The 251 series (251系) is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) on Tōkaidō Line Super View Odoriko limited express services in Japan since April 1990.[1]

The four sets, numbered RE1 to RE4 and based at Tamachi Depot in Tokyo, are formed as follows, with car 1 at the Izukyū-Shimoda end, and car 10 at the Tokyo and Shinjuku end.[2]

Built by Kawasaki Heavy Industries and Kinki Sharyo,[3] the first two sets were introduced from 28 April 1990.[4] These were followed by two more sets in 1992.[1]

The 251 series was awarded the 1991 Laurel Prize, presented annually by the Japan Railfan Club.[5] A formal presentation ceremony was held at Shinagawa Station in Tokyo on 1 March 1992.[6]

The fleet underwent a programme of refurbishment between December 2002 and March 2004, which included the addition of new seating, and repainting the sets into a new colour scheme.[2]
