Located in Shimanto City, Kochi Prefecture, Yasuna Waterwheel Village is a beautiful destination that perfectly captures the essence of traditional Japanese rural life. The area is defined by the harmonious blend of the Shimanto River's natural beauty and a historic irrigation system. Historically, numerous waterwheels were used to irrigate the surrounding fields, creating a rhythmic, soothing sound known as "kattan-kotton" that has become a signature of this peaceful landscape.
While many functional agricultural waterwheels have decreased over time, the beautifully maintained waterwheels seen today serve to preserve the region's history and culture. Watching the wheels slowly turn amidst the lush greenery and hearing the gentle flow of water offers a profound sense of tranquility. It is an ideal destination for travelers looking to escape the bustle of the city and reconnect with the natural cycle of life.
The history of Yasuna Waterwheel Village is deeply rooted in the "Yonkamura-mizo" irrigation system, which supported local agriculture for generations. A weir was constructed along the Goka branch of the Shimanto River to distribute water across the four villages of Akita, Yasuna, Saoka, and Kotsuka.
These waterwheels were more than just tools; they were vital infrastructure that sustained the community, and their rhythmic sounds became a natural part of the daily soundtrack of life. Although modern farming has changed the landscape, the local community continues to maintain these waterwheels to honor and preserve the cultural heritage and the iconic scenery of the region.

The main attraction is the sight of the waterwheels lining the waterways. Walking along the paths while listening to the gentle splashing of water is a uniquely meditative experience. The area also features the well-maintained Yasuna Waterwheel Village Park, making it a relaxing spot for families and groups.
Seasonal changes add even more magic to the area. In early summer, the vibrant hydrangeas blooming along the waterways create a stunning contrast against the wooden textures of the waterwheels. This colorful scenery is a favorite for photographers seeking to capture the essence of a Japanese summer.
