The prototype 11-car train will enter passenger service in the autumn and JR East plans to introduce production trains from 2018 onwards.
The 1.5kV dc trains will be formed of five unpowered and six powered vehicles, which will be equipped with VVVF traction inverters. The E235s will also be the first trains in the JR East fleet to be fitted with oil-free compressors.
The E235 features internal and external styling by industrial designer Mr Ken Okuyama, who has previously designed cars for Porsche, Ferrari, and Maserati.
During passenger trials the train will operate without any hanging advertising to gauge passenger reaction to alternative forms of onboard advertising, including digital signage.
The Yamanote Line is one of the busiest commuter lines in Tokyo, carrying around 3.8 million passengers a day.
