When taking in the context that this is a propaganda film made about Japan during World War 2 with the goal of making viewers side with the USA and support their military actions against Japan, this documentary is quite interesting. In the beginning, the narrator mocks the Japanese army by calling them short and tiny men. The film states many completely made up and bonkers "facts" about Japan. The narrator goes into talking about Shintoism and he ends up telling his audience that they want to wipe out everyone who is not Japanese. It's easy to see why there were second thoughts about releasing this film. If you want to see an example of a very harsh propaganda film, then I recommend that you check this out. If you want to learn a bunch of true facts about Japan, then this documentary is not the right one for you. It is quite hard to imagine anyone taking the narrator seriously, even in the 1940s.
