Asian countries with the worst blackening

The darkest Asian country is Japan. There is a lot of news about black Japanese on the Internet. The number of blacks in Japan is very small, and there are many black groups in Japan. The black American soldiers left behind in their early years have made the black community grow particularly fast. Incomplete statistics show that there are 500,000 black groups in Japan. The value is not reliable, and it contains some water. 10 years ago, Japan revised its immigration policy and laid off many black groups, which may have led to few reports on Japanese blacks.
