Ōji Station opened on 28 July 1883 with the inauguration of Nippon Railway's Ueno–Kumagaya line, and is one of the oldest surviving stations on what is now the Tōhoku Main Line. The line was nationalised under the Railway Nationalisation Act of 1906 and formally assigned to the Tōhoku Main Line in the line-name reorganisation of 1909. The Ōji Electric Railway, ancestor of today's Toden Arakawa Line tramway, opened a connecting stop in 1915, and from 1928 the station was served by Keihin Line commuter trains while long-distance services ran past without stopping. The station building was rebuilt in 1961, JNR's privatisation in 1987 transferred the station to JR East, the Eidan Namboku Line opened on 29 November 1991 turning Ōji into a three-line interchange, and the Namboku Line passed to Tokyo Metro at the operator's privatisation in 2004.

In March 2009 it emerged that wastewater pipes from a south-exit toilet block installed in 1966 had been mistakenly connected to a rainwater drain, sending sewage into the nearby Shakujii River for more than forty years.
