The 117 series (117系, 117-kei) is a Japanese suburban electric multiple unit (EMU) train type introduced in 1979 by Japanese National Railways (JNR), and currently operated by West Japan Railway Company (JR-West). The train type was operated by Central Japan Railway Company (JR Central) from 1987 until 2013. A total of 216 cars were manufactured. When JNR was privatized and divided into the individual JR Group companies, JR Central received 72 cars, while JR-West took possession of 144.
