奥羽山脈
The Fukushima Basin is created by the surrounding Ōu Mountains in the west and the Abukuma Highlands in the east, with the Abukuma River flowing through the center of the basin, from south to north. Multiple tributaries to the Abukuma River source in the Ōu Mountains before flowing down into Fukushima, namely the Surikami, Matsukawa, and Arakawa rivers. These rivers flow eastward through the western side of the city until joining up with the Abukuma River in the central parts of the city. The irrigation from these rivers were formerly used for the cultivation of mullberry trees; however, in the latter half of the 20th century cultivation was switched from focusing on mullberry trees, and instead growing a variety of fruit orchards.
