TheKeikyu Daishi Line (京急大師線,Keikyū Daishi-sen) is a 4.5 km (2.8 mi) railway line^[1] inKanagawa Prefecture, Japan, operated by theprivate railway operatorKeikyu. It connectsKeikyu Kawasaki Station andKojimashinden Station, both located inKawasaki-ku, Kawasaki.

The line was opened on 21 January 1899 by the Daishi Electric Railway (大師電気鉄道) betweenKawasaki Station and Daishi Station, to transport people to theKawasaki Daishi. Electrified at 600 V DC, it is the thirdelectric railway in Japan.^[2][3][4] The Kawasaki Station at the time of opening was located about 800 meters away from the modern Kawasaki Station. It is said that this was due to opposition from therickshaw operators. Later, the initial Kawasaki Station was renamed to Rokugōbashi Station in 1902.^[3][4] The company was renamed Keihin Electric Railway (京浜電気鉄道) on 25 April 1899. The line was double-tracked over its entire length from 29 November the same year, and extended from Rokugōbashi Station to the present-day Kawasaki Station on 1 September 1902.^[2] In 1904, thetrack gauge of the line was changed to 1,372 mm from the 1,435 mmstandard gauge in order to allowthrough service with theTokyo streetcar. This change was reverted in the 1930s to allow through service with the Shōnan Electric Railway (湘南電気鉄道). While the area around the line used to be filled with farmlands and villages, it became an industrial zone by thePacific War.^[4]

After the outbreak of the Pacific War, the line was operated byDai-Tokyu [ja]. Due to increasing demand from the military factories in the region, both the city ofKawasaki and the Dai-Tokyu applied for construction permits to extend the line. It was decided that the two parties each build half of the extension, with Dai-Tokyu extending the line clockwards from Kawasaki Daishi Station and the city extending the line anti-clockwise from Kawasaki Station. Both sections connected atSakuramoto Station [ja], forming a loop-like line. The construction work by Dai-Tokyu was completed on 7 January 1945, and the work by the city was completed on 6 December of the same year. After the dissolution of the Dai-Tokyu,Keikyu took over the line in 1948.^[3] The overhead line voltage was raised from the original 600 V DC to 1,500 V DC on 16 March 1951 except for the Shiohama to Sakuramoto section.^[2] In 1952, Keikyu transferred the section betweenShiohama Station [ja] and Sakuramoto Station to theKawasaki City Tram. The service for the section fromKojimashinden Station to Shiohama was suspended in 1964, and officially abolished in 1970.^[3] Works to remove level crossing betweenHigashimonzen Station and Kojimashinden by moving the line underground was completed in 2019. The same was planned for the section fromSuzukichō Station, but the plan was placed on hold in 2021 due to theCOVID-19 pandemic.^[4]

Keikyu Daishi Line services are operated only by four-carelectric multiple unit (EMU) trains,^[5] stopping at all stations between Keikyu Kawasaki and Kojimashinden. During the weekday off-peak, trains run at 10-minute intervals, increased to 5-minute intervals during the morning and evening peaks.^[6] During the weekends and holidays, trains run at 10-minute intervals, with decreased frequency during the first two hours and the last three hours.^[6]

Services on the line are operated using four-carKeikyu N1000 series formations andKeikyu 600 series formations.^[5][7]
