Osaka Castle 大阪城
The keep is from 1931, paid for by the city's residents: the third after the Toyotomi and Tokugawa keeps.
The keep you see today is the third generation, after those of the Toyotomi and the Tokugawa: it was rebuilt in 1931 with donations from the citizens of Osaka, and in 1997 it became a national Registered Tangible Cultural Property.
