The Osaka Metro 400 series ( Japanese: 大阪メトロ400系, Hepburn: Ōsaka Metoro 400-kei) is an electric multiple unit (EMU) train type built by Hitachi Rail for Osaka Metro. Entering service on 25 June 2023, a total of 23 six-car sets are to be built.
A total of 23 six-car sets are due to be introduced ahead of the 2025 World Expo, [4] and to replace the 20 and 24 series trainsets currently in use on the Chuo Line. [5] The 400 series is the first new Osaka Metro rolling stock type to be ordered following the privatization of the Osaka Municipal Transportation Bureau. [6]
The design of the 400 series was overseen by Ken Okuyama. [3]
The exterior design of the 400 series is intended to resemble that of a spaceship, [5] featuring an octagonal front end and headlight clusters at each of the four corners. [3] The 400 series was developed in consideration of the 2025 World Expo, high levels of comfort and safety, accessibility, and to be "fun to ride". [7] In addition, the train type has a lower floor height than its predecessors, as well as more clearly marked priority seating. [8] The sets use aluminium for body construction. [3]
The interior incorporates calm color palette, and the longitudinal seats use a varied color palette. [8]
Passenger accommodation consists of longitudinal seating throughout, except for one car, which features transverse seating. [5] Priority seating is provided. [8] Passenger information displays are provided, displaying information in Japanese, English, Chinese, and Korean. [5]
The 400 series was originally designed with a full-glass door between the passenger cabin and the crew compartment, but due to structural issues, sets used a half-glass door instead. [2]: 3
The luggage racks are 10 millimetres (0.39 in) lower than those of other train types. [3]
The sets are formed as follows. [3]
Numbering | 409-01 | 402-01 | 403-01 | 408-01 | 401-01 | 406-01 |

The trains were first formally announced by Osaka Metro on 9 December 2021. [5] Production of the 400 series fleet commenced [1] in 2022, [9] and the first set was delivered from Hitachi's Kasado plant in October of that year. [1] On 7 December 2022, Osaka Metro unveiled the first 400 series to the press. [3]
It was originally intended that the 400 series would enter service in April 2023; [10] however, its introduction into service was delayed until 25 June 2023. [6] Of the 23 sets to be produced, 12 sets are expected to enter service in fiscal 2023. [11]
On 23 May 2024, the 400 series received the Laurel Prize, presented annually by the Japan Railfan Club. [12]
