The N700 series (N700系) is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tōkaidō and Sanyō Shinkansen lines.
N700 series trains have a maximum speed of 300 km/h (186mph), and tilting of up to one degree allows the trains to maintain 270 km/h even on 2,500 m radius curves that previously had a maximum speed of 255 km/h. Another feature of the N700 is that it accelerates quicker than other shinkansen trains, with an acceleration 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).
N700 series trains are presently replacing 300, 500 and 700 series-operated Nozomi runs on a regular basis. By the end of February 2009, the N700 will be responsible for 74 Nozomi services per day.[2]
All Nozomi through runs (over the full route between Tokyo and Hakata) 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.[3]
The N700 is also used on select Hikari services during the day, as well as some early-morning and late-night Kodama runs between Tokyo and Mishima/Hamamatsu.

Variants
16-car Z sets
The prototype 16-car train (Z0) was delivered in March 2005 for extensive testing and endurance running. Cars 1 to 4 were built by Hitachi Ltd., cars 5 to 14 were built by Nippon Sharyo, and cars 15 and 16 were built by Kawasaki Heavy Industries.[4]
The first full-production Z set (Z1) was delivered to JR Central in April 2007, and trains entered revenue service on 1 July 2007, with eight daily Nozomi service runs.
The prototype set Z0 remains as a JR Central test train with cars numbered in the -9000 series, and is not used in revenue service.

16-car N sets (N700-3000 series)
The 16-car N sets are operated by JR West on Tōkaidō and Sanyō Shinkansen services. The first set, N1, was delivered in June 2007, entering service on 1 July 2007.[1]
8-car S sets (N700-7000 series)
The N700-7000 series variant are 8-car sets on order by JR West and JR Kyūshū for use on through-running Sakura services between Shin-Osaka and Kagoshima-Chūō on the Kyūshū Shinkansen from spring 2011.[2] The first set (S1) was delivered to Hakata Depot in October 2008. These trains do not feature the tilting mechanism of the earlier N700 trains.[3]
External livery is Template:Nihongo3 pale blue intended to evoke the colour of traditional porcelain with indigo and gold bodyside lining.[2]
