there are many blacks (African-American) born in Japan on the us military bases (not considered japan for citizenship) and at Japanese civilian hospitals to American couples
if an African-American and a Japanese have a child in a Japanese hospital and if the American has a working, student, permanent resident, or any other visa that states he/she is legally entitled to reside in the country the child is of American and Japanese citizenship. once the Japanese spouse enters the child's name on the Japanese family registry, the child is Japanese as far as japan is concerned. the us embassy can record the birth if both parents complete necessary paperwork but if they do not, the American side basically will have no idea if the child is to be counted/considered American, especially if the American parent does not apply for a passport for the child.
there are many africans and others that may be considered "black" --remember Black is not a nationality-- that marry Japanese but their offspring are deemed foreign by the average Japanese.
as far as tracking the numbers of "black people" that are born in japan and considered citizens, it will be a difficult task since most documentation will show the nationality of the foreign spouse.
Yes, there are black people in Japan.
The Japanese people aren't black themselves, but there are probably some black people that live in Japan.
Because black is a bad color
Of course they can - and do.
Of course!
There is no way to tell how black people are treated in Japan. These people are not often seen but every Japanese will treat someone differently.
The US state with the highest proportion of black residents is Mississippi, at 37.18%(1,092,588 people). As to how many of those black people are citizens, and how many permanent residents I cannot answer, but I'm guessing that the majority are citizens.
You asked if they are black or black. Uh...
Black people
0.0% is black, there are around 120 million black people.
They are black people.
As soon as they are born on US soil...
