The {{Nihongo|521 series|521系|521-kei}} is a dual-voltage AC/DC outer-suburban electric multiple unit (EMU) train type operated by West Japan Railway Company (JR West) and third-sector railway operators IR Ishikawa Railway and Ainokaze Toyama Railway on local services in the Fukui and Kanazawa areas since November 2006.{{cite book| last = Haraguchi| first = Takayuki| script-title=ja: Encyclopedia of JR's Railway Cars: ＪＲ全車輌| publisher = Sekai Bunka| date = 2009| location = Japan| page = 90| isbn = 978-4-418-09905-4| title = Jr全車両: ビジュアル決定版}} In March 2024, Hapi-line Fukui acquired some sets after taking over the section of the Hokuriku Main Line within Fukui Prefecture from JR West.{{Cite web |title=福井県並行在来線経営計画 |trans-title=Fukui Prefecture Parallel Conventional Line Management Plan |url=https://www.hapi-line.co.jp/files/uploads/management_plan_202111.pdf |archive-url=https://web.archive.org/web/20231216150530/https://www.hapi-line.co.jp/files/uploads/management_plan_202111.pdf |archive-date=16 December 2023 |access-date=16 March 2024 |website=hapi-line.co.jp |language=ja}}

Design

The 521 series was the first dual-voltage suburban EMU type to be built for JR West. The body of the first two batches was based on the 223-5000 series suburban EMU design, with the same WMT102C {{Convert|230|kW|4=0|abbr=on}} traction motors.{{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|title= Jēāru zensharyō handobukku: Rail Magazine 2009}} The sets are able to be used on wanman driver-only operation services.
