The racism in Japan isn’t outward, they keep it to themselves. You wouldn’t even notice it if you went there as a tourist, since they stay polite. The “no gaijin allowed” places are rare unless you want to visit a certain type of establishment 😉 Japan has systemic racism against ethnic Chinese citizens, but the average Japanese person isn’t really racist to Chinese people and if they are it’s from ignorance rather than hatred. Japan is one of the top foreign destinations for tourists from China. It wouldn’t be if Chinese people weren’t welcome.

You’d have a tougher time in South Korea. Where they actually say racist shit to your face.
