History
Ōtsuka Station opened on 1 April 1903 on Nippon Railway's Yamanote shortcut linking Ikebukuro to Tabata, with both passenger and freight operations. It came into state ownership through the 1 November 1906 Railway Nationalisation Act and into the JR East network at the 1 April 1987 privatisation of Japanese National Railways. Freight handling was withdrawn on 1 October 1974 and parcel service on 1 November 1986. Automatic ticket gates entered service in October–December 1990, Suica acceptance began on 18 November 2001, and a north-south concourse opened on 17 October 2009. The wooden south-side station building was demolished in 2009; platform doors were activated on 20 April 2013, the on-site Atré Vie Ōtsuka complex opened on 12 September 2013, and the JR East ticket counter (Midori no Madoguchi) closed on 31 October 2021.

Notes
The station was originally planned as Miyanaka Stop, after the small place-name of its construction site in then-Sugamo village, before being renamed Ōtsuka after the larger neighbourhood near the central exit; the surrounding town later took the station's name in the 1969 jūkyo-hyōji address reform.
