Musashi-Kosugi Station are a pair of physically separated railway interchange stations, a block from each other, located in Nakahara Ward of eastern Kawasaki, Kanagawa, Japan, operated by East Japan Railway Company and the private-sector railway operator Tokyu Corporation. Note that the term JR East Musashi-Kosugi Station is non-specific, the physical buildings of the Yokosuka and Nambu lines run by the same company are some 400 meters away, connected by a passageway.
Area layout
There are essentially two complexes that make up Musashi-Kosugi Station, with a 400-meter connector passageway between them. The western complex contains a Nambu Line JR East station and a Tokyu station in one building. The eastern station is part of the Tokaido Line and contains JR East Yokosuka Line as well as Shinkansen tracks, though there is no stop. Although it is common to name stations after their operator, the term JR East Musashi-Kosugi Station is therefore non-specific as JR East services both complexes.
JR Musashi-Kosugi Station has two opposed side platforms serving the two tracks of the Nambu Line and one island platform serving the two tracks of the Yokosuka Line. The Shōnan-Shinjuku Line and Narita Express share the Yokosuka Line platforms. The two sections of the JR station are located separately and connected by a 400 m long passage. All platforms are elevated, as is the station building.

History
The area around the station was served by the Nambu and Toyoko lines since the 1920s, but over an extended period of time it was integrated as Musashi-Kosugi Station in 1945. Since then, the station has functioned as a major transfer point for people residing in Kawasaki who commute to Tokyo. Although the station was already a major station along the two lines in the 1990s, the station started further expansion of its role when the Meguro Line opened in 2000 with direct service to the Tokyo subway lines. The 2010 opening of the new platform for the Yokosuka Line and Shōnan-Shinjuku Line connected the station with many directions in Kantō region, including Narita Airport. Musashi-Kosugi Station opened as Ground-mae Stop and as Musashi-Kosugi Stop on the Nambu Railway on November 1, 1927. The nearby Kōgyōtoshi Station on the Toyoko Line opened on December 11, 1939. The Nambu Railway was nationalized on April 1, 1944, becoming part of into the Japanese Government Railway system. Ground-mae Stop became Musashi-Kosugi Station, and the former Musashi-Kosugi Stop was abolished. After the end of World War II, JGR became the Japanese National Railways. On June 16, 1945, Musashi-Kosugi Station on the Toyoko Line opened, and on March 31, 1953 Kōgyōtoshi Station was abolished. On November 27, 1988, Grade separation work removed the level crossings on Tachikawa-bound tracks, and by December 20, 1988, grade separation work removed the level crossings on Kawasaki-bound tracks. Along with privatization and division of JNR, JR East started operating the former JNR portion of the station on April 1, 1987. On August 6, 2000, the Tokyu Meguro Line opened; the line was extended to connect to the Tokyu Meguro Line on June 22, 2008. The station was further expanded on March 13, 2010, when Yokosuka Line and Shōnan-Shinjuku Line trains began stopping. Station numbering was introduced on all Tokyu Railway lines during fiscal 2012, with Musashi-Kosugi Station becoming "TY11" for the Toyoko Line and "MG11" for the Meguro Line.

Surrounding area
The area had until the late 2000s been a rather nondescript 'endless' suburbia, broken up only by the Tama River. At that time, the locals called the area Musako. However, with skyscraper construction giving the area an urban feel and outsider influx, the new local nickname Kosugi has emerged. The term Musashi refers to Nambu Line, the first train line through the area, which the line name itself is a reference to former Musashi Province, the southern rim which the line runs along.
