Wada basin

A Wada Basin is an artificial pond or reservoir that was created in Japan hundreds of years ago. People built them to help irrigate crops and provide drinking water for livestock. The Wada Basins are built into the ground and have a mud wall around the edge to keep out water. The water in the Wada Basins comes from rivers and streams, and the basins are usually filled with fish and frogs. People use the water for drinking and watering their gardens, and also for fishing. The Wada Basin is an important part of life in Japan, and still serves as a source of water and food today.
