Well, like I said I only watched the movie once, and he pretty much says everything you just said, only I remember him ending it with something along the lines of "because I'm a Jew".   Somebody tell me if I need to watch it again....

I think that's not exactly what Zorn says, or at least
what happened. According to Zorn's own words, he
didn't feel accepted in Japanese society, despite
learning the language, living there 6 months a year
for several years and playing with everyone. I could
be wrong, but I think Jewishness wasn't involved in
his disappointment towards Japan.
