These sets are used on the Tokyu Oimachi Line.[1] Originally, they were used on Tokyu Den-en-toshi Line and Tokyo Metro Hanzomon Line inter-running services; they were not capable of running through onto the Tobu Skytree Line, and had circular "K" stickers on the centre front cab window to indicate this.[2]
Based on the earlier Tokyu 9000 series EMU design, two sets were introduced in 1992, followed by a third in 1993.[2] The first two sets were delivered with roller blind destination indicators, whereas the third set was delivered from new with 3-colour LED destination indicators.[2] All three sets have since been modified with full-colour LED destination indicators.[2]
The 10-car sets consisted[1] of six motored (M) cars and four unpowered trailer (T) cars, formed as shown below, with car 1 at the Shibuya end.[3][4]

Cars 3, 6, and 9 were each fitted with one lozenge type pantograph.[4] Cars 3 and 9 had wheelchair spaces.[3]

Passenger accommodation consists of longitudinal bench seating throughout.[2]
The first two sets entered service on the Den-en-toshi Line in September 1992, with a third following in 1993.[2]
Set 2103 was the first set to be transferred to the Oimachi Line; it was introduced on the line in 2018 as a 5-car formation.[5] By February 2019, 2000 series sets 2102 and 2103 were in service on the Oimachi Line, with set 2102 being shortened to a 5-car formation as well; they were reclassified "9020 series" and respectively numbered 9022 and 9023.[5]
Set 2101 was transferred to the Oimachi Line in March 2019; like the other sets, it was shortened to 5 cars and was renumbered 9021.[1]
Fifteen surplus cars were scrapped in 2018.[1]
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.[6]
