You have seen WS marry asian women en mass. You question it. Why is Japan the only non European Nazi axis power? They were honorary Aryans. You would of course need to read Mien Kampf to see how Hitler praised them. This would go way deep, but the gist is that Light Skinned Asians feel accepted by and of equal footing with the regarded Nordic historically. It manifests through the generations that follow. The pinky swore during WW2

Between China and Germany...and Japan...you will find no other nations as deep in the genetic research/IQ study etc on the planet. It's eery brehs.
