The 253 series (253系) is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company. It was introduced on 19 March 1991 for use exclusively on the Narita Express, a limited express service linking Narita International Airport with stations in the Tokyo area. The 253 series trains were withdrawn from Narita Express services on 30 June 2010, with two trains redeployed on Nikkō and Kinugawa limited express services from June 2011.
