Musashi-Kosugi Station (武蔵小杉駅,Musashi-Kosugi-eki) is a pair of physically separated interchange passengerrailway stations, a block from each other, located inNakahara Ward of easternKawasaki, Kanagawa, Japan, operated byEast Japan Railway Company (JR East) and theprivate-sector railway operatorTokyu Corporation. Note that the termJR 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.
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 the Shinkansen tracks have no stop. Although it is common to name stations after their operator, the termJR East Musashi-Kosugi Station is therefore non-specific as JR East services both complexes.
Musashi-Kosugi Station is served by JR East'sNambu Line,Yokosuka Line, andShōnan-Shinjuku Line, as well as Tokyu'sTōyoko Line andMeguro Line.

Since December 2023, the new "Tsunashima Road" ticket gate and entrance, located between the Nambu Line and Yokosuka Line platforms, have been open to the public. This entrance provides a faster transfer between the Yokosuka Line platforms and the Tōkyū Railways station, eliminating the need to traverse the Nambu Line platform and helping to reduce congestion.[1]

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 (along the Nambu Line) 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 theYokosuka Line andShōnan-Shinjuku Line connected the station with many directions in Kantō region, includingNarita Airport.
Musashi-Kosugi Station opened as Ground-mae Stop (グラウンド前停留場,Guraundomae-Teiryūjō) and as Musashi-Kosugi Stop (武蔵小杉停留場,Musashi-Kosugi-Teiryūjō) on the Nambu Railway on 1 November 1927. The nearby Kōgyōtoshi Station (工業都市駅,Kōgyōtoshi-eki) on the Toyoko Line opened on 11 December 1939. The Nambu Railway wasnationalized on 1 April 1944, becoming part of into theJapanese Government Railway (JGR) system. Ground-mae Stop became Musashi-Kosugi Station, and the former Musashi-Kosugi Stop was abolished. After the end ofWorld War II, JGR became theJapanese National Railways (JNR). On 16 June 1945, Musashi-Kosugi Station on the Toyoko Line opened, and on 31 March 1953, Kōgyōtoshi Station was abolished.
On 27 November 1988, grade separation work removed the level crossings on Tachikawa-bound tracks, and by 27 December 1988, grade separation work removed the level crossings on Kawasaki-bound tracks. Along withprivatization and division of JNR,JR East started operating the former JNR portion of the station on 1 April 1987. On 6 August 2000, the Tokyu Meguro Line opened; the line was extended to connect to the Tokyu Meguro Line on 22 June 2008. The station was further expanded on 13 March 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.[2]
Platform screen doors on the Nambu Line platforms were installed on 2 February 2022 and began operation on 13 March 2022.[3]
On 18 December 2022, platform 3 on the Yokosuka Line was transitioned to a new side platform.[4] Construction of the platform had been in progress since 2020.[5] Under the updated configuration, the platform number assignments remain as-is.
In the 2015 data available from Japan’s Ministry of Land, Infrastructure, Transport and Tourism, Musashi Kosugi → Nishi-Ōi was one of the train segments among Tokyo's most crowded train lines during rush hour.[6]
In fiscal 2019, the JR station was used by an average of 129,194 passengers daily (boarding passengers only).[7] Passenger usage for the JR East station has almost doubled since fiscal 1999, when the station was the 61st-busiest JR East station with an average of 64,165 passengers daily.[8]
In fiscal 2019, the Tokyu Toyoko Line station was used by an average of 173,414 total passengers daily and the Meguro Line station was used by an average of 49,842 total passengers daily.[9]
The daily passenger figures (boarding passengers only) for each operator in previous years are as shown below.
| Fiscal year | JR East | Tokyu | |
|---|---|---|---|
| 2005 | 70,685 | 92,120 | [10] |
| 2010 | 99,617 | 95,668 | [11] |
| 2015 | 124,325 | 108,191 | [12] |
The area had until the late 2000s been a rather nondescript 'endless' suburbia, broken up only by theTama River. At that time, the locals called the areaMusako. However, with skyscraper construction giving the area an urban feel and outsider influx, the new local nicknameKosugi has emerged.[13] The termMusashi refers toNambu Line, the first train line through the area, which the line name itself is a reference to formerMusashi Province, the southern rim which the line runs along. According to surveys, the district is considered among the more desirable in the Tokyo area, but its popularity waned somewhat after the area suffered flooding due toTyphoon Hagibis in October 2019.[14]
