Introduction: A Secret 27 Years in the Making
For nearly three decades, one question has echoed through manga stores, anime conventions, online forums, and the hearts of millions of fans around the world:
“What is the One Piece?”
Since 1997, legendary manga creator Eiichiro Oda has guarded the answer like the greatest treasure in storytelling history. The mystery has survived more than 1,100 chapters, countless arcs, and decades of speculation. Entire YouTube channels, fan communities, and theory blogs exist just to answer that one question.
Over the years we have uncovered massive secrets of the One Piece world. We learned about the mysterious Void Century, the legendary figure known as Joy Boy, the hidden meaning behind the Will of D., and the shocking truth about Luffy’s Devil Fruit. Each revelation brought fans closer to understanding the world that Oda has carefully built.
Yet despite all these revelations, the ultimate treasure left by Gol D. Roger at the end of the Grand Line remained a mystery.
Until now.
In what might be one of the most dramatic and symbolic acts in manga history, Eiichiro Oda reportedly wrote down the final truth of the One Piece on paper, tore it in half, and sent part of it into the depths of the ocean.
This wasn’t simply a publicity stunt. It was something far more poetic.
Just like the treasure itself, the truth has now become something physically hidden in the real world — waiting for the moment when the story finally reaches its end.
The Event: Celebrating 600 Million Copies
The moment came during celebrations of a historic milestone. The One Piece manga recently surpassed an unbelievable achievement: over 600 million copies sold worldwide.
This number places One Piece among the best-selling comic series of all time, standing beside legendary works that shaped modern storytelling.
Since its debut in Weekly Shonen Jump in 1997, the story of Monkey D. Luffy and his dream of becoming the Pirate King has grown into a global cultural phenomenon.
What started as a simple pirate adventure has expanded into an enormous fictional universe filled with complex politics, ancient history, emotional character arcs, and philosophical themes about freedom and dreams.
The franchise’s impact spans multiple mediums:
- The long-running anime adaptation produced by Toei Animation
- Record-breaking manga sales worldwide
- Movies, games, and merchandise
- The globally successful Netflix live-action adaptation
Few fictional worlds have lasted this long while continuing to grow in popularity. But what truly keeps fans hooked is not just the adventure — it is the mystery.
The mystery of the One Piece.
And now Oda has made that mystery even deeper.
The “Ocean Burial” of the Secret
According to reports shared during the celebration video, Eiichiro Oda performed a symbolic ritual connected to the secret of the One Piece.
First, the legendary mangaka sat down and wrote the final truth of the treasure on a sheet of paper. This was not a vague hint or a metaphorical explanation. It was reportedly the complete answer to the question fans have asked for nearly three decades.
Then something dramatic happened.
Oda tore the paper into two halves.
One half remained with him.
The other half was placed inside a sealed chest and lowered deep beneath the ocean’s surface.
The depth was not random.
The chest was sunk exactly 651 meters underwater.
And according to the vow attached to this ritual, the chest will remain untouched until the One Piece manga reaches its final chapter.
In other words, the answer to the greatest mystery in anime and manga now physically exists somewhere in the ocean — hidden until the story concludes.
Why 651 Meters?
At first glance the number may appear random, but fans of One Piece know that Oda rarely chooses numbers without meaning.
The depth of 651 meters places the chest within what oceanographers call the Bathypelagic Zone.
This region of the ocean is often referred to as the “midnight zone.”
Sunlight cannot reach this depth. The environment is dark, cold, and mysterious — a perfect metaphor for the hidden history of the One Piece world.
In the story itself, the ocean depths have always played an important role.
The legendary Fish-Man Island sits nearly 10,000 meters beneath the sea. Ancient secrets are carved into Poneglyphs, stones that preserve history from a forgotten era.
By placing the secret at the bottom of the ocean, Oda is essentially creating a real-world Poneglyph.
Just like the characters in the story must travel across dangerous seas to uncover the truth, fans must now wait for the journey to reach its final destination.
The Promise: The One Piece is NOT a Metaphor
For many years one fear haunted the fanbase.
Some believed that after decades of adventure, the One Piece treasure might simply be something symbolic.
A lesson.
A memory.
Or the classic storytelling cliché: “The real treasure was the friends we made along the way.”
Eiichiro Oda has repeatedly rejected that idea.
In interviews, the author made it clear that the Straw Hats will receive a real reward at the end of their journey.
