The E7 series (E7系, E-nana-kei) and W7 series (W7系, Daburu-nana-kei) Shinkansen are Japanese high-speed electric multiple unit train types operated on the Hokuriku and Jōetsu Shinkansen lines, and jointly developed by East Japan Railway Company (JR East) and West Japan Railway Company (JR West) respectively.

[6] Manufacture of the E7 and W7 series sets was shared between Hitachi in Kudamatsu, Yamaguchi and Kawasaki Heavy Industries in Kobe;[7] additionally the E7 in J-TREC in Yokohama, and W7 in Kinki Sharyo in Osaka.

[2] 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.

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 Hokuriku Shinkansen (then still called the Nagano Shinkansen) between Tokyo and Nagano.

[1] Since 14 March 2015, with the opening of the Hokuriku Shinkansen extension from Nagano to Kanazawa, E7 series trainsets are also used on Hakutaka, Kagayaki, and Tsurugi services alongside the similar design JR West W7 series trains.

The luggage racks are to cater to the increased number of overseas tourists with suitcases and also passengers with ski and snowboard equipment in the winter season.

[28] In January 2012, the head of JR-West's Kanazawa Division revealed that new trains for the Hokuriku Shinkansen would be developed in conjunction with JR East, and that test running would need to be conducted during the winter season a year before the line opening to thoroughly test the ability of the trains to cope with snowy conditions.

[6] The first three trains, sets F1 to F3, entered regular passenger service from the start of the revised JR East timetable on 15 March 2014.

[3] Test-running on the Hokuriku Shinkansen began on 5 August 2014, initially at low speed, between Kanazawa and Jōetsumyōkō.

[33] In April 2015, JR East announced that it was ordering an additional E7 series set to be introduced from autumn 2015, replacing the remaining E2 series trainsets used on regularly scheduled Hokuriku Shinkansen Asama services.
