I went to the Star Wars Exhibition that is held at Sogo Yokohama through 11/25~1/5! The Artworks related to Star Wars taht are exhibited were chosen by George Lucas himself. There are items that were actually used in the films exhibited, and in total 150 pieces are on display.
If you are a Star Wars fan, there will be many situations where you will say "Oh this is __ from the ___ Episode!" at this exhibition! I got very into it as well. It takes time to look at every single piece, so I recommend spending around an hour and half there. There are pieces that are bigger than people, so it is very powerful as well. There is so much to enjoy here at the Star Wars Exhibition, so if you are a Star Wars fan definitely give this place a try!
