I stand by what I stated. Japanese are one the most racist people on the planet, it does not mean ALL of them are. I have many Japanese friends who are open minded and also hate Japan the way it is today. You have to understand Japan is a very collective nation. Unlike western countries, where individual ideas and freedoms are valued, in Japan, group mentality supercedes everything else. You would not understand unless you have lived in Japan.
Some of my best Japanese friends are frank with me when they are alone, telling me their thoughts and contempt towards certain aspects of Japanese society, or the company they work for, or school they attend. But when back in the group, they become "social robots" obeying everything that's acceptable as norm, often acting against their own will for the betterment of the group. - that is one reason they were so successful before WWII as a small country against vastly outnumbered other Asian nations such as Chinese, and why they are so successful economically during post-war recovery. But the same collective group mentality also attributes to their discrimination against foreigners because multiculturalism cannot possibly thrive in such a comformitive society.
Don't get me wrong, I know many warm hearted Japanese who invited me ( as a stranger, foreigner) to their homes, parties. Far more welcoming than Canadians in fact. But again, they are acting as individuals. As soon as they are back in the group settings - company, school, community events, you are suddenly outsider. Not to mention they have the most strict immigration laws, and foreigners must change the last name to Japanese one to apply for citizenship, and non-citizens can't own land - even if you are married to a Japanese. Every aspect of Japanese society speaks "we are a superior, special race"
That's why so few westerners can truly understand Japanese racism as they try to superimpose white - black racism over Japanese - filipino, korean, chinese racism, it's like comparing apples and oranges. Frankly I don't think Westerners care about discrimination Japanese against other Asians in Japan, as it does not really affect them.
