Overview

Osaka Castle is a reconstruction of a 16th-century fortress, originally built by Toyotomi Hideyoshi to unify Japan. The current main keep is a modern concrete building housing an extensive museum documenting the castle's history and the Sengoku period. The structure sits on a high stone foundation surrounded by a massive double-moat system and secondary stone walls. The museum exhibits feature gold-leaf folding screens, historical weapons, and dioramas depicting the 1615 Siege of Osaka. The castle grounds encompass 2 square kilometers, including expansive lawns and a significant plum orchard. The surrounding park serves as a green buffer in the center of the Chuo Ward commercial district. Architectural elements include steep, decorative gables and golden tiger motifs on the black-and-gold exterior.
