During what was to be the last of his three terms, Prime Minister Nakasone also uttered the following quote:
(Nippon wa tan'ichi minzoku dakara, sabetsu wa sonzai shimasen.)
"Japan has only one ethnicity, and thus no discrimination."
Understandably, this statement was not taken very well by those of Korean, Ryukyuan, Latin American, Chinese, Filipino, Ainu, and other heritages who, at that time, consisted some 3,000,000 of Japan's population.
This famous phrase completed the circular logic of discrimination and minorities in Japan; these groups of people were (still are?) not considered minorities because they were not discriminated against.
