The 255 series (255系), or Bōsō View Express (房総ビューエクスプレス), is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan. It was introduced into commercial service on 2 July 1993, and was specifically designed to serve on Limited express services from Tokyo to the Bōsō Peninsula.

Design
The trains were built jointly by Kinki Sharyo and Tokyu Car, with a steel body design based directly on the earlier 253 series EMUs built for Narita Express services, although the window height was increased by 100 mm. It is the first JR East limited express rolling stock to feature VVVF Insulated Gate Bipolar Transistor traction control system, based on the results of trials with the prototype 209 series commuter EMUs.
DT56E bogies are used on motored cars, and TR241E bogies are used on trailer cars.

The destination indicators on the sides of cars were changed from the original roller blind type to LED indicators between October and November 2005.
