Ōguchi Station opened on 20 December 1947 as a Japanese National Railways station on the Yokohama Line, built on land transferred from Nihon University's Fourth Commercial School. Parcel handling ended on 1 February 1984, and the station passed to JR East at the 1987 privatisation. Automated turnstiles entered service on 30 August 1994 and Suica became usable on 18 November 2001. The Beans Annex Ōguchi station-building shop opened on 25 October 2013. The station was assigned number JH14 when station numbering was rolled out on 20 August 2016, smart platform-edge doors entered service on 16 July 2021, and the staffed Midori-no-Madoguchi ticket window closed on 7 October 2021.

One folk etymology for the place name traces it to messengers en route to the Shrine of Morooka Kumano stopping in the area to change into formal ōguchi-bakama trousers before continuing.
