Eiichiro Oda has done it again. He turned a deal into a super cool pirate story. To celebrate One Piece selling over 600 million copies worldwide Eiichiro Oda finally wrote down the secret of what One Piece is. Then he placed it in a treasure chest. Threw it into the ocean.
The answer that One Piece fans have been wondering about since 1997 is now locked away in a real treasure chest. It's 651 meters deep in a spot in the sea.
How It All Went Down
- With the release of Volume 114 "The God Valley Incident" on March 4 2026 One Piece crossed the 600 million copy milestone.
- Eiichiro Oda marked the moment in a special way with a video.
- In the video Eiichiro Oda sits at his desk. Writes down the secret of One Piece on a piece of paper.
- He tears the paper in half keeps one part safe and seals the other part in a locked chest.
- He places the chest in a glass ball that can withstand the ocean pressure.
- Then he works with ocean experts to drop it into the sea.
The video ends with Eiichiro Oda saying, "The One Piece does exist." Then it shows him working on One Piece again.
Why This Feels Right for One Piece
This stunt feels like One Piece. It's an adventure filled with mystery. Eiichiro Oda always said he planned the ending of One Piece from the start. Now he has made that promise real.
One Piece fans are already studying the video for clues. Some are guessing where the treasure chest is, like Suruga Bay in Japan. Others are joking about renting submarines to go on treasure hunts.
The genius of this stunt is that it keeps the magic of One Piece alive. There are no leaks or early reveals. The secret of One Piece stays safe until the end. Everyone will experience it together.
A Quick Look at the Man Behind the Epic
Eiichiro Oda is from Kumamoto Prefecture. When he was four he decided to draw manga to avoid a "job". He was inspired by Dragon Ball. Pirate tales like Vicky the Viking. He started One Piece in Weekly Shonen Jump on July 22 1997.
The story of One Piece is about Monkey D. Luffy. He's the captain of the Straw Hat Pirates. They sail the Grand Line chasing freedom, dreams and the ultimate treasure left by Gol D. Roger, the Pirate King.
Now with Volume 114 the end of One Piece is closer. Eiichiro Oda’s work has outsold writers like Tolstoy. One Piece is a phenomenon with anime, live-action on Netflix, movies and more.
This ocean drop is not hype. It's part of the spirit of One Piece. The treasure is real both in the story and under the waves. Until Eiichiro Oda says otherwise the greatest adventure is still the one we're on together chapter by chapter.
What do you think? Is the One Piece a thing, a concept or something crazy? Share your theories. The real answer might be waiting at the bottom of the sea. The fun is in the hunt, for One Piece.
