Osaka-jo: stone walls and a reconstructed keep above Osaka

Osaka-jo, the rebuilt castle rising over central Osaka, combines sixteenth-century stone fortifications with a twentieth-century main tower and a broad park around its moats.

Osaka-jo, better known in English as Osaka Castle, is a historic fortress in central Osaka whose massive stone walls and reconstructed main tower rise above a wide expanse of moats and parkland. The castle traces its origins to Toyotomi Hideyoshi in 1583, yet the main tower visitors see is a ferroconcrete reconstruction completed in 1931 that anchors the surrounding grounds.