"I really hate that kind of ending. After going through such a long adventure, it would be unfair to not give them a proper reward."
This statement reassured fans that the One Piece treasure truly exists in a physical form.
And the ocean burial stunt seems to reinforce that promise.
If the final secret can be written down on paper and locked in a chest, then it must be something concrete — something that can be explained clearly.
This revelation has reignited one of the internet’s biggest debates.
What exactly is the One Piece?
Theories Are Exploding Across the Internet
The moment news about the buried secret spread, fan theories exploded across social media, YouTube channels, and discussion forums.
Some theories that were once considered unlikely are now being reconsidered. Others have gained new evidence thanks to recent developments in the manga.
With the final saga of One Piece now underway, every clue matters more than ever.
Below are some of the most fascinating theories currently circulating within the fandom.
Top 5 Theories: What Could Be Written on the Hidden Page?
Over the years, fans have proposed thousands of theories about what the One Piece treasure might actually be. Some are simple guesses, while others are incredibly detailed analyses that combine clues from hundreds of chapters.
With the secret now symbolically buried beneath the ocean, these theories feel more exciting than ever. Here are five of the most compelling possibilities.
1. The Red Line Destruction Theory
One of the most popular and widely discussed theories suggests that the One Piece is connected to the destruction of the Red Line.
The Red Line is the massive continent that divides the world into separate oceans. It separates the four seas — East Blue, West Blue, North Blue, and South Blue — and creates the dangerous Grand Line in between.
Many fans believe that the One Piece may be a plan, weapon, or mechanism designed to destroy the Red Line entirely.
If this happened, the world's oceans would merge into one unified sea.
In other words, the world would literally become “One Piece.”
This theory connects with many long-running story elements:
- The dream of Sanji to find the legendary All Blue, a sea where fish from every ocean gather.
- The mysterious ancient weapons like Pluton, Poseidon, and Uranus.
- The hidden history of the Void Century.
If the Red Line falls, the entire geography of the One Piece world would change forever. Nations would be united, the seas would merge, and the world government’s power structure could collapse.
Some fans believe that Gol D. Roger laughed when he found the treasure because he realized the plan was brilliant — but it required the right era and the right person to make it happen.
That person might be Luffy.
2. Joy Boy’s Final Message
Another fascinating theory suggests that the One Piece might actually be a message left behind by the legendary figure known as Joy Boy.
Joy Boy lived during the mysterious Void Century, a period of history that the World Government has tried desperately to erase. Only fragments of this lost history survive, preserved in the ancient Poneglyphs scattered across the world.
Some fans believe that the One Piece is the final part of this forgotten story.
Instead of gold or jewels, the treasure might be a record of the true history of the world — written by Joy Boy himself.
This theory would explain why Roger and his crew laughed when they reached Laugh Tale.
Perhaps the message revealed a truth so ironic, shocking, or hilarious that it made the entire crew burst into laughter.
If this theory is correct, the One Piece could be something like:
- A written story
- A comic-style chronicle
- A record exposing the lies of the World Government
Such a discovery would not only reveal the past but also completely reshape the future of the world.
3. The Secret of Bink's Sake
One of the oldest mysteries in One Piece is the famous pirate song known as Bink’s Sake.
The song has appeared multiple times throughout the series and is deeply connected to themes of friendship, freedom, and adventure.
Many fans believe that the lyrics of Bink’s Sake may contain hidden clues about the final treasure.
Some theorists suggest that the song could actually be a coded map or instructions leading to the true meaning of the One Piece.
Others believe the song symbolizes something deeper: the idea that pirates across the world share the same dream of freedom.
If the One Piece is connected to Bink’s Sake, the treasure might represent a moment where the entire world gathers together in celebration — a massive pirate banquet that symbolizes unity and freedom.
In a series where characters often celebrate with food, laughter, and music, this idea would perfectly match the tone of the story.
4. The World's Greatest Sake
Some fans interpret the clues more literally.
What if the One Piece is actually a legendary drink?
Throughout the series, sake plays a symbolic role in pirate culture. Sharing a drink represents trust, loyalty, and friendship.
Characters like Whitebeard, Shanks, and Roger often shared sake during important moments.
This has led to a playful but surprisingly convincing theory: the One Piece might be the world’s greatest sake — a drink meant to be shared at a massive celebration that unites the entire world.
Imagine the final scene of the story: pirates, kings, fish-men, revolutionaries, and ordinary citizens all gathered together in one giant festival.
