Set 7713 at Wakabadai Station, 1988

The 7000 series began service in 1984. The 7000 series was built for local train service, and the first sets were five-car sets, rather than 4, 6 or 10 cars. The running performance of the new series was nearly the same as the Keio 6000 series.[10] By 1996, 190 cars of the 7000 series had been built.

From 2001, 7000 series sets were introduced on Special Express, Semi Special Express, Express, and Rapid trains.[11]

Keio announced in 2010 that 18 more of its 7000 series cars would be converted to VVVF inverter control.[12] As of 2023, all the train sets have been converted to VVVF inverter control in 2012.[13]
