Why does Naruto use his mother's family name? Is there any logical and canonical reason to why Naruto used his mother's family name, Uzumaki, instead of his father's family name?
According to the Naruto Wiki:


  Suddenly orphaned, Naruto was left to grow up knowing nothing of his parents, receiving only his mother's last name as Hiruzen believed it was best that nobody knew that he was related to the Fourth Hokage.