Such an ending would perfectly reflect the core themes of the series — freedom, friendship, and joy.
5. A Secret Connected to the Moon
Another theory focuses on one of the most mysterious locations in the One Piece universe: the Moon.
In the Enel cover story arc, readers discovered that the moon once hosted an advanced civilization connected to the winged races of the One Piece world.
This revelation suggests that the history of the world might extend far beyond the oceans of the planet.
Some fans believe the One Piece might be connected to this ancient lunar civilization.
The treasure could be:
- Ancient technology
- A map leading to the moon
- A key to restoring a forgotten civilization
If true, this would expand the scope of One Piece from a pirate adventure to a cosmic story about humanity’s origins.
Why the Mystery Matters So Much
The secret of the One Piece is more than just a plot twist. It is the central pillar of one of the longest-running stories in modern entertainment.
For more than twenty-five years, fans have followed the journey of the Straw Hat Pirates across dangerous seas, mysterious islands, and world-changing battles.
Every arc has brought them one step closer to Laugh Tale.
But the journey has always been about more than just treasure.
It is about dreams.
Each member of the Straw Hat crew carries their own dream:
- Luffy wants to become the Pirate King.
- Zoro wants to become the greatest swordsman.
- Nami wants to draw a map of the entire world.
- Sanji dreams of finding the All Blue.
- Robin wants to uncover the true history of the world.
The One Piece treasure represents the point where all of these dreams intersect.
The Legacy of One Piece: 1997 – Present
To understand why the secret of the One Piece matters so much, we need to look at the incredible journey the series has taken since its debut.
What started as a pirate adventure in the pages of Weekly Shonen Jump has grown into one of the most influential stories in modern entertainment.
Below is a timeline of major milestones that shaped the legacy of One Piece.

Very few fictional stories last this long while maintaining such an enormous fanbase. Yet One Piece continues to grow because its core themes remain timeless.
Adventure. Freedom. Dreams.
The Final Saga Has Begun
In recent years, Eiichiro Oda confirmed that the story has entered its final saga.
This does not mean the series will end immediately. In fact, the final saga could still take several years to conclude. However, the narrative has clearly entered its final stage.
The Straw Hat Pirates are now closer than ever to reaching Laugh Tale.
The secrets of the Void Century are beginning to surface.
The Revolutionary Army is moving against the World Government.
And the world itself is beginning to change.
All of these threads will eventually lead to the moment that fans have waited for since 1997 — the discovery of the One Piece.
A Masterpiece of Long-Term Storytelling
One Piece is not just a manga series. It is one of the greatest examples of long-term storytelling ever created.
Eiichiro Oda has spent more than two decades crafting a narrative filled with interconnected mysteries, emotional character arcs, and hidden clues planted hundreds of chapters in advance.
Many of the questions introduced in the early chapters are only now beginning to receive answers.
This level of planning is extremely rare in modern storytelling.
By burying the secret of the One Piece beneath the ocean, Oda is reminding fans that the journey itself matters just as much as the destination.
Just like the Straw Hats must travel across the Grand Line to reach Laugh Tale, readers must travel through every chapter of the story to reach the final truth.
When the Truth is Finally Revealed
Somewhere, deep beneath the ocean's surface, a sealed chest now holds part of the greatest secret in anime and manga history.
651 meters below the waves.
Hidden in darkness.
Waiting.
When the final chapter of One Piece is eventually published, the world will finally learn the answer to a question that has lasted nearly three decades.
What is the One Piece?
Will it be a weapon powerful enough to reshape the world?
A lost piece of history that exposes the truth about the Void Century?
A treasure left by Joy Boy that fulfills the dreams of pirates everywhere?
Or something completely unexpected that only Eiichiro Oda could imagine?
Whatever the answer is, one thing is certain.
The moment Luffy and his crew reach Laugh Tale will be one of the most important moments in anime history.
Are You Ready for the End of the Journey?
For millions of fans around the world, One Piece is more than just a story. It is a journey that has lasted years — sometimes even a lifetime.
Readers who started the series as children are now adults. New generations continue to discover the adventure of the Straw Hat Pirates every day.
And the final destination is finally coming into view.
Somewhere at the end of the Grand Line lies the treasure that Gol D. Roger left behind.
The treasure that made him laugh.
The treasure that could change the entire world.
The One Piece.
