History

In June 2016, JR Central announced plans to build a new prototype 16-car trainset, the N700S (with "S" standing for "Supreme"), to evaluate new technologies and features on the Tokaido and Sanyo Shinkansen lines starting in March 2018.[3]

Developed from the earlier N700A series (itself a refinement of the N700 series), the N700S incorporates several new features. Refinements to the ATC and braking systems enable emergency braking distances to be reduced by 5%, improving safety during events such as earthquakes.[3] The traction system uses silicon carbide components, and combined with a new aerodynamic design, reduces power consumption by approximately 7%.[4] Toshiba SCiB LTO batteries allow the train to operate at low speed during power disruptions, enabling it to move to a safe location for passenger evacuation and maintain essential functions such as toilets.[5]

An optimized underfloor equipment layout makes it possible to use the same standard design for 16-car Tokaido Shinkansen trainsets as well as 12-, 8-, and 6-car configurations, improving flexibility for potential export.[3][6][7]

Green cars feature a fully active damping control system to improve ride quality, while ordinary-class cars provide AC power outlets at every seat.[3][8] Additional improvements include larger luggage storage areas, more CCTV cameras, an upgraded intercom system, and softer, more relaxing interior lighting.[9]

In 2021, the N700S was awarded the Laurel Prize by the Japan Railfan Club.[10]

JR Central

A 16-car prototype set (J0), assembled at the Nippon Sharyo Toyokawa plant, was unveiled at JR Central's Hamamatsu depot on 10 March 2018.[6] From 20 March, this set was used for testing and evaluation.[6] High-speed trials at the design speed of 360 km/h (224 mph) were conducted during 2019 on the Tokaido Shinkansen, reaching a maximum speed of 363 km/h (226 mph).[11] This is 28 km/h (17 mph) faster than the fastest speed ever achieved by the N700A, and may indicate plans to raise the maximum operating speed on the line.[2]

The first full-production J set (J1) was delivered to JR Central in April 2020, with trains entering revenue service on 1 July 2020.[8]

JR Central announced in May 2022 that it would add 19 trainsets (304 vehicles) to their current N700S fleet at a cost of 114 billion yen ($897m).[12][4] The first two of these trainsets are scheduled to enter service in 2023, with seven trainsets delivered in 2024 and 2025, and three more delivered in 2026.[4]

In June 2024, JR Central announced that the Doctor Yellow inspection trains would be replaced by stock-standard N700S trainsets with special monitoring equipment from 2027.[13]

In January 2026, JR Central announced that they would begin to introduce private rooms on N700S Nozomi trains starting in October 2026. Two private rooms will initially be offered on selected services, each seating one or two passengers. The rooms will be priced higher than green car seats. It will mark the first time that private rooms will be available on the Tōkaidō Shinkansen since the retirement of the 100 Series Shinkansen in 2003. JR Central has also planned to introduce semi-private rooms in fiscal year 2028.[14]

JR Kyushu

As of December 2024, the Nishi Kyushu Shinkansen is operated by a fleet of five 6-car JR Kyushu N700S series trainsets.

For the commencement of the Nishi Kyushu Shinkansen, four 6-car N700S series trainsets were ordered by JR Kyushu.[15][16] Nicknamed "Kamome", these entered service in September 2022.[17][18] Two trains are required during the day, with three trains in operation in the afternoon/evening. One train is kept as a spare.

In August 2023, another 6-car set was delivered to allow for one train to be out of service during regular inspections.[19]

Operations

The first N700S sets replaced 700 series trains, and added more rolling stock needed to realize the increased amount of services on the Tokaido Shinkansen planned from 2020.[20][21] The N700S series is expected to gradually replace N700 series sets on the Sanyo, Tokaido, and Kyushu Shinkansen lines. A 6-car variant started operations on the Nishi Kyushu Shinkansen on 23 September 2022.[18][17]

The train is also planned to run on the proposed Texas Central Railway high-speed line connecting Dallas and Houston.[22]

6-car Y sets (N700S-8000 series)

N700S-8000 series set Y4 on the Nishi Kyushu Shinkansen in October 2022

These are 6-car N700S series sets owned by JR Kyushu and classified as N700S-8000 series sets. Five sets provide service on the Nishi Kyushu Shinkansen.[23]:197

The design of the variant was done by Eiji Mitooka, who had previously designed several trains for JR Kyushu.[27] He could not make any modifications to the exterior shape or equipment. He sought to make the ride "more fun and relaxing" through the inclusion of colors and shapes to the train's design. He presented JR Kyushu with four livery concepts, with a red and white one being chosen. Headlights were given black outlines and the center of the nose was painted black in order to have the front of the train resemble a face. The interior is also decorated with illustrations made by Mitooka.

These sets do not feature Green Car (first class) accommodation. In regular service, cars 1-3 are reserved seat cars, and cars 4-6 are non-reserved seat cars. Seats on cars 1–3 are arranged in four wide (2+2) abreast configuration instead of a five wide (2+3) configuration seen in normal reserved cars of JR West and JR Central N700S variants, and similar to reserved seat cars on JR Kyushu's N700 series sets. This was done to make the Shinkansen more attractive to tourists.[27]

Derivatives

In March 2023, Taiwan High Speed Rail announced it will purchase 12 new 12-car trains based on the N700S at a cost of approximately NTD 28 billion to supplement its older THSR 700T sets.[29][30] These will be manufactured by an alliance of Hitachi and Toshiba.[30] In August 2025, these new trains were officially designated as the N700ST series. The first set of the new trains is expected to arrive in Taiwan in August 2026 and revenue service will start in the second half of 2027.[31]
