Operations
editThese 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]
Design
editBased 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]

Oimachi Line transfer and reclassification

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]
