, the chinkabashi bridge, which is constructed close to the water's surface, is a unique bridge that is lowered to the river level without any railings to prevent the bridge from being washed away in the event of a flood, and is a symbol of the Shimanto River landscape.
Its attractions include the crystal clear streams, the changing nature of the seasons (fresh greenery, sweetfish season, autumn leaves, starry skies), activities (canoeing, SUP, sightseeing boats, fishing), and the quiet riverside villages and local cuisine (such as grilled sweetfish).
Highlights
- Submerged bridges: Low bridges without railings are scattered around the area, allowing you to enjoy the scenery of them becoming one with the river. This is a popular photo spot.

Things to be aware of (crowds, manners, seasonal precautions, etc.)
- Crowds: On summer weekends and during the Obon period, the riverside and the area around the popular sunken bridges become crowded. Parking and toilets are limited in some areas, so it's best to arrive early.
- Manners: To protect the environment, please be sure to take your trash with you, refrain from making bonfires near rivers, fishing or gathering without permission, and do not trespass on private property. Please follow local rules.
- Safety: Submerged bridges and riverbanks can be slippery when wet, and the current can be rapid when the water level rises. Never approach riverbanks or bridges during rain or when a typhoon is approaching. We recommend wearing a life jacket (when canoeing, etc.).
- Seasonal precautions: Take precautions against UV rays and heatstroke in summer, and against the cold mornings and evenings in spring and autumn. During the rainy season and typhoon season, flooding and road closures are likely to occur, so please check the latest weather and road information.
- Transportation: Public transportation is infrequent in many places, so it is more efficient to consider renting a car or taking a tour.
The Shimanto River is a fascinating place, filled with natural beauty and local culture. When visiting, please be mindful of safety and good manners, and enjoy the river with the awareness of preserving the tranquil environment for future generations.
