Answer by George Sawyer:
I lived in Japan from 1984 to 1987. At that time foreigners were relatively rare, even in Tokyo. One day I was taking someone sightseeing at Asakusa temple. An older Japanese man, in his 70s? came up to me, he was drunk (and had an open can of sake in his hand). He told me that after the war he thought he would be a slave, they had lost the war. But the Americans rebuilt Japan, they couldn’t believe it. He went on like this for a long time.
This was not an isolated experience, when I mentioned this to other foreigners I knew in Japan, they all said, “oh, yes, that happens.”. That wasn’t the only time I had the experience.
There are ultra-nationalists in Japan who hate the US, who hate the victors, who want to emperor restored as the god-head, etc. etc.
