The E6 series (E6系) is a Japanese Shinkansen high-speed train type operated by East Japan Railway Company (JR East) on Komachi "mini-shinkansen" services on the Tōhoku Shinkansen and Akita Shinkansen from Tokyo to Akita since 16 March 2013. A pre-series set was delivered in June 2010 for extensive testing, with 23 full-production sets delivered between November 2012 and spring 2014.
The 7-car E6 series trains operate in conjunction with E5 series or H5 series (since March 2016) 10-car trains, initially on just four return services daily from 16 March 2013.They replaced all of the previous E3 series trains on Komachi services by 15 March 2014.
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.
The pre-series train, numbered "S12" (later becoming "Z1"), was formed as follows, with car 11 at the Tokyo end and car 17 at the Morioka end.
The full-production trains, numbered "Z2" onward, are formed as follows, with car 11 at the Tokyo end and car 17 at the Morioka end.
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. "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).The main body colour is
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. 1,160 mm (46 in) in Green class and 980 mm (39 in) in Standard class, the same as for the E3 series trains. Cars 12, 13, 14, and 16 are equipped with toilets. The toilet in car 12 is universal access.Seat pitch is
The pre-series set, S12, was delivered to Sendai Depot in June 2010,and formally accepted by JR East on 8 July. Test running commenced on the Tohoku Shinkansen in July 2010.
The first full-production set was delivered in November 2012, with production continuing until spring 2014.
Revenue service commenced on 16 March 2013 on new Super Komachi services, running at a maximum speed of 300 km/h (185 mph) on the Tohoku Shinkansen. From 15 March 2014, the maximum speed was raised to 320 km/h (200 mph) on the Tohoku Shinkansen, with the maximum speed on the Akita Shinkansen tracks remaining at 130 km/h (80 mph), allowing journey times between Tokyo and Akita to be reduced by an average of 12 minutes. The service name was also returned to simply Komachi.
In May 2014, the E6 series was awarded the 2014 Laurel Prize, presented annually by the Japan Railfan Club.The award presentation ceremony was held at Akita Station on 8 November 2014.
As of 1 October 2014 [update] , 24 sets were in service, as shown below.

While the first sets from both Hitachi and Kawasaki Heavy Industries were delivered by sea to Sendai, set Z9 was delivered from the Kawasaki Heavy Industries factory in Kobe by rail to Akita Depot over three days from 31 May to 2 June 2013, mounted on temporary narrow-gauge (1,067 mm gauge) bogies and hauled by freight locomotives. This was followed by set Z11 from 21 to 23 June 2013.
The 100 series was a Japanese Shinkansen high-speed train type which operated between 1985 and 2012 on the Tokaido Shinkansen and Sanyo Shinkansen high-speed lines. They were introduced after the 200 series trains, but their numbering is such because in the days of Japanese National Railways (JNR), Shinkansen types running east of Tokyo were given even numbers and those west of Tokyo odd numbers, hence they were given the next odd number in line after 0, 100. The last remaining examples of the type were withdrawn from service following the last runs on 16 March 2012.
The 200 series (200系) was a Shinkansen high-speed train type introduced by Japanese National Railways (JNR) for the Tohoku Shinkansen and Joetsu Shinkansen high-speed rail lines in Japan, and operated by East Japan Railway Company until 2013. They actually predated the 100 series trains, having been built between 1980 and 1986. It was one of the two recipients of the 23rd Laurel Prize presented by the Japan Railfan Club, the first Shinkansen type to receive that award. The last remaining sets were retired from regular service in March 2013, and were completely withdrawn from service in April 2013.
The 400 series (400系) was a Japanese Shinkansen high-speed train type operated by East Japan Railway Company between 1992 and 2010 on Tsubasa services on Japan's first mini-shinkansen line, the Yamagata Shinkansen branch from the main Tohoku Shinkansen.
