>>279628568Naruto is a mishmash of a world so we don't know, I do think Kishimo was somewhat inspired by black people for the dark skinned people of the cloud village.
Does Naruto have 'white' heritage? I don't know, but I tend to think of the people of this world as their own races that don't fully correlate with the real world.
So in that sense I think of the Raikage as both black and not black.
