The first trains entered service from 17 October 1988. In March 1998,
Automatic Train Control was introduced on the 02 series, which was supplemented with a
Train Automatic Stopping Controller (TASC) system allowing them to stop automatically at stations since November 2002.
Hōnanchō branch sets In 1996, six 3-car 02 series sets were introduced for use on the Hōnanchō branch line. These sets feature an altered livery with a black stripe atop the waistline band. Internally, LED passenger information displays are used, and the longitudinal seats use piped side partitions. After
Hōnanchō Station was upgraded in 2019 to accommodate 6-car trains, two of these sets were scrapped in 2021. In July 2022, Tokyo Metro announced that 3-car trains would be withdrawn from the Hōnanchō branch line from 27 August of that year.
Refurbishment The 02 series fleet went under major refurbishment, with the first treated trains returning to service from February 2010. Refurbishment included the use of new Toshiba PMSM (
permanent magnet synchronous motors), as fitted to the new
Chiyoda Line 16000 series trains, offering energy savings of approximately 10%. Internally, pairs of 17-inch LCD passenger information monitors were installed above the passenger doors. The interior was finished in a pale salmon pink colour reminiscent of the original 300 series trains used on the line, and externally, a white "sine wave" design was added to the red bodyside stripes, again reminiscent of the 300 series livery.

Withdrawal A fleet of 53 new six-car trains was introduced in fiscal 2018 to replace the 02 series trains by fiscal 2023. The new trains are classified as
Tokyo Metro 2000 series. The last 02 series set was withdrawn in December 2024.
Overseas use Two 02 series cars were transferred to
FEATI University in the Philippines for training use. ==References==
