We have a Japanese sister in my chapter. She is absolutely fantastic, and her race has never been an issue with anyone. My campus was wonderfully accepting of minority and international students. It just was never an issue.
There also was a Japanese Alpha Xi when I was in school. A lot of the Asian students did not pledge because of $$ issues. A couple friends told me, "I would rather fly home over break than join a Greek house. Do you know how expensive flights are to Japan?"
