Osaka Castle was built after Toyotomi Hideyoshi was unified in Japan in 1583. The entire project took 15 years and used 130,000 people, which is 4 to 5 times the size. Together with Nagoya Castle and Kumamoto Castle, it is known as Japan's three famous cities. It was designated as an important cultural heritage of Japan in 1997 and is still a symbol of Osaka.
In addition to the Osaka Castle, the entire ruins are planned to be Osaka Castle Park, Nishino Maru Garden, Osaka Castle Concert Hall, Osaka Castle Auditorium, Osaka Castle Bow Stadium, Shudokan, and Osaka International Peace Center.
