History
Aioi Station opened on 10 July 1890 as Naba Station, on the Sanyō Railway's westward extension between Tatsuno and Ari. The line was nationalised in 1906 and the station was redesignated under the new Sanyō Main Line in 1909. The station was renamed Aioi on 1 October 1942 to match the newly chartered Aioi City. The Akō Line opened from here in December 1951, and the Sanyō Shinkansen platforms were added when the Shin-Osaka–Okayama segment opened on 15 March 1972. Hikari trains served the station from opening until 1997, were dropped, then partly restored in October 2001, and JR West took over the station at privatisation in 1987.

Notes
When alphabetised, Aioi ranks first among all Japanese train stations — and an obscure dead-end track at the Shinkansen platform was originally laid for a never-realised "night Shinkansen" service that would have required single-track operation.
