There 100% is for Asians and black people.

Among black people, there’s a lot of “colorism” where people are/aren’t judged to be black “enough”. Lots of lighter skinned black people getting discriminated against, for instance. Or black people who are too dark getting excluded by lighter skinned black people. It’s not super common, but happens often enough that mixed-race people often feel excluded because they’re too light to fit in with black people but too dark to fit in with white people.

With Asians, there’s a lot of racism too. For instance, a lot of the lighter skinned Asians (Koreans, for instance,) have historically been horribly racist against darker skinned Asians, like Vietnamese. Korea also has a huge emphasis on looks, to the point that it can be difficult for anyone who doesn’t conform to traditional beauty standards. And yes, that means foreign Asians are affected.

And Japan is weirdly conservative in a lot of ways, and is also the most homogenous population in the world; It’s something like 98% of the population is native Japanese. So any foreigners will automatically stand out. Tourists are tolerated, but anyone trying to live/work in Japan will struggle to be taken seriously. For instance, a Japanese employer will almost always prefer a native Japanese applicant over a more qualified foreign applicant. As a foreigner, your main methods of getting employment are “transfer into Japan from a branch in another country,” “start your own business,” and “do a job traditionally reserved for foreigners.” For the first example, think of something like Toyota transferring an employee in from America. The employee is already established within the company, so they didn’t need to deal with the regular application process (which would have excluded them from getting hired if they had been applying from within Japan.) And for the third option, that’s typically jobs like English teachers and novelty restaurant hosts.
