Aohori Station opened on 15 January 1915 as a stop on the Japanese Government Railways Kisarazu Line, in what is today the city of Futtsu, Chiba Prefecture. The line was successively renamed: Hōjō Line in May 1919, Bōsō Line in April 1929, Bōsōnishi Line in April 1933 and finally the Uchibō Line on 15 July 1972. Freight handling ceased on 1 October 1969, the green window (Midori no Madoguchi) closed on 1 April 2006 and the experimental "Kaeru-kun" remote ticket machine was withdrawn on 23 March 2012 — its final operating station. Privatisation on 1 April 1987 transferred Aohori from JNR to JR East. The station is operated as a contracted facility by JR East Station Services.

Before the Pacific War, a military spur line branched from Aohori to the Imperial Japanese Army's Futtsu Proving Ground, hosting the Type 90 240 mm railway gun before that piece was redeployed to Manchuria's Hutou Fortress.
