The 16-car N sets were operated by JR-West on Tokaido and Sanyo Shinkansen services.
The first set, N1, was delivered in June 2007, entering service on 1 July 2007.
16 sets were in service by April 2014.

The fleet of 16 "N" sets subsequently underwent modifications at Hakata Depot between fiscal 2013 and fiscal 2015 to add improved braking systems and other features incorporated in the later N700A series sets.
Modified sets were re-designated "K" sets, with cars renumbered in the -5000 subseries.
