This generation of anime fans is used to 12 or 24-episode format for anime series. But that wasn’t the case decades ago when anime kept airing episode after episode without any delay. Some of them can be the Dragon Ball series, Naruto series, etc. But the thing with long-running animes is that it has the potential to connect viewers with their characters in deeper ways than short shows. Just to give you a gist, below are the Top 10 anime series with the most number of episodes.

But before going into the list, One Piece, and Gintama, are some shows with hundreds of episodes, which can be shocking for fans that these aren’t the longest-running anime of all time. Some series have aired thousands of episodes and are still airing new ones to date. But the thing is, these shows rarely leave Japan and come into sight of the mainstream community.

Alright then, now let’s move on to the Top 10 anime series with the most episodes. Here’s a quick overview of all the shows that we will be talking about:

The only show that belongs to the post-2000s anime era, Deluxe Da yo! is a slice-of-life ONA that started airing in 2019. One of the reasons why this show has many episodes within a short span of time is that each episode is only 2 minutes long.

This anime can be said to be a redo of the first show with a similar name. The story is fairly simple, it follows the day-to-day life of a man named Kamoyama. He ends up working as the Sales Department Z’s manager – for shellfish!

9. One Piece

Luffy’s high seas adventures have had a clear goal from the very beginning to find the elusive treasure and become the Pirate King. You’d think taking so long to get there would drag things out, but amazingly this series only manages to top itself again and again.

One Piece celebrated the anime’s 1000th episode in 2021, an achievement that shows the dominance of this shonen anime over the last two decades. This ever-growing world feels as alive as our own.

You might think that the anime’s greatest detective would have solved his own body-swapping dilemma by now. But thanks to a fresh twist and good-hearted humor Shinichi Kudou has been left in a child’s body for over 25 years.

Detective Conan or Case Closed as it is known in the west, follows the story of a man, who one day wakes up with a body of a 7-year-old boy! This amazing mystery manga by Gosho Aoyama is still strong and can nearly take 100 tankobon more volumes to its name.

Crayon Shin-chan is another long-running anime that most fans might be familiar with its popularity. The series follows Shin-chan and his daily adventure alongside his family and friends. This show is full of clever quips, crude humor, and even occasionally lewd jokes.

Despite that Crayon shin-chan was almost pulled from TV after just two years, but its unprecedented success allowed it to hold onto its time slots. And since its airing to this day, we can say that it was a good move. The series’s popularity has also led to many spin-offs as well as films and games.
