All of the Japanese people I have met have been very nice.
My study partner in my German language class was a Japanese national. I never got any sense that she was condecending towards me or other Americans.
Japan was, as of the mid-90s, the single biggest donor nation in the world. They donated more money than the USA even though the USA's GNP was, what, 5 times the Japanese GNP.
While I obviously don't know him, Mitsu seems like a genuinely nice fellow.
Yes, there is ingrained racisim in the Japanese national character, but Hangtime blows it way, way out of proportion. He also makes the mistake of assigning it to all Japanese people. Many, perhaps the majority, Japanese people are not racist. To so blackly condemn an entire people is abhorant and blatantly more racist than anything post-war Japan has done.
