2. History of Osaka Castle

■ Construction by Toyotomi Hideyoshi (1583 - 1598)

Osaka Castle's construction began in 1583 by Toyotomi Hideyoshi on the site of the former Ishiyama Hongan-ji Temple. This castle was planned as a symbol of Hideyoshi’s power after unifying the nation. It took 15 years to complete, featuring elegant architecture such as black plaster walls and gold-leafed tiger ornaments. After Hideyoshi’s death, the castle continued to serve as the headquarters of the Toyotomi clan, but tensions with the Tokugawa clan gradually increased.

■ Reconstruction by the Tokugawa Clan and the Siege of Osaka (1603 - 1615)

After Hideyoshi’s death, Tokugawa Ieyasu established the Tokugawa shogunate in 1603. Although Osaka Castle remained under the Toyotomi clan’s control after this political shift, it played a crucial role during the Siege of Osaka (Winter Siege of 1614 and Summer Siege of 1615). During the Summer Siege, Tokugawa forces set the castle on fire, causing significant destruction. Toyotomi Hideyori and his family perished in the battle, leading to the fall of the Toyotomi clan.

■ Reconstruction during the Edo Period and Fires (1619 - 1665)

Following the Siege of Osaka, the Tokugawa shogunate began reconstructing Osaka Castle. From 1619, Osaka became a direct territory of the shogunate, with major reconstruction efforts led by the second shogun, Tokugawa Hidetada. This reconstruction continued under Tokugawa Iemitsu but was interrupted in 1665 when the main tower was struck by lightning and burned down. Despite facing several natural disasters over the years, the castle was repeatedly restored.

■ Reconstruction in the Showa Era and the Modern Period (1931 - Present)

In 1931, the main tower of Osaka Castle was rebuilt with reinforced concrete, funded by citizen donations, and repurposed as a history museum.

Today, Osaka Castle Park functions not only as a historical site but also as a beloved park for citizens and tourists.
