History
Yasuoka opened on 22 April 1914 as a station on the Chōshū Railway, a privately operated line in western Yamaguchi Prefecture serving what is now the city of Shimonoseki. The line was nationalised in 1925 and became part of the Kogushi Line, which was renamed the San'in Main Line in 1933 — making Yasuoka the second-to-last station from the line's terminus, 668.2 kilometres west of Kyoto. The 1 April 1987 break-up of Japanese National Railways placed the station under JR West. The layout is two ground-level opposed side platforms linked to the station building by a footbridge, with no permanent staff on site.
