History
Musashi-Kosugi Station is operated jointly by JR East and Tokyu Corporation in Nakahara Ward, Kawasaki. The Nambu Railway's Ground-mae stop opened on 1 November 1927 and was promoted to a full station and renamed Musashi-Kosugi on 1 April 1944 when the railway was nationalised. The Tōyoko side's Kōgyōtoshi Station opened on 11 December 1939; a Tokyu Musashi-Kosugi station followed on 16 June 1945 and absorbed Kōgyōtoshi after the two were consolidated in 1953. JR East took over on 1 April 1987, the Meguro Line opened to the station on 6 August 2000, and on 13 March 2010 a new Yokosuka Line and Shōnan-Shinjuku Line platform was added to the complex.

Notes
The JR Yokosuka Line platform — added in 2010 about 400 metres from the original station — is so distant that a 250-metre connecting passage with moving walkways was needed to link it to the Nambu Line side.
