Departure data for this station is not available on this site.

Ōsakakō Station opened on 11 December 1961 with the inaugural section of the Osaka Municipal Subway Line 4 (today's Chūō Line) between Ōsakakō and Bentenchō, serving as the line's western terminus. On 18 December 1997 it became the through-running boundary with the OTS Techno-port Line to Cosmosquare. The OTS rail business was transferred to the municipal subway on 1 July 2005, making Ōsakakō an intermediate station on a unified line. The station passed to Osaka Metro on 1 April 2018 with the privatisation reform. A station renovation themed "sea" finished on 31 March 2025, and a new west-end viewing deck opened on 11 April 2025.

Before the subway arrived, the Chikkō district was served by three Osaka City Tram stops at three separate points: Ōsakakō, the terminus in front of the Osaka Customs House by the Chikkō pier; Sanjō-dōri Yonchōme, at the Chikkō intersection where the subway station now stands; and Tempōzan-sanbashi, at the Tempōzan intersection. All three were suspended on 1 August 1960 for subway construction and later abolished.
