The {{Nihongo|'''817 series'''|817系}} is an AC [[electric multiple unit]] (EMU) train type operated on commuter and local services by [[Kyushu Railway Company]] (JR Kyushu) in Japan since 2001. The design was based on the earlier [[815 series]], with transverse seating replacing the previous longitudinal seating,<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|title=Jēāru zensharyō handobukku: Rail Magazine 2009}}</ref> although later variants reverted to longitudinal seating.
==Variants== There are five sub-series variants, 817-0, 817-1000, 817-1100, 817-2000, and 817-3000 series, allocated to five depots, Kagoshima, Kumamoto, Minami-Fukuoka, Nagasaki, and Nōgata.
