The first two pre-production sets, 10011 and 10021 were completed in May 2007 and shipped to Yokohama, arriving in June. The first full-production set, 10031, was delivered in July 2007, being hauled via JR tracks from the Kawasaki factory in Hyōgo Prefecture. The full-production sets feature a number of minor design improvements, including green-coloured gradations externally instead of the blue gradations used on the first two sets.
The trains entered service from 30 March 2008 with the opening of the Green Line.[2]
Two second-batch four-car sets were introduced from the start of the revised timetable on 29 March 2014.[4] These sets feature LED headlights, full-colour LED destination indicators, interior LED lighting, and 17inches LCD passenger information displays.[4]
In 2018, it was announced that ten of the 17 sets in operation would be lengthened to six cars each by 2024 as a measure to ease overcrowding on the Green Line.[5] The first lengthened trainset is expected to enter revenue service on 24 September 2022.[6]
From 25 February 2018, set 10161 began operating in a special cream and green vinyl wrapping livery based on the livery carried by former Yokohama city tramcars to mark the tenth anniversary of the opening of the Green Line.[7]
