Completed in 1597 after eight years of construction, Okayama Castle is one of Japan’s top 100 castles. After the keep was destroyed in the war, the castle was rebuilt in 1966. Also known as “U-jo (Crow Castle)” for its crow-like black outer wall, Okayama Castle is a popular counterpart to the white outer walls of Himeji Castle.
