So remember that even the companions of the Messenger were from different races, and no matter what nation a group of people were from, no matter what race - Allaah sent that nation messengers from among themselves, and among them messengers and prophets, prophets who are of a higher level than us [no matter what race we're from.] So Allaah may have sent messengers to the japanese, to the europeans, to the africans, to the egyptians, to the arabs etc.
This is proven in the Qur'an, when Allaah says:
And We sent not a Messenger except with the language of his people, in order that he might make (the Message) clear for them. Then Allah misleads whom He wills and guides whom He wills. And He is the All-Mighty, the All-Wise. [Qur'an Ibrahim 14:4]
May Allaah make the path to paradise easy for you, and us all. ameen.
