4K Japan Drive [Kei Truck] Shimanto River Bridge Tour 

The Shimanto River is also known as "Japan's last clear river."
We toured the bridges, focusing mainly on the subsidence bridges.
We started at Sada subsidence Bridge (Imanari Bridge) and drove to Hanya subsidence Bridge.
*Subsidence bridge: a bridge that submerges underwater when the water level rises. It has no railings to prevent driftwood from getting caught.
It's a beautiful sight that seems to symbolize the nature-rich Kochi.
