The Agano River (阿賀野川,Agano-gawa) is a river system in theHokuriku region ofHonshu,Japan. It is also called theAga River or theŌkawa River inFukushima.^[1] It is designated as aClass A river.^[1]

The source of the river isMount Arakai on the border of Fukushima andTochigi prefectures. It flows to the north and meets the Nippashi River fromLake Inawashiro and theTadami River in theAizu Basin, and then turns to the west and empties into theSea of Japan. The Agano River flows for 210 kilometers. It has a watershed area of 7,710 square kilometers.^[2] Approximately 560,000 people live in the basin area.^[1]

In 1964–1965, a chemical factory atKanose village inNiigata Prefecture releasedmethylmercury into the river and causedNiigata Minamata disease.^[3]

Agano is connected to the adjacentShinano River by the 10,8-km long Koagano channel.^[4]

There are several hydroelectric power plants on the Agano River:

Inawashiro Power Plant (107.5 MW), constructed in several stages in 1899–1940. It was the site of Japan's first high-voltage, long-range power transmission line.
Numazawanuma Power Plant (43.7 MW), constructed in 1952.^[5] It was the firstpumped-storage power plant in Japan.
