Oku Station opened on 20 June 1929 in what is now Shōwachō, Kita, Tokyo. By line classification it sits on the Tōhoku Main Line's Nippori–Oku–Akabane branch, the so-called Oku Spur; operationally it is served by Utsunomiya and Takasaki line trains. Parcel handling ended on 1 October 1964 and the station passed to JR East at the JNR privatisation on 1 April 1987. Suica IC cards were accepted from 18 November 2001, the staffed reserved-seat office (Midori-no-Madoguchi) closed on 21 August 2007, and the remote station-operation system (now the "Customer Support Call System") was introduced on 8 March 2015. The 13 March 2021 timetable revision merged the former commuter-rapid services on the two lines into the Rapid Rabbit and Rapid Urban categories, leaving Oku with no rapid stops at all.

The station's name is pronounced "Oku", but the same characters in the neighbouring Arakawa Ward place names Higashi-Ogu and Nishi-Ogu are read with a voiced second syllable, leaving the station and the district it stands beside spelt the same but pronounced differently.
