There is a running joke on the internet that One Piece is “infinite.” With over 1,100 episodes, Eiichiro Oda’s work seems like an unclimbable mountain for new fans. However, in Japan, Luffy and his crew are still considered “rookies” when compared to the true titans of television.
Unlike action anime (shonen) that have a linear story, the longest-running anime in history are mostly family comedies or children’s shows (kodomomuke), designed to last for decades. Based on official broadcast data, we compiled the true Top 5 that makes One Piece look like a miniseries.
1. Sazae-san (The World Record Holder)
Premiere: 1969 | Status: Ongoing Episodes: 2,800+ (with over 7,000 story segments)
It’s not just an anime; it’s a Japanese cultural institution. On air uninterruptedly since the year man landed on the Moon, Sazae-san holds the Guinness World Record for the longest-running animated series. The show depicts the daily life of Mrs. Sazae and her family, focusing on traditional Japanese values. It is so influential that economists analyze the “Sazae-san Syndrome”: the depression Japanese people feel on Sunday evenings when the anime ends, signaling the weekend is over.
2. Nintama Rantaro (Ninja Boy Rantaro)
Premiere: 1993 | Status: Ongoing Episodes: 2,500+
While the Western world associates ninjas with Naruto, Japanese children grow up watching Nintama Rantaro. With short 10-minute episodes, the series focuses on three little ninja apprentices (Rantaro, Kirimaru, and Shinbei) at a ninjutsu academy. The focus here isn’t world wars or mystical powers, but slapstick humor and the protagonists’ constant failures to become competent ninjas.
3. Ojarumaru (Prince Mackaroo)
Premiere: 1998 | Status: Ongoing Episodes: 2,127+
This anime tells the story of a 5-year-old prince from the Heian Era (which occurred a thousand years ago) who time-travels to modern Japan. Ojarumaru is a staple of NHK (Japan’s public broadcaster). The show’s longevity is due to its simple and charming “fish out of water” premise, showing the culture shock of an ancient prince dealing with current technology and customs, all in quick 10-minute doses.
4. Oyako Club
Premiere: 1994 | Status: Finished (2013) Episodes: 1,818
Although it ended in 2013, Oyako Club remains an animation colossus. With very short 5-minute episodes, the series functioned almost like an animated “newspaper strip,” focusing on funny and heartwarming interactions between family members. Its huge episode count is due to its daily broadcast for nearly 20 years, creating a routine bond with the audience.
5. Doraemon (1979 Version)
Premiere: 1979 | Status: Finished in this version (2005) Episodes: 1,787
Before the current reboot (which already exceeds 1,300 episodes), the classic Doraemon series, aired between 1979 and 2005, set an unreachable standard. The robot cat from the 22nd century who goes back in time to help the clumsy Nobita is possibly the most famous character in Asia. With nearly 1,800 episodes in this specific run alone, Doraemon easily surpasses One Piece and Detective Conan, cementing itself as a pop culture legend.
Where does One Piece stand?
For comparison, One Piece (started in 1999) currently has about 1,120 episodes. While impressive for a continuous adventure series, it would need to air for another 30 uninterrupted years just to get close to where Sazae-san is today.
