since 1 April 2015[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters"., the fleet consists of 23 six-car sets (numbered 01 to 23), all based at Oji depot in Tokyo.[1]
Prototype
A prototype four-car set was built by Kawasaki Heavy Industries in 1990 (formed of cars 9101-9201-9301-9801) for testing on the Chiyoda Line prior to the opening of the Namboku Line in 1991.
1st batch
Full-production four-car sets 02 to 07 were delivered in 1991 ahead of the Namboku Line opening, followed by an additional set in 1992, set 08, to act as a spare.
The original four-car sets were reformed as six-car sets coinciding with the opening of the extension of the line from Yotsuya to Komagome on 26 March 1996. This was achieved by renumbering the centre cars (9200 and 9300) of sets 02, 04, 06, and 08 as 9600 and 9700 cars which were inserted into sets 01, 03, 05, and 07. New-build (2nd batch) intermediate cars (9200-9300-9600-9700) were then inserted into sets 02, 04, 06, and 08. The resulting minor differences led to odd-numbered sets 01 to 07 being classified as "A sets", and even-numbered sets 02 to 08 becoming "B sets".Script error: No such module "Unsubst".
2nd batch
Four new six-car sets (09 to 13), plus the four sets of four additional intermediate cars described above were built by Kawasaki Heavy Industries between 1995 and 1996, coinciding with the opening of the extension of the line from Yotsuya to Komagome in March 1996. Floor height was reduced by Template:Cvt compared with the 1st-batch sets from Template:Cvt. Seat width was increased from Script error: No such module "convert"..Script error: No such module "Unsubst".
3rd batch
Two new six-car sets (14 and 15) were built by Tokyu Car Corporation to coincide with the opening of the extension of the line from Template:STN to Template:STN on 20 September 1997. Externally and internally, these were identical to the 2nd-batch trains.Script error: No such module "Unsubst".
4th batch
Six new six-car sets (16 to 21) were built by Nippon Sharyo between 1999 and 2000 ahead of the opening of the extension of the line from Tameike-Sannō to Meguro on 26 September 2000. The motored cars 3 (9300) and 4 (9600) in these sets have only one powered bogie, as opposed to two on earlier sets.[2] Friction stir welding was used in the construction of these sets to produce a more attractive exterior finish.Script error: No such module "Unsubst".
5th batch
Two new six-car sets (22 and 23) entered service from 22 May 2009.[3] These include a number of design improvements over earlier sets, including a redesigned front end, single-arm pantographs, and improved air-conditioning. The number of motored cars is reduced from four to three per 6-car set, with car 3 (trailer car) numbered in the 9400 series. Car 4 (9600) has both bogies powered.[2] Seat width is increased by Template:Cvt to Template:Cvt, and floor height is reduced by Template:Cvt to Template:Cvt.[4]

Sets 01 to 21
The 1st to 4th batch sets (01-21) are formed identically as follows, with four motored ("M") cars and two non-powered trailer ("T") cars, and car 1 at the northern end.[1] Motored cars 3 and 4 in sets 16 to 21 each have only one motored bogie.[1]

- Cars 2 and 5 have wheelchair spaces.[1]
- Car 4 is designated as a "mildly air-conditioned" car.[1]
Sets 22 and 23
The two fifth-batch sets are formed as follows, with three motored ("M") cars and three non-powered trailer ("T") cars, and car 1 at the northern end.[1]
| Car No. | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Designation | CT1 | M1' | T | M1 | M2 | CT2 |

Refurbishment
The early sets (01 to 08) are scheduled to undergo a programme of refurbishment from 2016, with the first treated sets returning to service from August 2016.[5] Internally, the transverse seating bays at the ends of cars will be replaced by longitudinal bench seats, and wheelchair spaces will be added to one end of each car.[5] Externally, the refurbished sets will receive a revised livery with wavy turquoise and white stripes at waist height and shoulder height to make the line colour more visible at stations with platform edge doors.[5] The refurbishment programme of the older sets was completed in 2018 with set 08 completing refurbishment on 20 November of that year.[6]
Lengthening
In 2021, Tokyo Metro announced that it would lengthen 9000 series sets from 6 cars to 8 cars per set from 2022 as a means to mitigate congestion on the Namboku Line.[7]Template:Rp
In October 2021, two intermediate cars, numbered 9409 and 9509, were delivered from Kawasaki Heavy Industries' Hyogo plant.[8]
In May 2023, set 9109 was sent to the depot at Shin-Kiba where it was reformed into an eight-car set. On 13 December 2023, Tokyo Metro announced that set 9109 would enter service on 16 December, and that 13 sets (sets 09–21) will be lengthened to 8-car sets using newly built cars.[9] All additional cars will be built by Kawasaki, and are based on the newer Tokyo Metro 16000 series. The original cars are also being refurbished similarly to previously refurbished sets, with new signage, security features, and a more compact auxiliary power supply. A wheelchair accessible "free space" has also been added to every car. Tokyo Metro Rolling Stock Department Design Division Assistant Manager Tomoya Wantanabe said that the newly renovated sets would be used for 20–25 years.
