History
Ogikubo Station opened on 21 December 1891 as a petition stop on the privately built Kōbu Railway, the line that became today's Chūō Main Line. Nationalisation in 1906 placed it on the Chūō East Line, and in 1909 the rail-naming reform attached it to what is now the Chūō Main Line. The Nakano–Ogikubo–Kichijōji section was double-tracked in 1909 and electrified in 1919. The Eidan subway's Ogikubo Line — quadruple-tracked between Nakano and Ogikubo to relieve the Chūō Line — opened to passengers here on 23 January 1962, with Tōzai Line through-services from Nakano following on 28 April 1966; the Ogikubo Line was rebranded as the Marunouchi Line in 1972. The combined Ogikubo Line / Marunouchi Line passed to Tokyo Metro on 1 April 2004. Suica was accepted on the JR side from 18 November 2001 and PASMO on the Metro side from 18 March 2007. Twelve-car operation on the Chūō Line rapid service began on 13 October 2024 after platform extensions completed the previous day.
