If you’ve spent any time on the internet over the last two decades, you’ve seen the straw hat. You’ve seen the stretchy pirate. You’ve probably heard about the "One Piece" being real. But when people ask who wrote One Piece, the answer isn't just a name on a cover. It’s a man who has essentially sacrificed his sleep, his health, and his entire adult life to create a modern epic.
That man is Eiichiro Oda.
He isn't just a writer. He’s the architect of the best-selling manga series in history. Honestly, it’s hard to overstate how much of a titan he is in the world of Japanese media. Since 1997, he’s been churning out chapters almost every single week. While most people would have burned out by year five, Oda is still going strong nearly thirty years later.
The Man Behind the Straw Hat
Eiichiro Oda was born in Kumamoto, Japan, in 1975. Most kids want to be astronauts or firemen. Oda? He decided he wanted to be a manga artist at age four. Why? Because he didn’t want to get a "real job." It’s kinda funny when you think about it, considering he now works harder than almost anyone on the planet.
He was obsessed with Vikings as a kid, mostly thanks to a TV show called Vickie the Viking. That spark eventually grew into the pirate world of Monkey D. Luffy. Before he hit it big, he worked as an assistant for other legendary creators. He helped out Nobuhiro Watsuki on Rurouni Kenshin. You can actually see some of his early influence in the art style of those older series.
Then came Romance Dawn.
That was the prototype. It was a one-shot story about a pirate named Luffy. It didn't quite land the first time, but Oda didn't quit. He refined the concept, tweaked the characters, and in 1997, Weekly Shonen Jump published the first chapter of One Piece. The rest is history.
Is It Just Oda or a Team?
When we talk about who wrote One Piece, we have to address the "assistant" factor. In the manga world, artists usually have a team. But Oda is famous—or maybe notorious—for his "hands-on" approach.
He has a rule.

He draws everything that moves. This includes all the characters, the animals, and even the smoke and clouds. Most manga artists delegate things like backgrounds or crowd shots to their assistants. Oda? He wants to maintain the "soul" of the drawing. His assistants usually handle the technical stuff like applying screentones, drawing the borders, or doing some of the static architecture.
It’s an insane workload. There are stories from his editors about Oda’s schedule. We’re talking about four hours of sleep a night. He stays in his studio for days on end. He’s been hospitalized for overwork before. In 2013, he famously apologized to fans for taking a break while he was being treated for a peritonsillar abscess. Even then, Masashi Kishimoto (the creator of Naruto) reported seeing Oda drawing new chapters from his hospital bed.
That’s the level of dedication we’re talking about here.
The Creative Genius of World-Building
What really sets Oda apart isn't just the art. It’s the writing. People often underestimate the complexity of One Piece because it looks "cartoony."
But it’s a political drama. It’s a historical mystery. It’s a commentary on systemic oppression and the nature of freedom. Oda plants "seeds" (foreshadowing) that don't bloom for fifteen years. For example, a character mentioned in a throwaway line in Chapter 100 might suddenly become the focal point of the story in Chapter 900.
He doesn't forget anything.
He keeps massive notebooks filled with ideas for every island and every side character. His world feels lived-in because it is. Every island has its own climate, its own currency, its own distinct government, and its own unique history. When you read it, you feel like the world exists even when Luffy isn't there.
Why Oda’s Style is Different
A lot of manga artists try to make their characters look "cool" or "edgy." Oda went the other way. He likes things to be "weird." He gives characters strange body types, bizarre laughs (like "Zehahaha" or "Gishishishi"), and powers that seem useless at first—like being made of rubber.

It was a gamble.
At the time, the trend was more realistic or "pretty" art. Oda stayed true to his vision. He wanted a story that felt like a grand adventure, not a brooding battle manga. That’s probably why it has such a massive global appeal. It’s weird, it’s heartfelt, and it’s unapologetically imaginative.
The Cultural Impact of Oda’s Work
You can’t talk about who wrote One Piece without mentioning the records he’s broken.
- One Piece holds the Guinness World Record for "the most copies published for the same comic book series by a single author."
- It has sold over 500 million copies worldwide.
- It has surpassed the sales of Batman and is closing in on Superman.
But for Oda, it’s not really about the numbers. He’s known for being incredibly humble. He rarely makes public appearances. He doesn't show his face in interviews, often using a cartoon avatar to represent himself. He wants the work to speak for itself.
He also interacts with his fans through a column called "SBS" (Shitsumon o Boshu Suru), which translates to "I am taking questions." Fans send him letters, and he answers them with a mix of lore details and incredibly dirty jokes. It shows a human side of a creator who is often treated like a god by his fanbase.
Misconceptions About the Writing Process
A lot of people think Oda is making it up as he goes.
Nope.
He has known the ending of the series since the very beginning. He told his editors the ending years ago just in case something happened to him. While he might change the path to get there—like how the "Seven Warlords" weren't originally supposed to be in the story—the destination has remained the same for over 25 years.

There’s also a myth that he does everything alone. While he is the primary creator, his editors play a huge role. They act as sounding boards. They tell him when a chapter is too cluttered or when a joke doesn't land. But at the end of the day, every major plot beat and every line of dialogue comes from Oda’s pen.
How to Appreciate Oda’s Work Today
If you're just getting into it, the sheer size of the series is terrifying. Over 1,100 chapters. Over 1,000 anime episodes. It’s a mountain.
But here’s the thing: you don't "catch up" to One Piece. You live with it.
The best way to experience who wrote One Piece is to read the manga. The anime is great for the music and the voice acting, but the manga is where Oda’s specific "vibe" is most pure. The pacing is better, and the art is exactly how he intended it to look.
Actionable Steps for New and Old Fans
If you want to dive deeper into the mind of Eiichiro Oda or the world he created, here’s what you should do:
- Read the "Color Walk" Art Books: These aren't just collections of drawings. They feature interviews between Oda and other famous creators. You get a real sense of his philosophy on art and storytelling.
- Follow the "SBS" Columns: If you’re reading the volumes, don't skip the Q&A pages. That’s where the most dedicated fans find the "deep lore" that Oda doesn't have room for in the main chapters.
- Watch the Netflix Live Action: Surprisingly, Oda was heavily involved in this. He had "veto power" over everything. Watching it shows you what he considers the "core" of his story when translated for a Western audience.
- Pay Attention to the Cover Stories: Oda uses the first page of many chapters to tell "mini-stories" about characters we haven't seen in a while. These aren't just filler; they often predict major world events that happen hundreds of chapters later.
Eiichiro Oda is a rare breed. In an era of "content" created by committees and algorithms, One Piece remains the singular vision of one man who just really likes pirates. He’s nearing the end of his journey now. The "Final Saga" has officially begun. Whether you’ve been there since the start or you’re just starting now, there will likely never be another creator quite like him again.
The best time to start was 25 years ago. The second best time is today.
