You hear the same thing from Nihonophiles, that Japan is this wonderful country full of wonderful people who are never rude and produce perfectly clean cities, amazing convenience stores, and technology generations ahead of us. The funny thing is, all that is true, but there's an underbelly which is kept well hidden, and that is the continuous xenophobia. As long as non-Japanese are temporary visitors, they are treated like royalty, but as soon as they start wanting to BECOME part of Japan, living becomes increasingly difficult to impossible. And there's the dirty little non-secret, it wasn't all that long ago that the Japanese were horrible, disgusting, genocidal fascists who made the Nazis look like flower children, and it wouldn't take more than a generation and a sufficient world situation to turn them back into the same again. Confucianism doesn't have an answer for any of that; Judaism and Christianity do, which is why they are so rarely practiced in Japan in spite of the plethora of mission work over the last 170 years.
