The Osaka Museum of History is very close to Osaka City. You can consider visiting it together. It is on the 7th to 10th floors of a tall building. It can take a panoramic view of Osaka City in the corridor between floors. It has cultural relics, physical models, and can also experience archaeology personally. If you have time, you can take time to see it. By the way, next to it is the police headquarters of Osaka Prefecture.
