30 Anime with the Most Episodes – Ranked!

Modern-day anime are tame in terms of how long they run. A majority of new-gen anime stick to 12-24 episodes per season. 

Of course, that’s what fans want these days. 

Fans want anime that they can binge-watch in a day or two and move to the next one. So, we can’t really complain or blame the production studios too much. 

But what about otakus like us who grew up watching shounens like Naruto, Bleach, Gintama, One Piece, and countless other anime with hundreds and thousands of episodes? 

We’ve developed a thing for long-running anime, and there’s no turning back. 

Thankfully, there’s plenty to chew on.

So, without further ado, here are 30 anime with most anime episodes that would take years to finish.

What do you think? What is the longest anime series?

If you said One Piece, you’re wrong. One Piece isn’t even close to being the anime with the most anime episodes.

Read on, and prepare to be surprised.

If you’re looking for some classic comedy anime, I’ll suggest KochiKame.

This long-running anime follows Ryotsu Kankichi, a lazy, fugly, greedy, but sweet cop from a small police station in DownTown Tokyo.

The anime is based on Osamu Akimotos’ manga of the same name, which began publishing in 1976. And if you’re wondering why it took so long to get an anime, it’s because the mangaka wanted it to be a live-action film and not an anime.

  • Production Studio: Xebec, OLM
  • Release Date: March 29, 2010
  • Status: In Production

Some anime never really make it big outside of Japan, and Hanakappa is one of those. But, the series is still as popular as ever in Japan. That’s why it’s been running for over a decade.

Hanakappa is a manga and anime series about a Japanese folklore character, a Kappa. Kappas are adventurous creatures, and Hanakappa is no different. 

But, what makes Hanakappa unique and a target of evil are the special powers granted to him by a unique flower on his head.

Just like some anime fail outside of Japan, some garner a worldwide audience, and Ninja Hattori-kun did the latter.

Nickelodeon and Disney introduced Ninja Hattori-kun to children from every corner of the world. USA, UK, Australia, and Canada got the English dub on Netflix (removed in 2020), whereas Amazon Prime Video still streams Ninja Hattori-kun in India and a few other countries.

Within those animals is Shimajiro, a young tiger cub who attends Kindergarten and discovers new things in every episode.

19. Asa da yo! Kaishain – 744 Episodes

asa da yo kaishain all episodes
  • Production Studio: DLE
  • Release Date: April 4, 2016
  • Status: Finished

Asa da yo! Kaishain (It’s Morning! Clamployees) started as interval animations representing stereotypical employees in a Japanese workspace. 

There’s no storyline to follow, no set premise. It’s just a bunch of shellfish that represent the various types of employees one could see in a Japanese office, or any office for that matter.

The shorts gained so much popularity among the Japanese audience that the producers kept creating and creating and creating…

18. Kotowaza House – 773 Episodes

kotowaza house
  • Production Studio: Eiken
  • Release Date: April 4, 1987
  • Status: Finished

Kotowaza House was a proverb-of-the-week anime set around a salaryman, Peter.

This public-service anime would air 5-minute episodes every weekday. 

Every episode will start with Peter doing something that doesn’t sit well in Japanese culture. And then, by the end of the episode, he’d be corrected and educated by his friends and family.

You’d think they’d run out of proverbs after a few weeks, but the series went on for 5 years.

17. Sekai Monoshiri Ryokō – 1,006 Episodes

Sekai Monoshiri Ryokō
  • Production Studio:
  • Release Date: October 1, 1971
  • Status: Finished

Another educational Japanese anime that aired during the 70s and has been completely forgotten is Sekai Monoshiri Ryoko (The Instructive Trip Around The World). 

The series is a documentary-styled animation with 5-minute episodes that take the viewer on a trip to famous places around the globe.

Much like many other anime on this list, Sekai Monosiri Ryoko also never made its way to the Western audience, and now it’s completely lost in time.

16. One Piece – 1,055 Episodes

one piece total episodes
  • Production Studio: Toei Animation
  • Release Date: October 20, 1999
  • Status: In Production

One of the most popular anime of our generation, many believe One Piece is the longest anime ever. And it’s a well-founded claim because the series has been running for nearly 24 years now.

