There are some definite oddities in the German-Japan alliance in the second world war:
-Both nations were racist nationalists who thought they were naturally superior. Both allied with a nation who very much was NOT their “superior” race
-Their alliance was almost never relevant. Did they ever meaningfully work together? (Arguably Japan got by FAR the better of the deal, as Hitler declared war on the USA, pulling an awful lot of focus, but Japan never invaded the Soviet East, which would arguably have pulled a ton of attention away from the German invasion in the West.)
But of course at the same time, both nations achieved, for a time, stunningly amazing military victories.
So what did the average German think when he heard about, say, the fall of Singapore? What did the average Japanese civilian think when he heard about the fall of France?
Did German or Japanese civilians ever visit each other as tourists? Would they have been welcomed? What was the general attitude towards the ally from the other side of the world?
