Osaka Castle Park
Nationally designated special historical site, Osaka Castle Ruin, and the surrounding area were renovated into an urban park. 13 buildings of important cultural properties including Osaka Castle Main Tower, watchtowers and gates dot the vast 261-acre premises.
There are cafes and little food stalls inside, so you can stroll around, eat, and enjoy the scenery—super chill vibe!
If you have enough time, I totally recommend going in the evening to catch the sunset. The castle looks absolutely stunning with the sunset backdrop!
