Yep, i am intereste in the subject.
Why do I get the impression you know I will discover some things are not as they appear to be.
Rhetorical, I know.
Well, I'm going to give you the benefit of the doubt and assume your question is sincere an you're not a flame’er. So, I'll give you a sincere answer.
I'm somewhat of a history buff and enjoy reading about WWII and thereby I suppose coming across articles about Japanese culture, past and present, are natural extensions. Just a few things to consider to get you started; research the word “Gaijin”, not the sanitized version, the original intent. Do a search on Japanese-Koreans; those descended from Koreans brought to Japan during WWII as forced labors, sex slaves for the troops, etc. Check out how these people are treated still, ponder why they are still not given Japanese citizenship. Research the art of subtlety used by Japanese, drives U.S. business people nuts, I think psychiatrists refer to as passive resistance, or some such. Anyway, the obvious is not the obvious with the Japanese. If you want, we can have a follow up after you do some reading on this and I be happy to play...
