Osaka Castle

Osaka Castle is widely known as an emblem of the power and fortune of Hideyoshi Toyotomi.
In 1583, Hideyoshi began construction at the former site of Honganji Temple and completed the magnificent castle, which was reputed as being unparalleled in the country.
Hideyoshi, having employed the castle as his stronghold, succeeded in quelling the wars which had continued for more than one century, thereby unifying the entire nation. 
After Hideyoshi’s death, Ieyasu Tokugawa, who worked for Hideyoshi as his chief retainer, was appointed to the Shogun and he established the shogunate (government) in Edo (Tokyo). In 1615, Ieyasu ruined the Toyotomi family and destroyed Osaka Castle (in the Summer War of Osaka). 
Thereafter, the Tokugawa shogunate reconstructed Osaka Castle. It held the castle under its direct control until 1868, when the Tokugawa shogunate lost power and the castle fell. 
In 1931, the Main Tower of the Castle was reconstructed in the center of Osaka Castle, which was used as a military base, with funds raised by the citizens. 
The present-day Main Tower is the third generation. It follows the Main Tower from the Toyotomi period, which was destroyed by fire during the Summer War, and the tower from the Tokugawa period, which was struck by lightning and was burned down. 
Since its construction, Osaka Castle repeatedly featured as the battleground of the major wars in Japanese history.
Osaka Castle has been popular with both domestic and overseas tourists as a historic site which has been handed down through the above-mentioned historical dramas to today.
