I understand your feelings... and that was my first instinct... I have had dealings with people of different cultures, and in the past I did have good success by attempting to "fit" in... but again that was a different group of cultures.
I have a basic understanding of the Japanese culture, and the "pompus" attitude some perceive.. My son is in Japan at the moment.. and I am sure he is getting a crash course on the Japanese culture.. as a Marine at Fuji, I am sure he has received some of that same stereotypical attitudes.. and being Navajo Indian, his appearence will throw them off...
I hope you are able to resolve this current situation, and in a way you can gain respect... for them.. I know respect and honor are important.. at least for themselves..
