The only reason I even found out about Unit 731 was because there was some contentious discussion going on on a reddit forum I frequent about some individuals getting the traditional Japanese Rising Sun tattoo, and then one thing led to another while reading wiki, and here I was finding out about Unit 731. I never even heard about the Japanese side of the war in school besides maybe a bit about Pearl Harbor myself, btw.I haven't heard much from the Japanese side either, usually history classes spend a lot more time with the Eastern Front. Even a American war book that has chapters of each war has less about the Western front. Not counting movies or games almost always focus on Eastern front.
The documentary link I had posted doesn't go too much into the actual gruesomeness of the experiments that had been performed, but, if you guys want to find out more there's plenty of much more graphic documentaries on youtube.
