The 485 series (485系, 485-kei) (and the earlier 481 and 483 series variants) is a Japanese limited express electric multiple unit (EMU) type introduced in 1964 by Japanese National Railways (JNR), and subsequently operated by the East Japan Railway Company (JR East), West Japan Railway Company (JR-West), and Kyushu Railway Company (JR Kyushu). Approximately 1,500 vehicles were built, although by April 2016, JR East is the only operator still using this type.
