The Keihin-Tōhoku Line—Negishi Line (京浜東北線・根岸線 Keihin Tōhoku-sen—Negishi-sen ?) is an 81 km railway line in Japan that connects the cities of Saitama, Warabi, Kawaguchi, Tokyo, Kawasaki, and Yokohama. The origins of its name are Tokyo( 東) - Yokohama (横) and Tohoku Main Line (東北本線). Although it is a contiguous service, it is officially divided into 2 segments as follows:

  • Keihin-Tōhoku Line (京浜東北線 Keihin Tōhoku-sen ?) is the segment between Omiya and Yokohama stations. It runs along portions of the Tōhoku Main Line, and Tōkaidō Main Line. The name literally means "Tokyo-Yokohama and Tōhoku Line."
  • Negishi Line (根岸線 Negishi-sen ?) is the segment between Yokohama and Ōfuna stations.

However, because the service is contiguous, the entire service (including the "Negishi Line" portion) is often simply called the Keihin-Tōhoku Line for convenience. The Keihin-Tōhoku Line—Negishi Line trains are recognizable by their light blue stripe (the line's color on maps is also light blue).



The Keihin Line opened in 1914 as an electrified passenger line connecting Tokyo Station to Takashimacho Station in Yokohama. (The latter station was renamed Yokohama Station in 1915, when the former Yokohama Station was renamed Sakuragicho Station). The Keihin Line service was extended north through the Tohoku Main Line to Akabane Station in 1928 and to Ōmiya Station in 1932: this service was initially called the Tōhoku-Keihin Line in announcements.

The Keihin Line initially had third-class and second-class cars, analogous to today's ordinary cars and Green Cars respectively. Second-class service ended in 1938 in order to accommodate special military cars during World War II. The military seating was converted to seating for women and children after the war, and back to ordinary seating in 1973 amid overcrowding concerns: second-class service was briefly restored in the 1950s but abandoned shortly thereafter.

In 1956, the Keihin-Tohoku Line was physically separated from the Yamanote Line between Tamachi and Tabata, allowing more frequent service. Through service with the Negishi Line began in 1964. The frequency increased again in 1968 when the Tohoku Main Line moved to separate tracks. Rapid service trains were introduced in 1988 to further ease congestion in the Yamanote Line corridor.


Rush hour at Ueno station, Yamanote line and Keihin-Tōhoku line

Trains run every 2–3 minutes at peak hours, every 5 minutes during the daytime, and less frequently the rest of the time. In most instances, these trains are classified as futsū (local), stopping at all stations en-route. However, during the daytime, trains are classified as kaisoku (rapid). These rapid trains skip some stations in central Tokyo, where it runs parallel to the Yamanote Line.

Presently, 209 series EMUs run on all Keihin-Tōhoku Line services. From autumn 2007, these will be gradually replaced by new E233 series 10-car EMUs.
