History
251 series in original livery, 2001
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]
