The E233 series (E233系) is a commuter and suburban EMU type developed by East Japan Railway Company (JR East) from the earlier E231 series design. The first train was introduced in December 2006 for use on the Chūō Main Line, followed by the E233-1000 series variant in 2007 for use on the Keihin-Tōhoku and Negishi lines, and the E233-3000 series outer-suburban variant in December 2007 for use on the Tōkaidō Main Line. A narrow-bodied variant will be introduced on Jōban Line and Tokyo Metro Chiyoda Line inter-running services.[2]

The E233 series, according to the October 2005 press release, features two identical sets of the main equipment in case of failure. This is the first JR East stock to feature such backup measures.
The E233 series provides for better accessibility for the disabled, and is designed to be more comfortable to ride overall than conventional stock. The height between the platform and the train was reduced from the 80 mm of the 201 and 209 series to 30 mm. Seats are 460 mm wide, compared to the 430 mm of the 201 series and 450 mm of the 209 series. For standing passengers the handle straps have been lowered by 50 mm compared to older train models.
This stock also features an air filtration system to remove unpleasant smells. It also features liquid crystal display information screens and automatic announcement system similar to those currently deployed on the E231 series rolling stock on the Yamanote Line.
The stock is the first JR East stock to use full-colour LEDs for the destination indicators on the sides of the carriages. This is due to the fact that the Chūō line has numerous types of services, and colour-coding will help passengers board the correct train.
The first train was introduced in December 2006 for use on the Chūō Main Line, Ōme, and Itsukaichi lines, replacing the aging 201 series trains. The entire fleet of 688 E233 series vehicles (10-car x 42, 6-car x 28, 4-car x 25) was delivered by the end of March 2008.[3] 4+6-car sets are used on the Ōme Line and Itsukaichi Line.
An additional five cars were built at JR East's Niitsu factory in 2009 to replace five cars from 6-car set Ōme 661 withdrawn due to accident damage in 2008.
JR East announced in September 2006 that a fleet of 83 10-car E233 series sets would also be introduced on the Keihin-Tōhoku and Negishi lines from autumn 2007, replacing the 209 series EMUs currently used. The first set was delivered in August 2007. The main difference over the earlier E233-0 series is the absence of passenger door controls.
The first set was scheduled to enter service on 22 December 2007.[4]
This is a new narrow-bodied variant for Jōban Line and Tokyo Metro Chiyoda Line inter-running services, replacing the 203 series and 207-900 series EMUs currently used.[5] The first 10-car set was delivered to Matsudo Depot from Tokyu Car Corporation in May 2009.[6] It was scheduled to enter service from 9 September 2009.[7]
The floor height is lowered to 1,130 mm for improved accessibility, compared to 1,200 mm for the earlier 203 series and 1,180 mm for the 207-900 series and 209-1000 series trains.[8]
The first 10+5-car E233-3000 series outer suburban set (E01 + E51) for use on the Tōkaidō Main Line was delivered to Kōzu Depot in November 2007. This includes two bilevel Green cars.[9] It entered revenue service on 10 March 2008. It is limited to use on the Tōkaidō Main Line between Tokyo and Atami.[10] The second set (10+5-car set E02 + E52) was delivered in February 2010.[11]
JR East announced in September 2009 that 25 10-car E233 series sets would be introduced on the Keiyō Line from summer 2010, replacing the 201 series, 205 series, and 209 series EMUs currently used.[12] The first E233-5000 series set (501) was delivered from JR East's Niitsu factory on 10 March 2010.[13]
