The 789 series (789系?) is an AC electric multiple unit train type operated by Hokkaido Railway Company (JR Hokkaido) on limited express services in Hokkaido, Japan, since 2002. Two variants exist: the original 789 series for use on Super Hakuchō services, and the 789-1000 series for use on Super Kamui services.[1]

Super Hakuchō 789 series

A total of 34 cars were built between 2000 and 2005 for use on new Super Hakuchō services introduced from 1 December 2002 between Hachinohe (Shin-Aomori from December 2010) and Hakodate via the undersea Seikan Tunnel coinciding with the opening of the Tōhoku Shinkansen extension to Hachinohe.[2]

The trainsets are formed of ten 3-car half-sets, HE-101–105 and HE-201–205, with two additional 2-car sets, HE-301 and HE-302, available for extending trains to up to eight cars during period seasons.[3]

Super Kamui 789-1000 series

Seven 5-car 789-1000 series sets, HL-1001–1007, were delivered to Sapporo Depot between June and September 2007, and these entered service from 1 October 2007 on new Super Kamui limited express services between Sapporo and Asahikawa, and on Airport rapid services between Sapporo and New Chitose Airport in conjunction with 785 series EMUs. These replaced the Lilac services formerly operated by 781 series EMUs.[3][2]

The 789-1000 sets differ from the earlier Super Hakuchō sets in not having gangway doors beneath the driving cabs.[1]
