It is impressive~
We didn’t have the time to go through and read each exhibit. I also don’t know much about Japan’s history, so I couldn’t fully appreciate it. (｡•́︿•̀｡) Still, the exhibits were pretty cool.
You can stamp your brochure/notebook/any paper as a souvenir. Too bad, I left my journal at the hotel.
Keep in mind that on some floors, picture taking is not allowed.
If you plan to visit Osaka Castle, use the elevator and go straight to the top floor/ observation deck. After enjoying the view of the city, use the stairs to descend to each floor. This is a less taxing compared to climbing up the stairs to each floor. (elevator only stops on the first and 8th floors)
We chose to climb up the stairs to each floor; by the time we reached the 8th floor, I was too tired to appreciate the view. (╥﹏╥)
