The E6 series (E6系) is a Japanese Shinkansen high-speed train type on order by East Japan Railway Company (JR East) for use on Komachi 'mini-shinkansen' services on the Tōhoku Shinkansen and Akita Shinkansen from Tokyo to Akita commencing in March 2013. The new 7-car trains will operate in conjunction with newly introduced E5 series trains, initially on just two or three return services daily. They will replace all the existing E3 series trains on Komachi services by March 2014.[1]
Technology incorporated in these trains is derived from the experimental Fastech 360Z train previously tested by JR East. The E6 series trains are formed of seven cars, to provide the same seating capacity as six-car E3 series trains, due to the reduced seating capacity in the end cars. All cars feature active suspension with tilting up to 1.5 degrees.[2]

The pre-production train, S12, is formed as follows, with car 11 at the Tokyo end and car 17 at the Akita end.[3]

Cars 11 to 14 were built by Kawasaki Heavy Industries, and cars 15 to 17 were built by Hitachi.[4]
The overall styling was overseen by Japanese industrial designer Ken Okuyama, and is intended to evoke images of the Namahage demons and kantō festival lanterns for which Akita Prefecture is famous.[5] The main body colour is "Hiun" (飛雲) white with crimson roof and "arrow silver" bodyside stripe. The end cars are 23,075 mm (75 ft 8.5 in) long with the tapered nose accounting for approximately 13 m (compared with approximately 6 m for the E3 series).[2]
The new trains feature similar improvements to passenger accommodation as featured on the E5 series trains, including AC power outlets, and security cameras in vestibule areas. Seating in both Standard class and Green (first class) cars is in the standard 2+2 arrangement for mini-shinkansen trains.[1] Seat pitch is 1,160 mm (46 in) in Green class and 980 mm (39 in) in Standard class, the same as for the E3 series trains.[2]
The pre-production set, S12, was delivered to Sendai Depot in June 2010.[6] Test running commenced on the Tōhoku Shinkansen in July 2010.[7]
Revenue service is scheduled to commence in March 2013, running at a maximum speed of 300 km/h (186 mph) on the Tōhoku Shinkansen.[2] From March 2014, the maximum speed will be raised to 320 km/h (199 mph) on the Tōhoku Shinkansen, with the maximum speed on the Akita Shinkansen tracks remaining at 130 km/h (81 mph), allowing journey times between Tokyo and Akita to be reduced by between 10 and 15 minutes.[1]