The E1 series (E1系) was a high-speed Shinkansen train type operated by East Japan Railway Company in Japan from July 1994 until September 2012. They were the first double-deck trains built for Japan's Shinkansen. They were generally, along with their fellow double-deck class the E4 series, known by the marketing name "Max". The fleet was withdrawn from regular service on 28 September 2012.
The E2 series is a Japanese high-speed Shinkansen train type operated by East Japan Railway Company on the Tohoku Shinkansen high-speed lines in Japan since 1997. They are formed in 8- and 10-car sets. The 8-car sets were used on the Hokuriku Shinkansen, and the 10-car sets are on Tohoku Shinkansen services. The 10-car sets can be coupled to E3 series Komachi sets using couplers hidden behind retracting nose doors.
The E3 series (E3系) is a Japanese Shinkansen high-speed train type built for Komachi services which commenced on 3 June 1997, coinciding with the opening of the new Akita Shinkansen "mini-shinkansen" line, a regular 1,067 mm narrow-gauge line between Morioka and Akita re-gauged to 1,435 mmstandard gauge. Later versions of the E3 series were also introduced for use on Yamagata Shinkansen Tsubasa services. Both "mini-shinkansen" lines join the Tohoku Shinkansen, providing services to and from Tokyo.
The Komachi (こまち) is a high-speed shinkansen service between Tokyo and Akita in Japan, operated by the East Japan Railway Company since March 1997. It is the only shinkansen service that runs on the Akita Shinkansen, and uses E6 series trains. Between Tokyo Station and Morioka, it couples with Tōhoku Shinkansen E5 series Hayabusa and formerly E2 series for E3 series. After Morioka, the Komachi service continues along standard gauge tracks that were converted from narrow gauge. Because it then runs on tracks that have grade crossings, its maximum speed from Morioka to Akita is 130 km/h (80 mph), compared to 320 km/h (200 mph) on the Tohoku Shinkansen.
Hayate (はやて) is a high-speed Shinkansen service operated in Japan, on the Tohoku Shinkansen by East Japan Railway Company since 2002 and on the Hokkaido Shinkansen by JR Hokkaido since 26 March 2016. It operates as far as the northern terminus of Shin-Hakodate-Hokuto, and it is the second-fastest service on the Tohoku Shinkansen. These services were inaugurated with the opening of the Tohoku Shinkansen extension to Hachinohe on 1 December 2002.
The Akita Shinkansen (秋田新幹線) is a Mini-shinkansen rail line in Japan. Serving the Kantō and Tōhoku Regions of the country, it links Tokyo and Akita in Akita prefecture. From Tokyo to Morioka in Iwate prefecture, it operates on the Tōhoku Shinkansen tracks. From Morioka to Ōmagari, it uses the Tazawako Line tracks. The section from Ōmagari to Akita use the Ōu Main Line tracks.
The N700 series is a Japanese Shinkansen high-speed train with tilting capability developed jointly by JR Central and JR West for use on the Tokaido and San'yō Shinkansen lines since 2007, and also operated by JR Kyushu on the Kyushu Shinkansen line.
The E5 series (E5系) is a Japanese Shinkansen high-speed train type operated by East Japan Railway Company on Tōhoku Shinkansen services since 5 March 2011 and on Hokkaido Shinkansen services since 26 March 2016.

The HB-E300 series (HB-E300系) is a hybrid diesel multiple unit (DMU) train type operated by East Japan Railway Company on "resort train" services on scenic lines in Japan since October 2010.
"WIN350" was the name given to the 500-900 series (500系900番代) 6-car experimental high-speed Shinkansen train developed in 1992 by the West Japan Railway Company in Japan to test technology to be incorporated in next-generation shinkansen trains expected to operate at speeds of 350 km/h (217 mph) from 1994. Initially given the designation "500X", the name "WIN350" stood for "West Japan's Innovation for operation at 350 km/h".
The E7 series (E7系) and W7 series Shinkansen are Japanese high-speed train types operated by East Japan Railway Company and West Japan Railway Company (JR-West), respectively. They were jointly developed.
