Osaka Castle
Osaka CastleOsaka Castle is the symbol of Osaka residents. The castle was originally built by then Toyotomi Government but after the battles for the switch of the Japan's ruler from Toyotomi Family to Tokugawa Family, the original structures were mostly buried and during the early Edo Period under Tokugawa Shogunate Government, the castle was rebuilt on the original site. Currently 13 structures including turrets, gates, and storehouses keep the original construction of early Edo Period but the castle tower, or the donjon, was rebulit after the World War II. It is made of ferro-concrete. Now it is the 5 layer-8 storied building and the inside serves as the museum. It displays the history and the life during the reign of the founder Toyotomi Hideyoshi with armors. The display includes the reprica of golden walled tea room and the minuture model of Osaka Castle, etc. Near some of the gates, the visitors will find huge stones used as part of the walls. The biggest one weighs 130 tons. Some of those stones were shipped from the islands in Seto Inland Sea. You will find it puzzling how those were delivered from the quarries to the castle in the old days.
