History of Osaka Castle Park
Toyotomi Hideyoshi and the Birth of Osaka Castle
The history of Osaka Castle begins with Toyotomi Hideyoshi’s start of construction in 1583 (Tensho 11) on the site of the former Ishiyama Hongaiji temple. Inheriting Oda Nobunaga’s vision, a magnificent castle complex was constructed as the headquarters for the unification of Japan, incorporating the highest technology of the time. Hideyoshi built a splendid main keep covered in gold leaf, and Osaka Castle stood as a symbol of power.
Reconstruction in the Edo Period
Osaka Castle from the Toyotomi period was destroyed in the Osaka Summer Campaign of 1615. Subsequently, the Tokugawa shogunate began large-scale reconstruction work from the 1620s, completely burying the castle from the Toyotomi period and building a new castle on top. Most of the stone walls and moats visible today date from this Tokugawa period.
Osaka Castle Park in Modern Times
After the Meiji Restoration, Osaka Castle came under military management, and many military facilities were constructed. In 1931 (Showa 6), the main keep was restored through public donations, and after World War II in 1948, Osaka Castle Park was developed. Since then, it has evolved into a place beloved by citizens and tourists as a historic park.
The Charm of Osaka Castle’s Main Keep
Characteristics of the Main Keep
The current Osaka Castle Main Keep is the third main keep, reconstructed in 1931. Standing approximately 55 meters tall with 5 stories and 8 floors of reinforced concrete construction, its exterior reproduces the appearance from the Toyotomi period. With white walls and gold decorative shachihoko (mythical roof ornaments) and tigers, the magnificent exterior stands out distinctly even from a distance.
