Seen at the Osaka History Museum, the 10th floor is covered with curtains on one side of the exterior wall. On the wall, small films are shown on a row of large screens telling the history of ancient difficult waves. At the end of the film, the curtain automatically rises and the ruins are outside the glass windows. The visual impact really shocked me. My little friends and I were shocked. The museum design in Japan was really beautiful, unforgettable and a wonderful journey.
