History

The trains were built by Tokyu Car Corporation in Yokohama between 1993 and 2001, with the first trains entering service in 1993. A total of 70 cars were built.[3]

From 2011, the fleet was gradually repainted into the new corporate livery, and some sets received single-arm pantographs in place of the original lozenge type.[2]

  • Set 9706 in original livery in October 2008

Refurbishment

From 2016, the 9000 series EMU fleet is scheduled to undergo a programme of refurbishment. This involves new interiors, including leather seat covers on the transverse seating bays, interior lighting that can be adjusted to suit day and night conditions, and a new exterior livery of "Yokohama navy blue".[4]
