The E531 series (E531系) is an electric multiple unit used by East Japan Railway Company (JR East) in Japan. It was introduced by JR East on 9 July 2005 to replace the aging 403 and 415 series EMUs running on the Jōban Line from Ueno station in Tokyo. The stock is a dual-voltage (1,500 V DC & 20 kV AC) development of the DC-only E231 series suburban EMU design, and can run at speeds of up to 130 km/h in service.
Trains are formed in 10-car (set numbers K-401 onward) and 5-car (set numbers K-451 onward) sets. 15-car formations are generally run between Ueno and Tsuchiura. 10- and 5-car sets operate singly north of Tsuchiura, and 5-car sets are used on the Mito Line.
Pairs of double-deck Green cars were added to the 10-car sets from 6 January 2007, and all 10-car sets included Green cars by the start of the revised timetable on 18 March 2007.
