The Keikyu Daishi Line (京急大師線, Keikyū Daishi-sen) is a 4.5 km (2.8 mi) railway line in Kanagawa Prefecture, Japan, operated by the private railway operator Keikyu.

[3] The company was renamed Keihin Electric Railway (京浜電気鉄道) on 25 April 1899.

[3] The line was extended to Sakuramoto in 1945, and 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, which was transferred to the Kawasaki Streetcar Co. and operated as a tramway.

[3] Originally, the line was built to transport the visitors of Kawasaki Daishi buddhist temple.

But later, factory workers increased, as the east side of the temple became an industrial zone.
