The One Piece has been running for a very long time. In the 25 years since it started, countless other stories have come and gone.  People who were teens when first reading the manga are now parents. However, Eiichiro Oda has announced that One Piece is ending soon, and many fans sadly yet excitedly await the conclusion of their beloved series.

Of course, One Piece isn't the only long-running manga out there. These manga are still ongoing, despite nearly being as old as One Piece (or even older). While they aren't about pirates, they're just as exciting as Luffy's adventures.

The Prince of Tennis initially started as a grounded sports manga with a strong foundation in real tennis techniques. As the years went on, however, each character developed more and more absurd techniques. However, it's always in service of an exciting story.

Pokemon Adventures (1997)

Pokemon Adventures is authored by Hidenori Kusaka and starts in volume 10, illustrated by Satoshi Yamamoto. The story follows the adventures of the various Dex Holders from the games, and so each generation has a different character to follow in the world of Pokemon.

Pokemon Adventures is a generally faithful adaptation of the franchise, but it does stand out for one reason. Pokemon Adventures is significantly darker and grittier than the generally lighthearted tone of the games. While it's still in the realm of fun kids' manga, a few moments here and there make the reader terrified of the Pokemon world.

Baki The Grappler (1992)

Grappler Baki with the other fighters

Baki the Grappler is a martial arts action manga written and illustrated by Keisuke Itagaki.  The story focuses on Baki Hanma, a young man who is on a quest to become the strongest man in the world. Unfortunately for him, the strongest man in the world is his father. Brutal and ruthless, Yujiro Hanma has no intention of giving up the spot so easily.

Baki the Grappler is most well-known for its artistic license on grounded martial arts techniques and absurd muscle anatomy. It is pure testosterone-fueled martial arts beatdowns, and fighting is just as much a language for the reader as the text is.

Detective Conan (1994)

Detective Conan is a mystery-adventure manga written and illustrated by Gosho Aoyama. It begins with Shinichi Kudo, a young detective on the rise, suddenly being turned into a child via an experimental drug. Taking on the alias of "Conan Edogawa" (a portmanteau of two famous mystery authors), he uses the detective agency of Kogoro Mori to solve crimes and find the people who made him a child.

Detective Conan has remained quite consistent with its formula, and yet fans are still in love with it 28 years into the franchise.  For fans of detective shows such as Columbo, Detective Conan is the perfect story to follow.

Dragon Ball Franchise (1986)

Dragon Ball (and its many spinoffs) is illustrated and written by Akira Toriyama. It follows the story of Goku, a Saiyan adopted by a kind old man, who instills within him compassion for life as well as a passion for fighting. The entire saga follows his growth from a boisterous child to a fighter of gods.

Dragon Ball is a unique case. It ended its manga run in 1995, a respectable 9-year run, and only got a continuation in 2015, with Dragon Ball Super. Hilariously, the push for this revival was thanks to the awful adaptation Dragonball: Evolution. Toriyama feared the movie becoming his legacy, and decided to save his franchise before it was too late.

Kung Fu Boy (1983)

Kung Fu Boy (or Ironfist Chinmi) is a martial arts manga written and illustrated by Takeshi Maekawa. The story follows Chinmi, a busboy for a restaurant who is a martial arts prodigy. He trains under the legendary master You Sen, and after he is tasked with fighting a renegade student of his, the adventures truly begin.

Kung Fu Boy is a simple and traditional story about a student becoming a master. While it's by no means a unique story, that simply lends itself to a long-running franchise with a clear passion for Chinese culture.

Hajime no Ippo (1989)

Hajime no Ippo is a boxing manga written and illustrated by George Morikawa. The story follows Ippo Makunouchi, a mild-mannered boy who spends his free time helping with their fishing boat business. One day, after being rescued from bullies by a huge man named Takamura, Ippo is discovered to have a powerful punch, and so his journey as a boxer begins.

Hajime no Ippo, in terms of raw chapter count, is among the longest by far, reaching over 1,300 chapters as of 2022.  Boxing is one of the best ways to tell amazing stories. It is no surprise that fans still follow Ippo's growth as a fighter throughout the series, win or lose.

Jojo's Bizarre Adventure (1986)

Jojo's Bizarre Adventure is a manga written and illustrated by Hirohiko Araki. The lack of a given genre is because Bizarre Adventure refuses to be locked into any particular genre. It has run the gamut from Victorian-era horror to world-trekking adventure to mystery slice of life. The only constant throughline is each entry follows a member of the Joestar family.

Jojo's Bizarre Adventure is fueled by Araki's refusal to be stagnant. The art and writing evolve, being more impressive and bizarre than the last. Each entry is vastly different from the last, and that diversity in stories is why so many fans continue to follow Araki to this day, 37 years later.

Captain Tsubasa (1981)

Captain Tsubasa is a football manga written and illustrated by Yoichi Takahashi. It follows the story of Tsubasa Ozora, a boy with a natural affinity for football. He dreams of reaching the world stage to show his talents to the world and his love for the sport. From school tournaments to the World Cup, Captain Tsubasa is the most extended love letter to football ever made.

Captain Tsubasa is an incredibly influential manga.  The manga is so influential that it has been cited by talented football players such as Zinedine Zidane and Fernando Torres as one of the matches that lit their passion for the sport in the first place. There's no higher praise for a sports manga than being namedropped by the best athletes in the world.

Kinnikuman (1979)

Kinnikuman is a wrestling manga written and illustrated by the duo Yoshinori Nakai and Takashi Shimada (known collectively as Yudetamago). That's a lot of very Japanese words, but it makes sense as Kinnikuman is a very Japanese manga. It started as a parody of the then-popular Ultraman TV series, but slowly became a genuine story about wrestling and how it's used to save the world.

Japan loves their pro wrestling, their shonen, and parodying random things. Kinnikuman does all that and has an exciting story that gets crazier and crazier with each installment. It's a wild ride, but the bulging muscles and awesome action have kept fans on board for over 40 years.
