History

The first two sets entered service on the Den-en-toshi Line in September 1992, with a third following in 1993.

Refurbishment, Oimachi Line transfer, and reclassification to 9020 series

In March 2018, set 2103 (excluding its T2 and T1 cars) underwent a programme of refurbishment. The refurbishment included the implementation of a new traction system as well as an updated interior with new seating moquette and additional wheelchair spaces. In addition, the original lozenge pantographs were replaced with single-arm pantographs. Later that year, the 2000 series fleet was withdrawn from Den-en-toshi Line services and shortened to 5-car sets for use on the Oimachi Line beginning with set 2103. By February 2019, 2000 series set 2102 had also been transferred; both sets were reclassified "9020 series" and respectively numbered 9022 and 9023. Set 2101 was transferred to the Oimachi Line in March 2019; it was subsequently renumbered 9021. The fifteen cars deemed surplus as a result of the fleet's transfer were scrapped in 2018.

Future replacement

In May 2024, Tokyu Railway announced that as part of its 2024 capital investment plan, the 9020 series, together with the 9000 series, is scheduled to be replaced with a new fleet of rolling stock based on the 6020 series.
