The Tobu 90000 series (東武90000系, Tōbu 90000-kei) is a DC electric multiple unit (EMU) commuter train type on order by the private railway operator Tobu Railway in Japan. Seven ten-car sets are to be built to replace the ageing 9000 series fleet.[3][4]

Design

The end cars feature a reverse slant design inspired by the Takasebune boat, with the front ends curving upwards from the lower part of the cars.[5]

Operations

In addition to operating on the Tobu Tojo Line, the 90000 series sets will also be used for through-running services over the Tokyo Metro Yurakucho Line, Tokyo Metro Fukutoshin Line, Tokyu Toyoko Line and Minatomirai Line.[4]

Formation

Sets are formed as shown below with four motored ("M") cars and six non-powered trailer ("T") cars.[5][2]

History

Details of the new 90000 series trains on order were first announced on 26 March 2025.[4] Tobu states that the 90000 series will consume over 40% less power than the 9000 series.[3]

In November 2025, Tobu announced that the 90000 series would also replace 10000 and 30000 series trainsets, in addition to the 9000 series.[6]

The first 90000 series set, 91001,[7] was delivered from Hitachi's Kasado Works plant in February 2026.[8]

The 90000 series is planned to enter service on 26 September 2026.[2]
