With a history of over 600 years and counting, Osaka castle is one of the oldest fortifications in Japan. First established as a fort by Akamatsu Norimura (Ensin) in 1333, it would be rebuilt as a permanent fortification known as Himeyama Castle, beginning in 1346 under the supervision of Akamatsu Sadanori. Upon its completion it would take the name of Himeji, in Harima Province, due to changing politics. It has seen several significant figures in Japanese history, each making their residence in this keep. Hashiba Hideyoshi, younger brother of Toyotomi Hideyoshi, is one such figure. In its history, the castle and much of the domain would exchange private hands many times before being given to the government in an effort to maintain and preserve it's historical presence. Two major restoration efforts would be undertaken, one in 1934-1950 (Showa Era Restoration), and most recently in 2009-2015 (Helsei Era Restoration). Himeji would also have the honor of not only being named a World Cultural Heritage Site but also Japan's First such site.
