History
The first 3000 series set, 3001, entered service in 1999, initially as an eight-car formation used on the Tokyu Toyoko Line. This was subsequently reformed as a six-car set following delivery of the rest of the fleet destined for the Meguro Line. A total of 13 six-car sets (78 vehicles) were built by 2001.

On 26 March 2019, Tokyu Corporation announced that the entire Meguro Line fleet, including the 3000 series fleet, would be lengthened from six cars to eight cars from the first half of fiscal 2022. Six of the additional cars were completed in late March 2022 and transported to Nagatsuta depot. As of February 2023, all sets have been lengthened to eight cars.
