The E7 series (E7系?) is a Japanese Shinkansen high-speed train type operated by East Japan Railway Company (JR East) on the Hokuriku Shinkansen since 15 March 2014.
Jointly developed alongside the similar JR West W7 series, the first E7 series trains were delivered in late 2013.
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. The bodyside logos consist of a number "7" in silver stylized as an arrowhead, and include the lettering "East Japan Railway Company".

Manufacture of the E7 series sets was 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.
