Route map

The Yokohama Line (横浜線 Yokohama-sen) is a Japanese railway line of the East Japan Railway Company (JR East) connecting Higashi-Kanagawa Station in Yokohama, Kanagawa and Hachiōji Station in Hachiōji, Tokyo. The line forms part of what JR East refers to as the "Tokyo Mega Loop" (東京メガループ) around Tokyo, consisting of the Keiyo Line, Musashino Line, Nambu Line, and Yokohama Line.[1] The line's name comes from the section between Nagatsuta and Higashi-Kanagawa that runs through the city of Yokohama. Nicknamed the Hama-sen (浜線) by locals,[2] the line serves commuters in the southwestern suburbs of Tokyo and northeastern suburbs of Yokohama.

The line was opened by the private Yokohama Railway (横浜鉄道 Yokohama Tetsudō) on 23 September 1908 and leased to the government in 1910.[7] The line was nationalized on 1 October 1917.[7]

The Higashi-Kanagawa - Haramachida (now Machida) section was electrified on 1 October 1932, with the Haramachida - Hachiōji section electrified on 14 April 1941.[7]

The Higashi-Kanagawa - Kozukue section was double-tracked by 1968, extended to Aihara by 1980, and completed to Hachiōji on 6 March 1988.[7]
