Peasants, Rebels and Outcasts: the Underside of Modern Japan, while covering Japan from the Meiji Restoration to defeat in 1945, has some good stuff about resistance during World War II. It's a popular book in Pacific and Asian Studies, so check out your local campus used bookstore for a copy. Japan at War: an Oral History covers pretty much everything about Japan at war, including recollections by Koreans recruited as slave labour, and sex trade workers.
I also searched Amazon using the keyword kempeitai; there are probably some books connected with that subject that talk about resistance in Japan during the war (although I must say that the word "kempeitai" is almost unknown to contemporary Japanese). No more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
