The line is not electrified, and services on the line are operated by KiHa 40 series diesel multiple unit (DMU) trains.


The line first opened on 9 November 1913 as the Funakawa Light Railway (船川軽便線 Funakawa Keiben?) from Oiwake to Futada.[1] This was extended to Wakimoto on 8 November 1914, to Hadachi on 1 December 1915, and to Funakawa (present-day Oga Station) on 16 December 1916.[1] On 2 September 1922, the line was renamed the Funakawa Line (船川線 Funakawa-sen?).[1]

A freight-only branch from Funakawa to Funakawaminato was opened on 10 June 1937.[1]

On 1 April 1968, the line was renamed the Oga Line, coinciding with the renaming of Funakawa Station to Oga Station.[1]

With the privatization of Japanese National Railways (JNR) on 1 April 1987, the line came under the control of JR East.[1]

Future developments[edit]

From spring 2017, a new EV-E801 series battery electric multiple unit train will be introduced on Oga Line services from Akita. A special recharging facility will be built at Oga Station.[2]
