kokujin

A japanese word that roughly translates to "black person" with "koku" being the color black (or dark) and "jin" meaning man (although gender is typically neutral). The word kokujin is not derogatory unlike the word kurombo and should also not be confused with gaikokujin (non-japanese person).

Black kokujin or white hakujin, they are both foreign gaikokujin.
