Everyone should have watched "Naruto". This is a very good cartoon that accompanied our childhood. The image in "Naruto" left a deep impression on us. There are many powerful characters among them, and the characters in the Naruto clan are all very powerful. Among them, Uzumaki Naruto and Uzumaki Boruto, they have always had a topic that attracted us to discuss. That's why Uzumaki Naruto followed his mother's surname, Uzumaki, instead of his father's surname, Namikaze, while Boruto followed Naruto's surname.
? Everyone also knows that Naruto’s father is named Namikaze Minato. Naruto is the fourth generation of Hokage. Everyone said that Naruto was given the surname Uzumaki to protect Naruto, because when Naruto was born, his parents died and no one protected him, and so did Minato's enemies. There are many. They were afraid that Naruto would be harmed, so they let her take her mother's surname, and her mother's clan had powerful sealing techniques, which the ninjas feared. This is one of the reasons why he took his mother's last name, and since his birth was concealed, he took his mother's last name.
Being in the spotlight is also a very scary thing. He is the fourth generation Hokage. When Naruto was born, his father Namikaze Minato had to seal the Nine Tails in him, so he took his mother's surname. Otherwise, everyone knows that the Nine-Tails is in Naruto and is the Jinchuuriki of the Nine-Tails, and the Nine-Tails is what everyone is fighting for, so if he follows his father's surname, everyone knows that he is the fourth generation Hokage. Possessed on his body, he became a target and was hunted by many people. So giving him his mother's last name was to protect him. And his son Boruto followed his surname because he could protect Boruto's safety, and this surname would not be pursued by many people.
? This is just one of the ways to protect Naruto. There are many other reasons passed down from legend, it’s up to you to understand the specific ones.
