History
Eda Station has an unusually long history of advocacy. It opened on 10 October 1917 as Eda Signal Box on the Ban'etsu East Line at a point on a 15.2-permille grade, making promotion to a full station prohibitively expensive (~300,000 yen, the cost of switchback construction). Seasonal autumn-foliage stops began in 1930 and continued through the wartime period despite the signal box itself being abolished in 1933. From 1 October 1948 the site reopened as a flag stop (kari-jōkōjō), with all local trains stopping from 1967. From August 1978 commuter passes were sold using Eda as a calculation point — a national first. It was finally promoted to a permanent station on 31 March 1987, one day before JR privatisation; assigned operating-kilometres were not set until 10 March 1990.

Notes
Until the early 1970s the signal box had a unique form of switchback: a single dead-end "acceleration line" branching off on the down-grade (Taira/Iwaki) side, used by trains to gather speed before tackling the climb toward Kawamae. The branch joined the platform from its centre, on the Iwaki-side left, and its alignment is still visible.
