History
Osaka Business Park Station opened on 11 December 1996 as the line previously called the Tsurumi-ryokuchi Line was extended from Shinsaibashi to Kyōbashi and renamed the Nagahori Tsurumi-ryokuchi Line. The platform sits 32.2 metres below ground, making it the deepest station in the Osaka subway network; original prefabricated platforms built one basement level higher had to be abandoned because the Neyagawa and Daini-Neyagawa rivers run nearby, and the city required the platforms to lie at least 10 metres below the riverbeds. The 107-metre tunnel section between the access shafts was driven by the world's first triple-circle multi-face shield machine. Platform-edge doors entered service in 2010, and the station passed from the Osaka Municipal Transportation Bureau to Osaka Metro at privatisation on 1 April 2018.

Notes
Although it has no transfer connection today, a 1990 underground level of the Matsushita IMP building directly above the station holds an unused "phantom platform" originally laid out for a planned future link.
