Built on the site of the former temple of the troublesome warrior monks, the Ikko Ikki, Toyotomi Hideyoshi built a truly lavish & seemingly impregnable castle that surpassed all others. The Tokugawa clan reduced it to rubble in 1615 & five years later had succeeded in removing almost every trace of Hideyoshi's efforts & replaced it with an even mightier fortress.
This truly is a spectacular castle to visit. Initially, the fact that the main tower was a concrete reconstruction lowered its estimation in my eyes but the sheer scale is breathtaking. Also, Osaka castle is still in possession of nine buildings that date from the Edo period. Those nine buildings & a well have been designated Important Cultural Properties.
