N700 Series Shinkansen The N700 Series Shinkansen is a family of high-speed electric multiple unit trains developed for service on Japan’s premier high-speed lines, built to succeed earlier Shinkansen models such as the 700 Series Shinkansen and 100 Series Shinkansen. Introduced in 2007, the N700 family was deployed by Central Japan Railway Company, West Japan Railway Company, and Kyushu Railway Company to provide faster acceleration, improved energy efficiency, and enhanced passenger comfort on routes including the Tōkaidō Shinkansen, Sanyō Shinkansen and Kyushu Shinkansen.
Overview
The N700 family emerged from collaborative programs among major Japanese manufacturers including Hitachi, Kawasaki Heavy Industries, and Nippon Sharyo for operators such as JR Central, JR West, and JR Kyushu. It was designed to meet demands set by the Ministry of Land, Infrastructure, Transport and Tourism for improved timetable resilience on busy corridors like the Tōkaidō Shinkansen and for compatibility with international standards exemplified by projects such as the World Expo-era rail improvements. Derivative objectives included interoperability with existing infrastructure originally built for earlier types like the 300 Series Shinkansen and fleet lifecycle management strategies used by Japan Railways Group companies.
Design and Development
Development of the N700 series drew on research from institutions including the Japan Railway Technical Research Institute and design input from manufacturers with experience on models like the E5 Series Shinkansen and E6 Series Shinkansen. Key engineering goals were higher acceleration to reduce schedule padding used across the Tōkaidō and Sanyō corridors, active suspension systems influenced by research at University of Tokyo, and improved aerodynamics to reduce tunnel micro-pressure waves first addressed on the 700 Series Shinkansen. The trains feature distributed power with powered cars at multiple positions, traction equipment sourced from corporate groups such as Mitsubishi Electric and Toshiba, and braking technologies developed with suppliers like Hitachi Rail STS.
Variants and Formations
Several N700 variants were produced: the original production N700 used by JR Central in 16-car formations for Nozomi services; the N700A ("Advanced") upgrade introduced additional safety and performance features for JR Central and JR West; the 8-car N700-7000/8000 variants built for JR West and JR Kyushu for Sakura and Tsubame services on the Kyushu Shinkansen; and hybrid formations used in through-running arrangements linking Sanyo and Kyushu lines. Formation patterns are standardized into 8-car and 16-car sets with specific car types for driving, powered, and trailer roles, and interior layouts configurable for Gran Class, Green Car, and ordinary-class seating, reflecting service branding similar to that on Nozomi and Hikari services.
Operations and Services
N700 units operate on flagship services including Nozomi, Hikari, Sakura, and Tsubame services, providing high-frequency links among metropolitan areas such as Tokyo, Nagoya, Osaka, and Hakata. Their deployment enabled timetable acceleration measures coordinated with operators during events like the 2015 G7 Summit and capacity expansions aligned with infrastructure projects such as platform extensions at Shin-Osaka Station. Inter-service compatibility allowed N700s to run alongside legacy fleets such as the N700-7000 Series and cooperate with traffic management systems used by JR Central and JR West.
Technical Specifications
Typical N700 specifications include 16-car or 8-car formations, 25 kV AC / 50 Hz (Tōkaidō/Sanyō) collection via pantographs, and maximum service speeds up to 300 km/h on conventional Shinkansen lines; design features include active suspension, yaw dampers, and distributed traction motors achieving improved acceleration compared with the 700 Series Shinkansen. On-board systems integrate automatic train control using variations of ATC-NS and regenerative braking supplied by equipment manufacturers such as Mitsubishi Electric. Carbody materials employ aluminum alloy techniques similar to those used by Nippon Sharyo in other high-speed EMUs, with noise reduction measures adapted from research by Central Research Institute of Electric Power Industry.
Safety, Upgrades and Performance
Safety enhancements in the N700A upgrade included revised bogies, improved braking control, and enhanced earthquake detection interoperability with regional systems like the UrEDAS-type devices and national directives from the Ministry of Land, Infrastructure, Transport and Tourism. Continuous improvements have addressed wheel/rail interaction studied by Railway Technical Research Institute and energy-saving measures informed by collaborations with Chubu Electric Power research. Performance monitoring programs led by JR Central and JR West collect operational data to optimize maintenance schedules at depots such as Nagoya Depot and Hineno Depot, supporting long-term reliability targets similar to those for earlier fleets including the 0 Series Shinkansen.
Preservation and Cultural Impact
Several N700-series vehicles and mock-ups have appeared in museums and exhibitions at institutions such as the SCMaglev and Railway Park and in promotional events organized by Central Japan Railway Company and West Japan Railway Company. The N700 family influenced postgraduate research at universities like Tokyo Institute of Technology and inspired model railway releases by companies including Kato Works and TOMIX, contributing to popular culture portrayals alongside icons like Shinkalion and exhibitions at venues like Tokyo Big Sight. Its role in modernizing intercity travel continues to be featured in technical publications from organizations such as the Japan Society of Mechanical Engineers and in transport policy discussions within the Ministry of Land, Infrastructure, Transport and Tourism.
