History
Nishi-Nippori Station opened on 20 December 1969 as part of the Teito Rapid Transit Authority's Chiyoda Line. Only the northern half of the platform — closer to Kita-Senju — was usable at the start because Japanese National Railways had not yet finished rebuilding the bridge over its main line above, and trains ran in three-car formations. The full station opened on 20 March 1971 with the Chiyoda Line's extension between Ōtemachi and Kasumigaseki, and a month later, on 20 April, JNR opened its own Nishi-Nippori Station as an interchange — the second-most-recent Yamanote Line station after Takanawa Gateway. The JNR station passed to JR East at privatisation on 1 April 1987 and accepted Suica from 18 November 2001. The Eidan subway was privatised into Tokyo Metro on 1 April 2004, and the Toden-run Nippori-Toneri Liner station was added on 30 March 2008.

Notes
From 1934 to 1943 the present-day Nishi-Nippori 5-chōme block was served by Keisei Electric Tramway's Dōkanyama-dōri Station, but after that line was closed there was no rail station in the immediate area for 26 years until the Chiyoda Line opened.
