Design
The 700 series is characterized by its flat 'duck-bill' nose designed to reduce the piston effect as the trains enter tunnels. 16-car units are painted white with blue stripes beneath the windows, and are used for Nozomi, Hikari, and Kodama services on the Tōkaidō and Sanyō Shinkansen lines, while 8-car units used for the Sanyō Shinkansen Hikari Rail Star services have a darker livery (grey with black window areas and a yellow stripe beneath the windows) which also acts to visually deemphasize the units' nose area, resulting in a more streamlined impression.
As with the 500 series trains, yaw dampers are fitted between vehicles, and all cars feature semi-active suspension to ensure smooth ride characteristics even at high speed. Compared with the small fleet of high-performance, high-cost 500 series trains built for JR West, these trains were designed to give improved ride comfort and interior ambience over the earlier 300 series trains at a lower cost than the 500 series trains. The cost of a 16-car 700 series unit is approximately 4 billion yen compared with around 5 billion yen for a 16-car 500 series train.
