Yes, I'm an American studying a koryu budo here in America. I belong to the Seitokai lineage of Muso Jikiden Eishin Ryu. I acknowledge Ikeda Takashi as my soke, and shortly Fukui Masato who shall be suceeding him. My certificates are signed by the soke. A kyudan hansi travels once a year from Japan to proxy exams on behalf of soke. At a certain point, I'll be expected to travel to Japan. We have absolutely no connection to ZNKR and do not "do" Seitei. We are, however, affiliated with the ZNIR, but Toho are not part of our ryu or its rank examinations.
The point of my previous posts in this thread was to comment on two issues: 1) if you study a traditional Japanese martial art, then don't be shocked if you regularly hear and are required to learn Japanese terminology; and 2) simply barking Japanese terms/phrases and performing apparently Japanese "mannerisms" without understanding their context/meaning (or even really trying to understand) is clearly absurd and insulting.
Americans fetishizing a certain aspect of a culture they are not part of is ridiculous and deserves to be mocked. However, learning about the culture and respecting it and trying to participate in...while knowing all along that you're non-Japanese and will always be so, is the point.
