The first train was delivered in May 2007, and the trains entered service in September 2007 on inter-running services between Odakyu and the Tokyo Metro Chiyoda Line, displacing 1000 series sets, which were cascaded to surface lines to replace older 5000 and 5200 series sets.
The trains are based on the JR East E233 series EMU design, but with narrow bodies to permit subway running. The traction motors are fully enclosed, as on the 50000 series VSE sets, to reduce environmental noise.
As of 1 April 2012, 14 10-car sets were in service, formed as follows.
The 4000, 4200, and 4400 cars each have one single-arm pantograph.
