Nothing surprising here. Japan has been and is a racist society.
" is a racist society."
Whatever racism still remains exists in old fogeys over 60...The Japanese are no more racist per capita than the US , England or any other Western country .
No surprise indeed. Japanese racism is a well known part of their national character. I'd be more interested (and even impressed) if the UN investigated the continuing Arab slave trade, treatment of Filipino and other guest workers in the Arab Gulf countries, and how Islam justifies (along with mass murder of innocents, pedofilia, second class treatment of "dhimmis", etc.) all of this. Not holding my breath on that one.
They are even deeply rascist against themselves. They go to great extremes to look different. Don't get me wrong I have a daughter who lives there and have been there several times and they are wonderful people. I think we should be more protective of our lifestyle.
