So, I just found out that this exists: /r/TokyoTrials
I really have no idea why there could be still so much clamor about random war facts in the WWII right now (who's questioning for instance Stalin's management of famines or the two freaking atomic bombs casually dropped on Japan?), but from time to time I see this question arising again. Is it some kind of revisionist mumbojumbo or is there really some doubt about what it is usually portrayed as the Japanese brutal behavior during the war?
And also: why the hell it matters so much what Japan did right now? Sometimes it just blow up again like when they visit the WWII memorial shrine or when they talk about Chinese prostitutes. You don't hear that about other countries, but it may just be that Reddit loves to talk about Japan for whatever reason.
But this might break the 20 year rule, so yeah.
This (old) thread should help:
