The construction of Osaka Castle (大阪城, Ōsakajō) started in 1583 on the former site of the Ishiyama Honganji Temple, which had been destroyed by Oda Nobunaga thirteen years earlier. Toyotomi Hideyoshi intended the castle to become the center of a new, unified Japan under Toyotomi rule. It was the largest castle at the time.

Located around Namba Station, Minami (南, "South") is one of Osaka's two major city centers. It is the city's most famous entertainment district and offers abundant dining and shopping choices. The district is easily accessible as it is served by three train companies as well as three subway lines and a highway bus terminal. The other major city center is Kita (北, "North") which is located around Osaka and Umeda Stations.
