The 113 series (113系, 113-kei) is a Japanese suburban electric multiple unit (EMU) train type introduced in 1963 by Japanese National Railways (JNR), currently operated by West Japan Railway Company (JR-West) and Shikoku Railway Company (JR Shikoku), and formerly also operated by East Japan Railway Company (JR East) and Central Japan Railway Company (JR Central).
The design was derived from the earlier 111 series, and used newer MT54 motors with an output of 120 kW (160 hp). They are used in the mild temperature areas of Japan, due to their brakes not being capable of handling cold weather. The 115 series were built to operate in colder areas.
