The 489 series (489系, 489-kei) was a limited express electric multiple unit (EMU) train type introduced in March 1972 by Japanese National Railways (JNR) in Japan, and later operated by East Japan Railway Company (JR East) and West Japan Railway Company (JR-West) until 2012.

[1] The 489 series trains were developed from the earlier 485 series specially for use on the Hakusan and Asama limited express services operating over the steeply graded Usui Pass (Yokokawa Station - Karuizawa Station of old JNR Shinetsu Main Line).

They were designed to operate in multiple with the JNR Class EF63 electric banking locomotives.
