History
Yairo Station opened on 15 January 1965 as an unstaffed passenger halt on the Jōetsu Line, 127.0 km from the line's southern terminus at Takasaki. A station building was completed in July 1968. The station was absorbed into JR East with the privatisation of Japanese National Railways on 1 April 1987. It retains two opposed side platforms serving two tracks, with no footbridge or level crossing connecting them inside the station precincts—passengers transferring sides must use a nearby town-road level crossing on the Mukaimachi side. There is no station building today; only a sheltered waiting area sits on each platform.
