Yotsuya Station opened on 9 October 1894 as a Kōbu Railway stop on what is now the Chūō Main Line, between Shinjuku and Ushigome. The Kōbu Railway was nationalised on 1 October 1906, the Yotsuya section was double-tracked in 1895 and quadruple-tracked in 1929, and Marunouchi Line platforms opened on 15 March 1959 — a post-war redesign let the line run on an elevated structure over the JR cut. Namboku Line platforms followed on 26 March 1996, with Yotsuya as the line's southern terminus until Tameike-Sannō opened on 30 September 1997. Both subway lines passed to Tokyo Metro at the April 2004 privatisation, and a 12-car Chūō Rapid platform extension was completed by 12 October 2024.

On 23 June 2010, JR East appointed a female station master at Yotsuya at the same time as one at Mejiro — the first female station master at a station in Tokyo across both the JNR and JR eras.
