History
7000 series set 7134 in original Yurakucho Line livery on the Seibu Ikebukuro Line in March 2008

The sets originally sported a yellow bodyside line when used on Yurakucho Line services, but were gradually reliveried with brown, gold, and white stripes coinciding with use on Fukutoshin Line services. The remaining 7000 series sets will be replaced by the 17000 series.

Overseas operations
A 7000 series set operated in Jakarta, Indonesia

Four 7000 series ten-car sets (7117, 7121, 7122, and 7123) were shipped to Indonesia in 2010 for use on suburban services operated by Kereta Commuter Indonesia (previously called "KA Commuter Jabodetabek" or "KRL Jabodetabek") in Jakarta.[2] The four sets were reduced to eight-car formations and are formed as follows, based at Depok Depot.[2]
