What did the government propaganda and war films portray the Japanese as during World War 2?

Ideologies and philosophies, ways of life, and cultures clash. War is no longer only between soldiers on a battlefield but between nations and their ideas. And in order to make a whole nation of people support the war with mind and spirit, there needs to be influence. That influence is Propaganda.
Much of the social warfare between the United States and Japan involved instilling within their people both a strong nationalistic pride for their own country as well as an incendiary hatred for the other. This was done with the help of the media, newspapers, books, radio, and film.
