History
Ōami Station is a junction station in Ōamishirasato, Chiba Prefecture, operated by JR East. It opened on 20 January 1896 as the terminus of the Bōsō Railway, which extended onward to Ichinomiya in 1897; the connecting Tōgane Line followed on 30 June 1900. The Bōsō Railway was nationalised on 1 September 1907 and absorbed into the Japanese Government Railways, later Japanese National Railways. Freight was discontinued on 1 July 1971, and on 27 May 1972 the station building was shifted to a new site to eliminate the previous switchback layout. The station passed to JR East at privatisation on 1 April 1987.

Notes
The 1972 rebuild relocated the entire station to remove the switchback that had previously forced through trains on the Sotobō Line to reverse direction at Ōami.
