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.
The three main reasons for Hiruzen giving Naruto his mother's surname Uzumaki were to protect the village, Naruto, and the kyuubi.
Like the other posts stated, giving him the name Namikaze will make him a target for his father's enemies.
But there is more to Uzumaki name than just that. Hiruzen understood that the mysterious masked man (Tobi) didn't attack Minato Namikaze. What Tobi did was attack the kyuubi. And a fashionable trend seemed to be having the jinchuuriki as the Kage's son, for example Gaara was a jinchuuriki and his father was the Kazekage. So by giving Naruto the Uzumaki surname, this made Naruto + the kyuubi safer from anyone after the kyuubi.
Hiruzen also made sure to conceal the information about Naruto altogether, as shinobi that knew about the attack (on the kyuubi) were not allowed to talk about it (hence many people not knowing Naruto is Minato's son).
My extra 2 cents : This all ties well with Naruto's personality, as the Uzumaki nature (brash personality, powered by will and conviction) better suits the main character of a shounen compared to the Namikaze depiction (Genius, excels at everything). Maybe I give Kishimoto too much credit, but I feel like he had this all planned out (with Naruto being the son of the fourth, yet having his mother's name and personality).
The reason why Naruto has his mother's last name is because if people found out Naruto was the son of the fourth Hokage, he would have been in danger. This was actually explained to Naruto by Minato Namikaze the fourth Hokage himself in episode 168 of Naruto Shippuden. Naruto got to punch his dad in the stomach which was very funny even if he was mad at him.
I think a child's last name depends on what clan it has been born in. Naruto Uzumaki therefore show that he's a Uzumaki clan member. Just like Kushina Uzumaki, Naruto's mom. The preference of Uzumaki over Yamikaze is probably because the Minato and Kushina wanted to make Naruto less recognisable in public, as he is the 9 tail Jinchūriki and will be on the hitlist of many groups and organizations such as the Akatsuki.
- Sasuke Uchiha comes from the Uchiha clan.
- Hinata Hyuga comes from the Hyuga clan and so on.
Hiruzen(the third Hokage) Decided to put Naruto's Surname as Uzumaki because the Uzumaki was a clan which has Split after the village was destroyed,which meant that Most of the Uzumakis were refugees, which meant that it would be harder to confirm that Naruto was Minato's child(although he has yellow hair instead of the trademark red hair of the Uzumaki's), Secondly, the Namikaze from what I see on the wiki was a clan that was located in konohakagure,and Minato was the only famous Namikaze(once again,Wikipedia.),so If Naruto was given Namikaze, it would be easier for Anyone hunting for the Kyuubi or getting revenge to Find Naruto and Kill/hold him hostage, which would put the village in jeopardy.Thirdly, Hiruzen wanted to give Naruto a normal life(which he failed because of mizuki =_=).
I feel like Naruto was given Uzumaki was because of these reasons:
- Hiruzen just didn't want another attack on Konohagakure involving Naruto.
- The main character would be killed/taken hostage by groups (Akasutki, etc.)
- Naruto would be constantly on the run (making the story intense yet boring)
- Naruto wouldn't have met all the characters besides Akatsuki members (when Masashi Kishimoto made them)
