The first 8000 series trains were introduced on 1 April 1981, initially operating as 6- and 8-car sets. By 1982, all sets were lengthened to 8-car formations. Between 1987 and 1994, the fleet was lengthened again to 10-car formations.Due to a surge in ridership on the Tozai Line, the Teito Rapid Transit Authority procured three 10-car 8000 series sets and introduced them into service in 1987. TRTA also considered building more 5000 series trains, but its base design was over two decades old, and development of a new train type was still underway. These 8000 series sets were transferred to Hanzomon Line services within a year.
From 2004, a programme of refurbishment commenced, with some sets receiving VVVF control and three-phase motors. In February 2016, set 8114 received full-colour LED destination indicators.
