The Mogami River Basin is located in the northeastern part of Japan, primarily in Yamagata Prefecture. It is known for its rich natural resources and diverse ecosystems, supporting various plant and animal species. The basin is also significant for agriculture, particularly rice farming, due to its fertile soil and abundant water supply. The Mogami River, which flows through the basin, is approximately 225 kilometers long and is one of the major rivers in Japan. It originates from the Chūgoku Mountains and eventually empties into the Sea of Japan. The river and its surrounding areas are popular for recreational activities, including fishing and hiking.