The story of Luffy trying to become the King of Pirates is as entertaining and gripping as it was the day Luffy set sail for the first time. 

But, is One Piece the longest anime? Far from it! In fact, there are 15 more anime with more episodes than One Piece.

15. Case Closed (Detective Conan) – 1,077 Episodes

  • Production Studio: TMS Entertainment
  • Release Date: January 8, 1996

14. Crayon Shin-chan – 1,122 Episodes

Much like Ninja Hattori-kun, Crayon Shin-chan also garnered a global audience.

The series is about Shin-chan, a young prankster, who has some crazy adventures because of his outgoing and playful personality. 

He’s not alone, though.

Shin-chan has a colorful cast of friends and family by his side.

With a unique animation style and some peculiar voice acting, Shin-chan became an equally popular cartoon series among Asian and Western viewers.

13. Doraemon (2005) – 1,217 Episodes

This series only ran for 4 years but still managed to churn out 1,274 episodes. 

Monoshiri University: Tomorrow’s Calendar is another one of those educational anime series that got restricted to Japan. 

The anime has a 5-minute-episode format, and each episode will focus on a certain historical event.

Since it’s from the 60s, there’s no way to watch it now.

It just followed a family of five to convey public service messages and educate the audience with a 5-minute episode every weekday.

10. Manga Nippon Mukashi Banashi – 1,494 Episodes

  • Production Studio: Group TAC
  • Release Date: January 7, 1975
  • Status: Finished

Japanese folk tales turned into anime? Who could say no to that?

Gisaburo Sugii picked up the best of Japanese folk tales and turned them into an omnibus-format anime series. The stories and the fact that he used different animators for every episode made the series an instant hit.

Every episode would have felt fresh and exciting as if you were watching it for the first time. 

It’s a shame that the series is non-existent on the internet now.

9. Kirin Ashita no Calendar – 1,498 Episodes

kirin ashita no calendar
  • Production Studio:
  • Release Date: Jan 1, 1980
  • Status: Finished

Very little is known about Kirin Ashita no Calendar except for the fact that this is a sequel to another one of the longest Japanese anime series, Monoshiri University: Tomorrow’s Calendar.

Much like it’s a prequel, Kirin Ashita no Calendar also had the same format of 5-minute educational episodes about history.

And much like its prequel, Kirin Ashita no Calendar also was confined to the Japanese audience.

8. Chibi Maruko-chan – 1,501 Episodes

5. Doraemon (1979) – 1,787 Episodes

  • Production Studio: Shin-Ei Animation
  • Release Date: April 2, 1979
  • Status: Finished

Although the OG Doraemon series ended in 2005, it remains one of the top 10 longest anime series to date.

Quite frankly, if a show ran for 25 years and had as much of a viewership as Doraemon did, it’d be silly not to create this many episodes.

The show remains one of the most popular Japanese shows globally. And even though they ran out of manga material in 2005, the creators keep coming up with new adventures for Nobita and Doraemon.

4. Oyako Club – 1,818 Episodes

Oyako Club
  • Production Studio: Eiken
  • Release Date: October 3, 1994
  • Status: Finished

Oyako Club is a slice-of-life anime that follows two aliens and their day-to-day interaction with a human family.

Rompa and Lun are two Japanese-speaking aliens (because why not?) who end up living with a human family. As they learn the ways of Earth and introduce the family to their style of life, the show turns humorous and wholesome at times.

It’s kind of sad that the show never got a proper finale. No one knows whether the aliens returned home or stayed on Earth.

3. Ojarumaru – 1,947 Episodes + 7 Specials

  • Production Studio: Gallop
  • Release Date: October 5, 1998
  • Status: In Production

  • Production Studio: Ajia-Do

Nintama Rantarou follows 3 young shinobis, Rantaro, Shinbei, and Kirimaru. The 3 are first-grade students who love the Ninja culture and aspire to become the best Ninjas in the world.

Since the show is more kid-centric, fights and action take the back seat as comedy becomes the main theme of every 10-minute episode.

1. Mrs. Sazae – 2,640 Episodes

Here’s the answer to what anime has the most episodes- Mrs. Sazae.
