Around Osaka Castle
A 105.6-hectare park, a rebuilt keep and a boat on the moat
Osaka Castle Park covers 105.6 hectares of moats, stone walls and plum trees, and the keep at its centre was rebuilt in 1931 as a museum of the Toyotomi era. Most of what's here is spread across the park, so plan on walking more than you expect. It's a day-trip district rather than a place with much to do after dark.
Osaka Castle has 12 places on the Roam Osaka map: 3 shrines and temples, 3 parks and gardens, 2 landmarks, 2 museums, 1 shop and 1 bar. Read the Osaka Castle guide.
