The Osaka Castle You See Isn't Hideyoshi's

Osaka Castle is tied to one name: Toyotomi Hideyoshi. But not one stone wall you can see there was built by him. His castle is still there, buried under the Tokugawa rebuild, and in one spot it's only about a meter under your feet.

Some points in the video are one person's view, and we say whose: the fill-depth figures, the "leveling" reading and the moat-soil guess come from a column writer at the Osaka Castle Museum. The long north–south town plan is historian Uchida Kusuo's theory. The late date of the name "Taikō Gesui" is researcher Yamano Hisao's view. "First flatland castle with high stone walls" is the Osaka Museum of History's description.
