History

edit

The first 225-0 series 8-car train was delivered from Kinki Sharyo on 18 May 2010.[16] The first pair of 225-5000 series 4-car trains was delivered from Kinki Sharyo on 7 September 2010.[13]

Both the 225-0 and 225-5000 series entered revenue service from 1 December 2010.[17]

The unvelling of a new 225-700 series set took place on 18 January 2023. Intended for expansion of the current "A-Seat" paid reserved seating program rolled out on 223-1000 series sets, the new 4-car sets feature an end car which is equipped with Wi-Fi, 2 + 2 abreast seating, a washroom, and two single sliding doors per side (differing from the "A-Seat" cars on the 223-1000 series trainsets which feature three pairs of doors per side). The sets are expected to begin revenue service on the 18 March 2023 timetable revision when the "A-Seat" program is expanded on special rapid services on the Tokaido and San'yo main lines.[18][19] As of 30 January 2023, two sets have been delivered and have since been undergoing testing and driver training.[12]
