History
Ōsakajōkōen Station opened on 1 October 1983 as a Japanese National Railways stop between Morinomiya and Kyobashi on the Osaka Loop Line, timed for the 400th anniversary of Osaka Castle's construction and the accompanying Osaka Castle Exposition. Its black-and-white walls and green-coloured roofs were designed to echo the silhouette and patinated copper of the adjacent castle. With JNR privatisation in 1987 it passed to JR West. ICOCA service began in November 2003, and a Loop Line traffic-management system was installed in October 2009. Station numbering JR-O07 was introduced in March 2018. The departure jingle "Horagai" (conch trumpet), referencing the Siege of Osaka, was adopted in March 2015.

Notes
Ōsakajōkōen is the only at-grade station on the Osaka Loop Line; the area was once the Osaka Arsenal, and the wartime Imperial Army refused permission to elevate the tracks because doing so would risk exposing classified military structures to public view.
