Osaka Castle

Construction on Osaka Castle (Osakajo) started in 1583 on the former site of the Ishiyama Honganji Temple, which had been destroyed by Oda Nobunaga thirteen years earlier. Toyotomi Hideyoshi intended the castle to become the center of a new, unified Japan under Toyotomi rule.

However, a few years after Hideyoshi's death in 1615, Tokugawa troops attacked and destroyed the castle and terminated the Toyotomi lineage. Osaka Castle was rebuilt by Tokugawa Hidetada in the 1620s, but its main castle tower was struck by lightening in 1665 and burnt down.

The current reconstructed donjon was actually first built in 1931.
