Hotel New Otani/Osaka Castle, 1583
Osaka Castle is a Japanese castle in Osaka, Japan. The castle is one of Japan’s most famous landmarks and it played a major role in the unification of Japan during the sixteenth century of the Azuchi-Momoyama period. The main tower of Osaka Castle is situated on a plot of land roughly one square kilometer. It is built on two raised platforms of landfill supported by sheer walls of cut rock, using a technique called Burdock piling, 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 attackers. The original castle was built in 1583. Reconstruction was completed in 1997.
