History
Ōkuma Station serves the town of Watari in Miyagi Prefecture on the Jōban Line and is sited 338.4 rail kilometres from the line's nominal starting point at Nippori in Tokyo. The site was originally established by Japanese National Railways on 1 October 1960 as Ōkuma Signal Station, a passing-place built to support a realignment of the route. It passed to JR East at privatisation on 1 April 1987 and was promoted from signal station to passenger station on 2 August 1988. ICカード Suica became usable here on 26 October 2003.

Notes
The station owes its existence to a route realignment: the former main line continued straight where the current down line now curves away, and the original right-of-way is still visible alongside the present tracks.
