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,[4] which were cascaded to surface lines to replace older 5000 and 5200 series sets.
From 26 March 2016, the 4000 series began operation on the JR East Joban Line.[5]
