Eh that's not really true in the case of Japan though, they are generally pretty keen to push the message that they were the real victims of the war, with the bomb and all that, and denying all of the many atrocities their forces committed in the territories they occupied. Also, I'm not sure Austria-Hungary belongs on that list, as far as I'm aware they didn't commit any more egregious war crimes than any other WWI combatant, sure a lot of them ended up joining the Nazis 30 years later, but the empire is hardly to blame for that as it had long been broken up by then.
