Oku Station opened on 1 September 1962 with the Japanese National Railways Akō Line extension from Imbe to Higashi-Okayama, in what is now Setouchi City, Okayama Prefecture. Daily operations were contracted out from 1 October 1969, parcel handling ended on 1 February 1984, and the station passed to JR West at JNR privatisation on 1 April 1987. A staffed Midori-no-Madoguchi reservation counter opened on 1 November 1992 and operated until 28 February 2022, with full unstaffing from the following day. ICOCA service has been available since 1 September 2007. The station consists of a single side platform serving a bi-directional track, with step-free access from the ticket gate via a slope.

The station stands in what is now Setouchi City, but until the municipal merger of 2004 its address read Oku-gun, Oku-chō — district, town and station all written with the same kanji, 邑久.
