what makes you think they would be mad that it wasn't their idea first? communism is about forcing equality. Traditional Japanese were never about that, they always had clear social hierarchies, and caste systems. They'd hate an ideology (Communism) that would try to overthrow that caste system. Imperial Japan banned communism and threw communists in to prisons, and it was actually America that got rid of that law that banned communists so who is actually more pro communist?
But fundamentally, communism/socialism/fascism are collectivist ideas.
Ignoring the likely propagandistic leanings of the text, they might just have been mad that it wasn't their idea first.
