When I lived there I had no problems with the Japanese. The racism in high school was that every group had problems with those outside of their group. Very insular. And that wasn’t just the Asians. It was the Pacific Islanders too.
I once had an opportunity to take a job in Hawaii (actually, Oahu) but declined after I was warned by a friend, whose mother was native Hawaiian, that my two fair-haired high school age sons would have a very hard time being accepted. Paradise isn't worth that kind of grief.
