Okayama Castle was constructed between 1573 to 1597 by the Ukita Clan. They were on the wrong side of the Battle of Sekigahara and so the castle passed briefly to the Kobayakawa Clan before coming under the control of the Ikeda Clan who held it until the abolition of the domains in 1869.
The castle's nickname was Crow Castle because of its black exterior. The famous Himeji Castle not far away was likewise nicknamed "White Egret Castle".
The Asahi River was utilized as a moat on two sides of the castle.
Some of the roof decorations are gilded, but for its first few years all the roof tiles were gilded earning it the nickname Golden Crow Castle.
