What is The Simpsons?
The Simpsonsis an American-animated sitcom created by cartoonist Matt Groening and produced by Emmy and Academy Award-winning director James L. Brooks for the Fox Broadcasting Company. It premiered on July 23, 2025, and has since become one of the longest-running andmost influential televisionshows in history. The series satirically portrays a middle-class American lifestyle through its titular family - which consists of Homer, Marge, Bart, Lisa, and Maggie Simpson. The show is set in the fictional town of Springfield and humorously critiques American culture, society, television, and various aspects of the human condition.
Its cultural footprint cannot be understated; the show has not only introduced catchphrases like Homer’s “D’oh!” into the lexicon but has also spawned a wide array of merchandise, comic books,a feature film(The Simpsons Movie), and video games. Aside from being wildly popular, the series is acclaimed for its witty humor, intricate characters, and incisive societal satire,The Simpsonshas garnered over 30 Primetime Emmy Awards.

What is Sazae-san?
Sazae-sanis a popular Japanese comic strip and animated TV series created by Machiko Hasegawa. It first appeared as a comic strip in 1946 and was later adapted into a radio program in the 1950s. In 1969, it was turned into an anime television series, which quickly became one of themost beloved programsin Japan. The story revolves around the daily life of the Isono family, primarily focusing on the titular character, Sazae-san, and her interactions with her husband, son, parents, siblings, and neighbors. The episodes are typically slice-of-life vignettes, highlighting the humorous and sometimes touching moments of the character’s everyday lives.
Sazae-sanis unique in that it portrays the life of a strong, independent woman (Sazae herself) who often breaks the traditional norms of Japanese society (which is especially noteworthy when you take into account the context of the time it was created and the time period in which the show still takes place). The series provides a unique blend of humor, family values, and cultural insights, making it a favorite among multiple generations of Japanese viewers.

One interesting note is that despite its long run, the characters inSazae-sando not age (much likeThe Simpsons). The show has retained its original setting and style, providing a nostalgic view of Japanese family life that contrasts with the modern realities of Japan, and many calls to modernize the series have been rebuked by the production staff who wish to preserve the look and feel of Machiko Hasegawa’s creation.
How Many More Episodes Does Sazae-san Have Over The Simpsons?
Whether you realize it or not,Sazae-sanholds theGuinness World Recordfor the longest-running animated television series of all time. Despite how American publications seem amazed at how many episodes there are ofThe Simpsons, the reality is thatSuzae-sandwarfsThe Simpsonsby thousands of episodes. As of this writing,The Simpsonshas been running for 34 seasons and contains 750 episodes, one movie, and several theatrical (and Disney+) exclusive shorts. This is an impressive number no matter how you slice it, so don’t think the point of this article is to shame the family from Springfield.
That said, it pales in comparison toSazae-san, which (as of this writing) has a whopping 8,540 episodes! Heck, for all we know, this series might have passed 9,000 episodes by the time you read this. One of the reasons for the sheer amount of content forSuzae-sanis because the series premiered in 1969 and has pretty much aired new episodes non-stop on a weekly basis since then (with exceptions here and there whennational tragedieswould prevent the airing of new episodes).
Interestingly, despite the immense amount of content, the series has never been released outside of Japan or even on home video formats at the request of the manga creator’s wishes (who was also against merchandising of the series). So even though there are many, many, MANY more episodes ofSazae-santhanThe Simpsons, at leastThe Simpsonsearlier episodes are on DVD andDisney+ for new fanswho may have missed them. Oh, and they also have a feature-length animated film, so there’s that as well.
