Welcome, Fizban. At the risk of trying to teach grandmother to suck eggs: have you checked these sources?http://books.google.com.au/books/about/ ... edir_esc=y
I have not yet read this myself, but it concerns Peter Russo, an Australian who was teaching in Japan for several years up to mid 1941. This book is about him, not by him. I read something he wrote ca 1947 about this period, the assassinations, the Black Dragon Society, communism among students, the political police snatching students from his classes (and never hearing of them again), and the incidence of TB and the methods used to dodge conscription. (This article would not be available to you, and I cannot access it again.)
The other is a book by Sidney Mashbir, "I was an American Spy". (I think that is the title)
A little while back, while searching for "Shina no yoru" on Youtube, I came across a clip from a 1940 Japanese film. Interesting to see how they saw themselves. Send me a Private Message if you want to inquire about this. It is not particularly relevant to the forum.
