Osaka Castle (Ōsaka-jō) is a castle in Chuo-ku, Osaka, Japan. Originally called Ozakajo, it is one of Japan's most famous castles, and played a major role in the unification of Japan during the sixteenth century.
The castle is situated on a plot of land roughly one kilometer square. It is built on two raised platforms of landfill supported by sheer walls of cut rock, each overlooking a moat. The central castle building is five stories on the outside and eight stories on the inside, and built atop a tall stone foundation to protect its occupants from sword-bearing attackers.
