So it looks as if the new E5 will be based somewhat on the Fastech 360...
Ill try and get more pictures as I find them.



The E5 Series Shinkansen are 10-car high-speed trainsets currently on order by East Japan Railway Company (JR East) for use on Hayate services on the Tōhoku Shinkansen from Tokyo to Shin-Aomori commencing in 2011. A total of 59 sets are on order.[1]

Technology incorporated in these trains will be derived from the experimental Fastech 360S train tested by JR East. Maximum speed will be 320 km/h, although services will initially run at a maximum speed of 300 km/h until 2013.[2]

Car 10 (at the Aomori end) will be designated a "Super Green Car" (provisional name), featuring 18 power-reclining "shell" seats in 2+1 abreast configuration. Seat pitch will be 1,300 mm compared to 1,160 mm for conventional Green Car (first class) seating.[3]

According to details released by JR East in February 2009, the exterior design of the trains will be broadly based on the experimental Fastech 360S train, with a colour scheme of "Tokiwa" (常盤 ?) green for the upper body and "Hiun" (飛雲 ?) white for the lower body, separated by a "Hayate" pink stripe.[4]
