The {{Nihongo|'''E751 series'''|E751系}} is an [[Alternating current|AC]] [[electric multiple unit]] (EMU) train type operated on ''[[Tsugaru (train)|Tsugaru]]'' [[limited express]] services in the north of Japan by [[East Japan Railway Company]] (JR East) since March 2000. The design was based on the earlier (1,500 V DC) [[E653 series]] EMUs, with improvements to cope with colder weather conditions in the north of Japan.<ref name="neko2009">{{cite book| script-title=ja: JR全車輌ハンドブック2009 |trans-title=JR Rolling Stock Handbook 2009| publisher = Neko Publishing| year = 2009| location = Japan| isbn = 978-4-7770-0836-0}}</ref>

==History== [[File:JR East E751 hatsukari.jpg|thumb|An E751 series EMU at Aomori Station on a ''Super Hatsukari'' service in 2002]] The first set was delivered to Aomori Depot from [[Japan Transport Engineering Company|Tokyu Car Corporation]]'s Yokohama factory on 9 December 1999, followed by the remaining two sets in January 2000. The fleet entered service on ''[[Hatsukari|Super Hatsukari]]'' services operating between {{STN|Morioka|x}} and {{STN|Aomori|x}} from the start of the revised timetable on 11 March 2000.<ref name="jrr2010"/>

From 1 December 2002, the E751 series trains were reassigned to new ''[[Tsugaru (train)|Tsugaru]]'' services operating between {{STN|Hachinohe|x}} and {{STN|Hirosaki|x}}, which replaced the former ''Super Hatsukari'' services following the opening of the [[Tōhoku Shinkansen]] extension from Morioka to Hachinohe.<ref name="haraguchi2009">{{cite book| last = Haraguchi| first = Takayuki| script-title=ja: Encyclopedia of JR's Railway Cars: ＪＲ全車輌| publisher = Sekai Bunka| year = 2009| location = Japan| page = 50| isbn = 978-4-418-09905-4}}</ref>
