The 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,[2] although later variants reverted to longitudinal seating.
