Oshi Castle Ruins & Gyoda City Museum
The “floating castle” that withstood a siege by water.
Built in the 15th century, Oshi Castle is famous for resisting Ishida Mitsunari’s flood attack during Toyotomi Hideyoshi’s campaign. Its story inspired the novel and film The Floating Castle. The reconstructed three-storey turret and local museum introduce the castle’s past and Gyoda’s tabi-sock craftsmanship.
