Operations
The 03 series trains operated on the Tokyo Metro Hibiya Line, with through-running to and from the Tobu Skytree Line and before 2013, on the Tokyu Toyoko Line.
Formations
As of 1 April 2017[update], the fleet consisted of 40 eight-car sets, formed as shown below, with car 1 at the Naka-Meguro (south) end.[3] Sets consisted of four motored ("M") cars and four non-powered trailer ("T") cars.[3]
| Car No. | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
|---|---|---|---|---|---|---|---|---|
| Designation | CT1 | M1 | M2 | Tc | Tc' | M1 | M2 | CT2 |
| Numbering | 03-100 | 03-200 | 03-300 | 03-400 | 03-500 | 03-600 | 03-700 | 03-800 |
- The M1 cars (cars 2 and 6) each had two lozenge-style pantographs.[3]
- Cars 1, 2, 7, and 8 in sets 09 to 28 had five pairs of doors per side instead of three.[3]

Withdrawal
The 03 series trains began to be replaced by new 13000 series trains from 25 March 2017.[4] The first set to be withdrawn, set 14, was removed for scrapping in February 2017.[5]
The 03 series was fully retired from the Hibiya Line on 28 February 2020 with no fanfare; Tokyo Metro cited the inconvenience created from the crowding of train enthusiasts during the farewell event for the 6000 series as the main reason for this decision.[6]
Resale
Kumamoto Electric Railway
Three former 03 series EMUs were resold for use by the Kumamoto Electric Railway in Kumamoto Prefecture between 2018 and 2020.[7] They entered service on 4 April 2019.

Nagano Electric Railway
On 31 January 2020, Nagano Electric Railway announced the second-hand purchase of a few 03 series units, which would be redesignated as the 3000 series. They're intended to replace the older 3500 series (ex-TRTA 3000 series, themselves too ex-Hibiya Line stock) which currently form the backbone of local service rolling stock on the railway.[8]
