John writes, 

Kochi prefecture is the perfect place to peddle your way into Japan’s natural beauty.

In mid March my cycling companion and I completed a three day 200km+ (120mile+) cycling tour of the Shimanto River area of Kochi Prefecture, The area is great for the intermediate or advanced cyclist. We rode along Kochi’s beautiful coastline, up into the mountains and along the Shimanto River. The river is beautiful with clear and inviting water.

There are good river access points and two nice seaside parks, including Ukitsu Beach that would be ideal for a long lunch and a swim in the sea.
