Near Osaka City, after visiting Osaka City Park, you can walk to the History Museum, next to the NHK Building. The Osaka Tour Ticket is free to visit and take the elevator up to 10 floors. Then you can visit from the 10th floor down one by one. On the 10th floor, you can pick up a piece of paper freely, cut it along the marking line with scissors in the middle, fold it, and fold it into a pamphlet. Each page has a number. Then you can take the pamphlet and turn it to each layer to seal it. Standing at the window of the History Museum, you can see Osaka City, the moat, and the scenery is very beautiful.
