E6 Series Shinkansen

The E6 series (Japanese: E6系) is a Japanese Shinkansen high-speed train type. It operates exclusively on Komachi services on the Akita Shinkansen, a mini-Shinkansen line between Akita and Morioka, at speeds of up to 130 kilometres per hour (81 mph). From Morioka, services continue to and from Tokyo on the Tōhoku Shinkansen, where the train is coupled or uncoupled from a Hayabusa service operated with an E5/H5 series train. Compared with the E3 series it replaced, the E6 series can operate at up to 320 kilometres per hour (200 mph) on the Tōhoku Shinkansen, up from 275 kilometres per hour (171 mph), reducing journey times by an average of 12 minutes. The trains were designed by Ken Okuyama.

A total of 24 seven-car trainsets were built by Hitachi and Kawasaki Heavy Industries between 2012 and 2014. The first set, numbered G1, was delivered in June 2010.
