TheNegishi Line (Japanese:根岸線,romanized: Negishi-sen) is a Japanese railway line which connectsYokohama andŌfuna stations. It is operated byEast Japan Railway Company (JR East). Freight trains also operate on this line, and it is essential for the southernKeihin region.
The Negishi Line does not exist as an independent service. All trains operate athrough service onto theKeihin-Tōhoku Line past Yokohama toKamata,Tokyo,Minami-Urawa andŌmiya. As a result, the entire service between Ōmiya and Ōfuna is typically referred to as theKeihin-Tōhoku—Negishi Line (Japanese:京浜東北線・根岸線) on system maps and in-train station guides. Keihin-Tōhoku Line—Negishi Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).
SomeYokohama Line trains to/fromHachiōji orHashimoto travel onto the Negishi line and terminate/originate atSakuragicho, with a small number of AM & PM Peak services continuing to/fromIsogo orOfuna.
All trains on the Negishi Line are local trains, stopping at all stations. Between approximately 09:30 & 14:30 trains displayRapid, as they omit some stops in Central Tokyo on theKeihin-Tohoku Line portion of the service.
During the daytime, trains operate every 10 minutes between Yokohama and Ofuna, and every 5-10 minutes between Yokohama and Isogo.
TheHamakaiji limited express service also formerly operated on the Negishi Line until the service ceased operating on January 3, 2019.[1]
Freight trains are a common sight on the Negishi Line. The following rail companies either link up to or use the Negishi Line for the purpose of transporting freight.

The oldest station on the line isSakuragichō, which was opened by theJapanese Government Railways on June 12, 1872[note 1] as the first railway terminal in Yokohama of the first railway line in Japan. The line was extended toKōzu on July 11, 1887; trains had to reverse direction at Yokohama via aswitchback to continue their journey. This was alleviated by a bypass line betweenKanagawa andHodogaya which opened on August 1, 1898. The branch was named the Tōkaidō Main Line Branch Line on October 12, 1909.
Takashimachō Station opened between Kanagawa and Yokohama on December 20, 1914 as the terminus of an electrified Keihin Line (the predecessor of today's Keihin-Tōhoku Line). On August 15, 1915, a newYokohama Station opened, absorbing nearby Takashimachō and becoming the new terminus of the line. The old Yokohama station was renamedSakuragichō and the Sakuragichō – Hodogaya bypass closed. Keihin Line service was extended to Sakuragichō on December 30, 1915 when freight service ceased on the branch.
The line was planned to be extended to Ōfuna, and in 1920 the Government Railways decided that the extension route would be parallel to the Ōoka River and then turn to Hodogaya. From Hodogaya to Ōfuna, additional tracks would be added to the existing Tōkaidō Main Line. However, this plan was scrapped after theGreat Kantō earthquake of 1923.[2] Later, the planned extension was revived with a completely different route: "The railway from Sakuragichō in Kanagawa Prefecture toKita-Kamakura" was added to the list of railways to be built in the Railway Construction Act on March 31, 1937.[3] This provision was the basis for the construction of the present-day Negishi Line.
Yokohama Station moved on October 15, 1928; between then and January 26, 1930, temporary platforms for the Keihin Line were provided on either side of the station.
On May 19, 1964, the line was extended toIsogo. The line was renamed the Negishi Line after one of the new stations. The Takashima freight line opened on June 1 that year and freight service returned to the line after a nearly 50-year absence.103 series trains were introduced to the line in October 1965.
The line was extended from Isogo toYōkōdai on March 17, 1970. The final section between Yōkōdai andŌfuna opened on April 9, 1973; On October 1 that year, freight service commenced between Ōfuna and Isogo.
Freight services between Ōfuna and Isogo ceased on February 1, 1984; three days prior to this, the line adoptedAutomatic Train Control. On April 1, 1987 theJapanese National Railways were privatized, with ownership of the Negishi Line passing to JR East; JR Freight took over freight services on the line.
Some trains began operating through onto theYokosuka Line on March 15, 2008.[citation needed]
TheSakuragichō train fire occurred on April 24, 1951.
On May 20, 1970 a 103 series train derailed betweenShin-Sugita and Yōkōdai, injuring two people.[citation needed]
