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] By 2012, the entire fleet was retrofitted with VVVF inverter control.^[13]
