The 20th anniversary of the anime will be celebrated with some brand-new episodes, according to the Naruto website.

The episodes billed as “a new anime project,” are scheduled to debut in September and will consist of a total of four all-new episodes. No additional information was provided about the time period the episodes will take place or the personalities that would be present.
According to Anime News Network, as part of the anniversary celebrations, a few older episodes of the Naruto anime will begin airing on Japanese television in July.
On October 3, 2002, the Naruto anime debuted in Japan. Until early 2007, the first season of the anime, simply titled Naruto, covered Part 1 of the manga. After that, the plot underwent a time jump. The series’ name would subsequently change to Naruto: Shippuden and it would start covering Part 2 of the manga. This lasted until 2017 when it came to an end. Boruto: Naruto Next Generations then took its place.
While he aspires to become in charge of the Village Hidden in the Leaves, the series follows the titular ninja. Since its release, Naruto has gained enormous popularity and, together with One Piece and Bleach, has become one of Shonen Jump’s renowned “Big Three” series of the mid-2000s.
