Look at this discussion, it's been done many times, but for the Japanese it doesn't matter the color of hair and eyes in a drawing, for them a character is Japanese unless otherwise indicated by the mangaka or the studio.
This is how you have cases like Sailor Moon, a blonde girl with blue eyes is really Japanese, or the case of Takenori Akagi from Slam Dunk, a dark-skinned 6'5'' Japanese teenager.
If it's any consolation the only non-Japanese MCs to date are Serena, Calem and Leon(Wes), the others were created as Japanese kids traveling to other parts of the world.
