The E257 series (E257系) is a DC electric multiple unit (EMU) train type operated in Japan by East Japan Railway Company (JR East) and built jointly by Hitachi, Kinki Sharyo, and Tokyu Car Corporation.

Variants

Two variants exist: the original E257-0 series for use on Chuo Main Line Azusa and Kaiji limited-express services, and the E257-500 series for use on Uchibo Line, Sotobo Line, Sobu Main Line, Narita Line, and Kashima Line limited-express services.[1]

E257-0 series

This sub-series version was introduced on 1 December 2001, to replace the aging 183 and 189 series rolling stock on Chuo Main Line Azusa and Kaiji services. Based at Matsumoto depot, the fleet consists of sixteen 9-car sets (M101 to M116) with a full cab at the Matsumoto end and a gangwayed cab at the Tokyo end, and five 2-car "add-on" sets (M201 to M205) with a full cab at the Tokyo end and a shunting cab only at the Matsumoto end.

The type was the recipient of the 45th Blue Ribbon Award (2002) of the Japan Railfan Club.
