First introduced on 10 February 2002, a total of 336 cars were built with orders divided between Nippon Sharyo, Tokyu Car Corporation, and Kawasaki Heavy Industries.

The 3000 series entered service on 10 February 2002.

10-car set introduction
In 2010, Odakyu announced plans to procure eight cars to extend six-car sets to 10-car sets. These cars were delivered between 2010 and 2011 from Kawasaki Heavy Industries' Hyogo plant and used to augment six-car sets 3280 and 3281 to 10 cars; the sets were renumbered 3091 and 3092, respectively. The first 10-car set, 3091, entered service on 20 January 2011.

five additional 10-car sets have since been introduced: 3081, 3082 (formerly eight-car sets 3665 and 3664, respectively), and 3093–3095 (formerly six-car sets 3282, 3278, and 3279, respectively ).

Refurbishment
Beginning in fiscal 2022, the 3000 series has undergone a programme of refurbishment, which includes additional wheelchair spaces, surveillance cameras, and energy-saving control equipment.

Doraemon-liveried "F-Train"
In August 2011, 10-car set 3093 was reliveried in a Doraemon livery to commemorate the opening of the Fujiko F. Fujio Museum in Kawasaki, Kanagawa. The train was scheduled to run in its livery for one year, but this was cut short due to complaints from the Tokyo Metropolitan Government that it violated metropolitan ordinances regulating advertising on train exteriors. The decorated "F-Train" remained in service until 30 September 2011, before the exterior advertising was removed.
