The N700 Series Shinkansen is a high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tōkaidō and Sanyō Shinkansen lines. The prototype 16-car train was delivered in spring 2005 for extensive testing, and trains entered into service on July 1, 2007, with eight daily Nozomi service runs.

Full-production N700 trains have a maximum speed of 300 km/h, and tilting of up to one degree will allow the trains to maintain 270 km/h even on 2,500 m radius curves that currently have a maximum speed of 255 km/h. Another feature of the N700 is that it accelerates quicker than other shinkansen trains, with an acceration rate of 2.6 km/h/s. This enables it to reach 270 km/h in only three minutes. Because of these improvements, trains can travel between Tokyo and Osaka on a Nozomi run in as little as 2 hours and 25 minutes (5 minutes faster than before).

From March 2008, the N700 began service on two Hikari services, between Shin-Yokohama and Hiroshima stations, and between Tokyo and Nagoya stations. N700 trains are also used on some early-morning and late-night Kodama train runs between Kokura and Hakata. In all, there are presently a total of 46 daily train services utilizing the N700: 41 Nozomi runs, 2 Hikari runs and 3 Kodama runs.

Currently, there is at least one N700 Nozomi departure per hour in each direction over the full route between Tokyo and Hakata. All of these Nozomi through runs are scheduled to use the N700 exclusively by 2009. By 2011, all regularly-scheduled Nozomi services, including runs limited only to the Tokaido Shinkansen, will be operated by the N700.^[1]
