The {{Nihongo|'''E257 series'''|E257系|E257-kei}} is a [[Direct current|DC]] [[electric multiple unit]] (EMU) train type operated in Japan for limited express services by [[East Japan Railway Company]] (JR East) and built jointly by [[Hitachi]], [[Kinki Sharyo]], and [[Tokyu Car Corporation]].

==Variants== * '''E257-0 series''': ''[[Azusa (train)|Azusa]]'', ''[[Kaiji (train)|Kaiji]]'' * '''E257-500 series''': ''[[Sazanami (train)|Sazanami]]'', ''[[Wakashio]]'', ''[[Shiosai]]'', ''[[Ayame (train)|Ayame]]'' * '''E257-2000/-2500 series''': ''[[Odoriko]]'', ''[[Shōnan (train)|Shōnan]]'' * '''E257-5000 series''': additional services * '''E257-5500 series''': ''[[Akagi (train)|Akagi]]'', ''[[Kusatsu (train)|Kusatsu/Shima]]''

Four variants exist: the original E257-0 series for use on [[Chūō Main Line]] ''[[Azusa (train)|Azusa]]'' and ''[[Kaiji (train)|Kaiji]]'' limited-express services until 16 March 2019 (displaced by [[E353 series]] EMUs), the E257-500 series for use on Chiba area limited express services ([[Uchibō Line|Uchibo Line]] ''[[Sazanami (train)|Sazanami]]'', [[Sotobō Line|Sotobo Line]] ''[[Wakashio]]'', [[Sōbu Main Line]] ''[[Shiosai]]'', and [[Narita Line|Narita]] and [[Kashima Line]]s ''[[Ayame (train)|Ayame]]''),<ref name="neko2009">{{cite book |title= |publisher=Neko Publishing |year=2009 |isbn=978-4-7770-0836-0 |location=Japan |pages=149–151 |language=ja |script-title=ja: JR全車輌ハンドブック2009 |trans-title=JR Rolling Stock Handbook 2009}}</ref> the E257-2000/-2500 used for ''[[Odoriko]]'' services modified from former E257-0 and -500 series trains, and the E257-5000/5500 from former E257-0 and -500 trains for use on additional and charter services.{{citation needed|date=July 2019}}

Based at [[Matsumoto, Nagano|Matsumoto]] depot, the fleet consisted of sixteen 9-car sets (M101 to M116) with a full cab at the Matsumoto end and a [[Gangway connection|gangwayed]] cab at the Tokyo end, and five 2-car "add-on" sets (M201 to M205) with a full cab at the Tokyo end and a shunting cab at the Matsumoto end.

The type was the recipient of the 45th [[Blue Ribbon Award (railway)|Blue Ribbon Award]] (2002) of the Japan Railfan Club.

From 2018, the E257 series trains were replaced by [[E353 series]] EMUs on Chuo Main Line ''Azusa'' and ''Kaiji'' limited express services.<ref name="sankei201710292">{{cite web |date=29 October 2017 |title= |script-title=ja: 来年3月に現行車両「E351系」引退スーパーあずさ、新型に |trans-title=E351 series to be retired by next spring with new trains for "Super Azusa" services |url=http://www.sankei.com/photo/story/news/171029/sty1710290001-n1.html |url-status=live |archive-url=https://web.archive.org/web/20171122024916/http://www.sankei.com/photo/story/news/171029/sty1710290001-n1.html |archive-date=22 November 2017 |access-date=22 November 2017 |work=Sankei Photo |publisher=The Sankei Shimbun & Sankei Digital |language=ja |location=Japan}}</ref> From the start of the revised timetable on 16 March 2019, E257 series trains were no longer used on regular Chuo Main Line limited express services. The trains were modified into E257-2000 series trainsets and redeployed on [[Tōkaidō Main Line|Tokaido Main Line]] ''[[Odoriko]]'' services from 14 March 2020. Several sets are still under refurbishment and three sets, which were reserved for use on charter and extra services, were modified into E257-5000s. As a result of these conversions, the five 2-car "add-on" sets were deemed surplus and therefore scrapped.<ref>{{Cite web |date=2023-03-30 |title= |script-title=ja:活躍は第2章へ定期も臨時もこなす「オールラウンダー」E257系の今後は？ |trans-title=Continuing to chapter 2: What's next for the "all-rounder" E257 series? |url=https://rail.hobidas.com/feature/453514/ |url-status=live |archive-url=https://web.archive.org/web/20230401152833/https://rail.hobidas.com/feature/453514/ |archive-date=1 April 2023 |access-date=2023-04-01 |website=RM News |publisher=Neko Publishing |language=ja |publication-place=Japan}}</ref>
