Apart from Dragon Ball Z, I would say that Naruto is the most famous anime in the world. The main character of the series, as you all know, is Naruto Uzumaki. He is a very famous character, but I still don't think you know the following facts.
1. HIS FAVORITE RAMEN STORE IS REAL
If you watch the anime, you will find out that Naruto has a favorite ramen store. The official name of this store is Ichiraku, but did you know that it exists in real life? It is actually a store located in Kyushu, very close to the university where the author graduated.
2. KANKURO'S HAIR LOOKS LIKE NARUTO'S
I know this is probably a trivial fact, but it's still funny. Kankuro, a character in the anime, has a very mysterious and unique look. However, you will notice that once his hood is removed, he has the same hairstyle as Naruto.
3. NARUTO WAS NEVER GOING TO BECOME A NINJA
Yes, the famous ninja was never actually supposed to be one. The author had originally intended him to use magic rather than ninjutsu. However, the author felt that this would be too confusing and so he became a ninja.
4. THE ANIME WAS ALMOST CANCELLED
Can you imagine that this story was never made into an anime? It was almost a reality because a certain organization was not very satisfied with the number of deaths in the series. So they filed a complaint and asked the sponsors to withdraw their funding. Fortunately, the series was still made and people have enjoyed it for years.
5. SANJI WAS ALSO GOING TO BE CALLED NARUTO
Although this fact is not strictly related to him, it is a bit. If anyone has watched One Piece, they know who Sanji is. In fact, it was intended that he be called Naruto. However, the two series were released at the same time and the author changed his name to Sanji.
