Design
The 9000 series trains were built between 1993 and 1999 at Seibu's own Tokorozawa Factory by combining electrical equipment from former 101 series EMUs with new steel bodies based on the New 2000 series design.[2] These were the last trains to be built at the Tokorozawa Factory before it closed in 2000.[2]

As of 1 April 2015[update], the fleet consists of eight 10-car sets, numbered 9101 to 9108, based at Musashigaoka depot for use on Seibu Ikebukuro Line workings.[3]

Interior
History
The first train entered service in 1993, with eight 10-car sets built by 1999.[2] The fleet was refurbished between 2004 and 2008, with new underframe equipment and VVVF inverter control.[2] Refurbished sets are identified by stickers on the cab end doors.[2]
Tamako Line transfer
Beginning in 2020, the 9000 series fleet was shortened to four-car formations and modified to accommodate driver-only operation for use on the Tamako Line. The first of these sets was set 9108, which entered service on the Tamako Line on 1 October 2020.[4] As of 15 June 2021,[update] the entire fleet has been modified for Tamako Line operation,[5] excluding sets 9101, 9106, and 9107, which were scrapped beforehand.[1]
Livery variations
"Red Lucky Train"
From July 2014, set 9103 was repainted in a "Red Lucky Train" livery in collaboration with the private railway operator Keikyu. In return, Keikyu painted one of its own N1000 series sets into an all-over yellow livery similar to the Seibu livery in May 2014.[6] Set 9103 was repainted in an all-over red livery after it was modified for Tamako Line operation.[7]
