The 7000 series was introduced into service on 30 October 1974, when the Yurakucho Line first opened. Its design is derived from that of the 6000 series developed for the Chiyoda Line. They were initially formed as five-car sets, but after the Yurakucho Line was extended to  in 1983, the 7000 series sets were formed as ten-car sets. By 1989, 340 vehicles were built, which were formed into 34 ten-car sets. Refurbishment 
Between 2007 and 2009, the 7000 series fleet was refurbished coinciding with use on Fukutoshin Line services. The sets were fitted with new driver's cabs, CCTV equipment, updated traction and braking systems, automatic train operation, and other miscellaneous technical improvements. Some sets were also shortened to eight cars. The sets were also reliveried with brown, gold, and white stripes coinciding with use on Fukutoshin Line services. They originally sported a yellow bodyside line when used primarily on Yurakucho Line services. Withdrawal 
After the refurbishment programme, a significant portion of the 7000 series fleet was withdrawn; four of these sets were shipped to Indonesia in 2010. In 2020, Tokyo Metro unveiled the 17000 series, which was intended to replace the remaining 7000 series sets by the end of fiscal 2022. As of April 2022, all operations have ended. Overseas operations

Four 7000 series ten-car sets (7117, 7121, 7122, and 7123) were shipped to Indonesia in 2010 for use on suburban services operated by KAI Commuter (previously called "KA Commuter Jabodetabek" or "KRL Jabodetabek") in Jakarta. The four sets were reduced to eight-car formations and are formed as follows, based at Depok Depot. As on 2023, both Set 7022/7122 and 7023/7123 are now bearing the new KAI Commuter gray-white-red color scheme, where set 7017/7117 does not wearing the new color scheme. The two M1 cars in each set are equipped with two pantographs. Note:
 Set 7117 is not fit for operation (Tidak Siap Guna Operasi or TSGO in Indonesian), and currently stored in Depok KRL Depot. Set 7121 is no longer in operation due to damage from colliding with a Pertamina fuel truck. Accidents and incidents

2013 Bintaro train crash: On 9 December 2013, set 7121 (KRL 1131) collided with a Pertamina fuel truck at a level crossing at the Bintaro Permai intersection on the Rangkasbitung Line near Bintaro, South Tangerang, Indonesia, leading to 7 deaths and 45 injuries. The front two carriages of set 7121 as well as the tank truck were both destroyed in the ensuing fire. Set 7121 was retired and scrapped in December 2014. References
