Sapporo Factory is a complex facility including shopping mall. It used be the first beer factory in Japan. After closing this factory, this heritage was redeveloped as a large shopping mall. In this facility, there are shops, restaurants, clinics, a theater, a cinema complex, a hotel and so on.
This time, I found some Mobil Suits of Gundam including a big head. Many people pretending civilians took pictures of these high spec armaments. If you want to investigate Japanese military, it may be a good idea to ask your boss to let you go to Sapporo Factory.
