The 153 series (153系, 153-kei) was an electric multiple unit (EMU) train type operated by Japanese National Railways (JNR) from 1958 until 1983.

[1] The first trains, initially classified 91 series (91系, 91-kei), entered revenue service on 1 November 1958 on Hiei semi express services operating on the Tokaido Main Line between Tokyo and Nagoya.

They were renumbered into the JNR three-digit classification system from 1 June 1959.

[1] From 1972, 153 series sets were introduced on Special Rapid services in the Kyoto-Osaka-Kobe area to compete against private railway operators.
