The museum was separated into inside and outside part. Inside, you will go through a dark tunnel, and then reach at the exhibition space, which was used as a part of the factory. There will always be staffs helping you; sometimes they will give a brief introduction about the art pieces.
At the final exhibition room, there might be an Japanese old lady. I think she can introduce the history for tourist, however, it's a shame that I don't understand Japanese.
When you go outside, just follow the sign. You can see some remains everywhere. I think a good museum is the combination of art and history, and this museum is definitely the good one.
