The E7 series (E7系?) is a Japanese Shinkansen high-speed train type operated by East Japan Railway Company (JR East) on the Nagano Shinkansen since 15 March 2014. It will also be used on the Hokuriku Shinkansen when the line is extended from Nagano to Kanazawa in March 2015.
Based on the earlier E2 series trains, the E7 series trains are designed with a "Japanese" theme inside and out, combining futuristic styling with traditional design elements overseen by industrial designer Ken Okuyama together with Kawasaki Heavy Industries. Externally, the roof is finished in a "sky blue" colour, and the bodysides are "ivory white" with "copper" and "sky blue" lining. Manufacture of the E7 series sets is being shared between Hitachi in Kudamatsu, Yamaguchi, J-TREC in Yokohama, and Kawasaki Heavy Industries in Kobe. J-TREC is building five E7 series sets (60 vehicles), starting in July 2013.
The trains have a maximum design speed of 275 km/h (170 mph), but operate at a maximum speed of 260 km/h (160 mph) on the Hokuriku Shinkansen, limited to 240 km/h (150 mph) on the Joetsu Shinkansen tracks between Omiya and Takasaki, and to 110 km/h (70 mph) on the Tohoku Shinkansen tracks between Tokyo and Omiya. Increased power output enables the trains to maintain speeds of at least 210 km/h (130 mph) on the steep gradients of the Hokuriku Shinkansen.
- Asama (Tokyo - Nagano), since March 2014
The trains entered regular passenger service from the start of the revised JR East timetable on 15 March 2014, with three trainsets introduced on Asama services on the Nagano Shinkansen between Tokyo and Nagano. Initially, E7 series trainsets operated seven return Asama services daily, with a further four return workings added from 19 April 2014.
The 12-car sets are numbered "F1" onward, and consist of 10 motored intermediate cars with non-powered (trailer) end cars. Car 11 provides Green car (first class) accommodation, and car 12 provides Gran Class luxury accommodation. Sets are formed as shown below, with car 1 at the Tokyo end.

The 12-car trains have accommodation in three levels of service: Gran Class, Green car, and Standard cars, with a total seating capacity of 934. Gran Class seating (car 12) is arranged 2+1 abreast with a seat pitch of 1,300 mm (51 in), Green car seating (car 11) is arranged 2+2 abreast with a seat pitch of 1,160 mm (46 in), and ordinary seating (cars 1 to 10) is arranged 3+2 abreast with a seat pitch of 1,040 mm (41 in). AC power outlets are provided for each seat in all three classes. The Gran class seats are supplied by Toyota Boshoku. Car saloons and vestibule areas are equipped with security cameras.
In December 2011, it was reported that JR East was considering developing new E7 series 10-car sets based on the existing E2 series design for use on Hokuriku Shinkansen services. Details of the new trains were formally announced jointly by JR East and JR West on 4 September 2012. The first E7 series train was delivered to Sendai Depot in November 2013, and shown off to the media on 28 November. Night-time testing commenced in December on the Nagano Shinkansen, with daytime test-running between Nagano and Tokyo starting on 8 January 2014. The design of the logo to be applied to the sides of cars 1 and 12 was officially unveiled in February 2014. Consisting of a number "7" in silver stylized as an arrowhead, the logo includes the lettering "East Japan Railway Company".
The first trains entered regular passenger service from the start of the revised JR East timetable on 15 March 2014, with five E7 series sets scheduled to be delivered during fiscal 2013 (i.e. by the end of March 2014).
