• JR Sanyo Main Line: Uozumi ⇄ Nishi-Akashi

Ōkubo Station opened on 23 December 1888 with the Sanyō Railway's extension between Akashi and Himeji, handling both passenger and freight traffic. Public telegraph service began on 13 December 1902, and on 1 December 1906 the line was nationalised. The line was assigned to the San'yō Main Line by the 12 October 1909 line-name regulations. The station building was rebuilt in 1938, freight handling ended on 1 October 1972, parcel handling on 14 March 1985, and with the privatisation of JNR on 1 April 1987 the station passed to JR West. The 'JR Kōbe Line' nickname was adopted on 13 March 1988. The station was briefly closed by the Great Hanshin earthquake on 17 January 1995 and reopened the next day. The current bridge-style station building entered service on 8 August 1996, expanding the layout from two-platform/three-track to two-platform/four-track and adding elevators, escalators and electronic destination boards. Mycal Akashi opened directly off the south concourse on 23 October 1997. Automatic ticket gates entered service on 31 January 1998, and trains began terminating at Ōkubo from 3 October that year. ICOCA support arrived on 1 November 2003. Station numbering was introduced on 17 March 2018, and limited express "Rakuraku-Harima" began stopping on 15 March 2021.

To distinguish Ōkubo Station from the identically named Ōkubo stations on the Chūō Main Line (Chūō–Sōbu Line local services) and the Ōu Main Line, tickets for journeys to and from this station are printed 「（陽）大久保」, the 陽 prefix marking it as the San'yō Main Line station.
