The Aizu Liner (あいづライナー) was a limited-stop "Rapid" train service in Japan operated by the East Japan Railway Company (JR East) between Kōriyama and Aizu-Wakamatsu on the Banetsu West Line in Fukushima Prefecture.

[2] Kōriyama - Kikuta - Bandai-Atami - Inawashiro - Bandaimachi - Aizu-Wakamatsu Services are normally formed of a 6-car 485 series limited express-type electric multiple unit (EMU) set number G55/58 based at Sendai Depot, sometimes substituted by a 6-car 583 series EMU (set N1/2).

[1] In June 2011, the Sendai-based 6-car 485 series EMU set A1/2 normally used on Aizu Liner services was repainted from its previous "Akabē" livery into JNR beige and maroon, returning to service from 2 June 2011.

[3] Regular Aizu Liner services were discontinued from the start of the revised timetable introduced on 14 March 2015.

[6] Seasonal rapid services, named simply Aizu operate during busy holiday periods, which used six-car 485 series EMU trainsets until the timetable revision in March 2020, at which point the service began to be operated with E721 series EMUs equipped with a reserved seat section.
