The 3000 series was introduced on 3 February 2005 on the newly opened Nanakuma Line between Tenjin-Minami and Hashimoto. Unlike the 1000 series and 2000 series trains operated on the Kūkō Line and Hakozaki Line, the 3000 series trains are standard gauge (1,435 mm) and use linear motor propulsion.
The exterior was designed by the German industrial designer Alexander Neumeister. Each side of the cars is equipped with three pairs of doors. The bodyside is white with a small light-green line which runs from the front along the top of the windows. This represents the ridge of Mount Abura (located in Jōnan-ku, Sawara-ku and Minami-ku, Fukuoka). Muromi River (located in Nishi-ku and Sawara-ku, Fukuoka) is represented by a light blue stripe along the bottom of the train. The trains are 25% shorter than the 1000 and 2000 series. There is an emergency door at each end of the train.
Trainsets consist of four cars, all motored. The trains are equipped with ATO and can be operated unmanned, but driver-only operation is used. The trains use Insulated-gate bipolar transistor (IGBT), a variable-frequency drive system, and LED train destination indicator panels. All cars are air-conditioned.
