Osaka Castle is a must-visit check-in spot.

Anyone visiting Osaka should not miss this place. The famous Osaka Castle is an ancient landmark of the city. I must say the area is very spacious, perfect for a leisurely walk. Taking photos here is a lot of fun, even though there are quite a few people, it's not overly crowded. The weather was nice and not too hot when we visited, and there are many photo spots. We didn't go inside the castle, just explored the outside area. It's definitely a popular spot that you must visit again.
