The airport is often called Itami Airport (伊丹空港) because most of its land is located in Itami, Hyogo Prefecture. However, the terminal complex is located in Toyonaka, Osaka Prefecture, and the only access from the Itami side is via a long tunnel that passes below the runway and apron.
Despite its "international" designation, the airport's scheduled air traffic is entirely domestic. Kansai International Airport took over Osaka's international traffic in 1994 and competes with Itami for domestic traffic. Itami will also face competition from Kobe Airport when that airport is completed.
Osaka Airport is accessible by the Osaka Monorail, as well as by regular bus service from most transportation hubs in the Kansai region.
