Kato Newa
The E6 series began commercial operation in March 2013 as a new type of train for the Akita Shinkansen. Between Tokyo and Morioka, it is coupled with the E5/H5 series Shinkansen and operates at the maximum domestic commercial speed of 320km/h. In recent years, with the increase in foreign travelers carrying large luggage, the train was modified to install large luggage storage areas between February and August 2018, and some of the windows in cars 13, 15, and 17 were filled in. Similar work was then carried out on cars 12, 14, and 16, eventually spreading to all cars except car 11 (Green Car).
