Osaka castle is very beautiful. I was impressed by its size and really liked how this castle/park was surrounded by water. As soon as you enter the park, you will feel like you came to ancient Japan because there are many Japanese people dressed up in traditional Japanese outfits. There were also many cultural activities held inside the park. I didn’t participate in any, but watching many Japanese participating in those activities looked interesting.
The reason why I’m only giving 4 stars is because the inside of the castle building wasn’t very impressive. Inside of the castle was like Japanese historic museum. As a tourist who do not know much about Japanese history, it wasn’t entertaining. Since the castle is pretty tall, you can get a pretty nice view of the city from the highest floor of the castle. But overall, I don’t think it’s worth the ticket price to go inside the castle. Especially if you don’t know Japanese history. However, I really recommend visiting Osaka Castle. The castle is beautiful and the park is great place to spend time.
