226 vehicles were ordered, at a cost of approximately 30 billion yen. The trains incorporate increased front-end crash protection with the inclusion of crushable zones.
The total order of 226 vehicles consists of 110 225-0 series vehicles with a maximum speed of 130 km/h for use on Tokaido Main Line and Sanyo Main Line Special Rapid services and 116 225-5000 series vehicles with a maximum speed of 120 km/h for use on the Hanwa Line. Livery for each is identical to that of the 223 series vehicles on each of these routes.
