History

The Tsurumi Port Railway (鶴見臨港鉄道, Tsurumi Rinkō Tetsudō) opened the Bentembashi to Hama-Kawasaki line, including the branch to Okawa in 1926, and extended the mainline to Ogimachi in 1928. In 1930, the Tsurumi to Bentembashi section opened, the lines were electrified at 600 V DC, and passenger services commenced on both lines.^{[citation needed]} The Asano to Shin-Shibaura section opened as a freight-only line in 1932, and was extended to Umi-Shibaura in 1940, with passenger services commencing upon the opening of the extension.^{[citation needed]}

The company was nationalised in 1943, and in 1948 the voltage was increased to 1,500 V DC.^{[citation needed]}

On 20 August 2016, station numbering was introduced with Tsurumi line stations being assigned station numbers between JI01 and JI10.^[5][6] Station numbers were also introduced to the Umi-Shibaura branch (station numbers JI51 and JI52) as well as the Ōkawa branch (station number JI61).
