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 9701, which wasn't part of the Yokohama Navy Blue refurbishment programme, was scrapped on 11 December 2020.^[4]

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.^[5]
