Osaka Castle is a Japanese castle in Chuoku Osaka Japana The castle is one of Japan’s most famous landmarks and it played a major role in the unification of Japan during the sixteenth century.
The main tower of Osaka Castle is situated on a plot of land roughly one square kilometre. It is built on two raised platforms of landfill supported by sheer walls of cut rock, using a technique called burdock piling, each overlooking a moat. The central castle building is five stories on the outside and eight stories on the inside, and built atop a tall stone foundation to protect its occupants from attackers.
In 1583 Toyotomi Hideyoshi commenced construction on the site of the Ikkō-ikki temple of Ishiyama Hongan-ji. The basic plan was modeled after Azuchi Castle, the headquarters of Oda Nobunaga. Hideyoshi wanted to build a castle that mirrored Nobunaga's, but surpassed it in every way: the plan featured a five-story main tower, with three extra stories underground, and gold leaf on the sides of the tower to impress visitors. In 1585 the Inner donjon was completed. Hideyoshi continued to extend and expand the castle, making it more and more formidable to attackers. In 1597 construction was completed and Hideyoshi died the year after. Osaka Castle passed to his son, Toyotomi Hideyori.
During the summer Osaka campaign in 1615 general Sanada fend off the Tokugawa force many times as the picture above says. Tokugawa clan outnumbered more than twice . Osaka Castle fell to the Tokugawa clan, the Toyotomi clan perished, Hideyori and Yodo-dono committed seppuku and the castle buildings burned to the ground.
