The E131 series (E131系) is a DC electric multiple unit (EMU) train type operated by the East Japan Railway Company (JR East). It began operations in the Chiba area on 13 March 2021, on the Sagami Line on 18 November 2021, and on the Nikkō Line and the Utsunomiya Line on 12 March 2022. The trains are equipped for driver-only operation (wanman (ワンマン, “one man”)).

The E131 series trains have stainless steel bodies.[1] They have LCD passenger information displays above the doors,[1] as well as wheelchair-accessible and stroller-accessible “free spaces” on all cars. As they are equipped for “wanman” driver-only operation, body-mounted cameras are utilized to monitor passengers boarding and alighting the train; these cameras are then fed to displays located in the driver’s cab.[1][2] They also feature semi-automatic doors, allowing passengers to operate the doors during driver-only operation.[1][2]

Internally, the trains are equipped with security cameras and emergency call switches.[1]

Some trains in each subseries are numbered -X80, as they have a slightly different equipment configuration due to the presence of track monitoring equipment.
