A total of 97 vehicles are on order.

These entered service from the start of the revised timetable on 17 March 2012.[4][5]

Design

The trains are based on the earlier 683 series Thunderbird design with increased front-end crash protection and the inclusion of crushable zones for the first time on JR-West limited express rolling stock.[6] Livery is similar to that used on 683 series Thunderbird sets, with a maroon stripe below the dark grey window band for the Kitakinki and Kōnotori trains,[7] and "ocean green" for the Kuroshio trains.[4][5]
