Agagawa

The main stream of the Agano River system is called the Agagawa River in Fukushima Prefecture. It enters Niigata Prefecture and becomes the Agano River, and of the 210 km long river that flows into the Sea of ​​Japan, 123 km of it is the Agagawa River. Approximately 80% of the Agano River's drainage area is in Fukushima Prefecture. It is the only river draining the Aizu region within the prefecture, but part of the basin straddles Koriyama City and Iwase County. It has an important river system network that connects various parts of Aizu, including the Okawa River (main Agagawa River), the Nippashi River, and the Tadami River.
