Osaka Castle Main Tower (Osaka Castle Museum)

Natasha...
"You can buy and use it at any time, and the price is much cheaper than on-site. You can see the panoramic view of Osaka from the castle tower and learn about the history and culture. It is worth visiting. It is recommended to arrive at 8 o'clock in the morning. The environment is quiet and beautiful for taking pictures, and you can also avoid the large number of tour groups."
