Meh, I don't think anti-Chinese hate among Japanese is very pronounced. It flares up when some CCP aggression hits the news. Japanese hate the country China, but on an individual level many Chinese work in Japan and they get along just fine and even become friends. It's totally normal and not an exception.

Now if you're talking about living next door to a Chinese family, yeah a lot of people would avoid that if they have a choice - simply because foreigners are loud and obnoxious. Japanese would rather live among Japanese.

Can't speak to attitudes of people in China. They get a lot of anti-Japan government propaganda, and some of that bad blood is justified.
