To me tweed is a fabric with entirely British connotations - a kind of regional thing. It looks 'off' on Asians. As one, I won't wear it. In some instances it looks fine on younger Asian guys; but youth can get away with a lot.

I'm not sure about the Japanese guys that adopt this. Some few look good, most are costumey.
I don't agree with this at all. Your vision of culture and ethnicity really doesn't take into account the multiculturality of many industrialised countries, and how style can be adopted by anyone, so long as it complements their complexion, build, etc. Perhaps I'm over-interpreting this, but by this rationale you might as well say that ALL non-Europeans shouldn't wear suits, since after all, the suit is a Western European creation.
On a personal level, I'm of Chinese descent, born in the UK and wear tweed, windowpane fabrics, prince of wales... Where would that put me? Costumey? Rdiculous? I' don't think so. Worsted fabrics don't look any less costumey than tweed - it just depends on your frame of reference.
