Shimanto River Source to Sea Bike Tour

The 196 km Shimanto River is one of Japan's last remaining undammed rivers, famous for its clear water, unspoilt surroundings and distinctive chikabashi submersible bridges, built to withstand flooding. 

Enjoy the region’s incredible natural beauty as you journey from the headwaters of the mighty river all the way along the lowly flowing river to the Pacific Ocean. It is a wonderful way to glimpse the lives of people who have long lived in harmony with nature in an environment largely unchanged for centuries.


This adventure starts with a hike into the lush green forest to sample the sweet water that springs from the mountainside at the river's source. After switching to bicycles at the foot of the mountain, we start our journey along the river that changes in character as we get closer to the Pacific Ocean, following a route created to avoid heavy traffic and long tunnels.

Although long, the road is mostly flat or slightly downhill all the way to the sea. Rental bicycles (sports bikes, cross bikes) are prepared, and helpful staff are always on hand in our support car. Canoe tours are also available as an option.

We will design the tour in accordance with the level of and the request by a cyclist. *This tour ends at Nakamura, Shimanto City.
