To celebrate reaching 600 million copies sold worldwide, One Piece creator Eichiro Oda recently gained widespread attention after sharing a video in which he revealed the 30-year-old secret behind the beloved anime and manga’s treasure, written on a piece of paper.

Oda has done an incredible job of guarding what lies inside One Piece for three decades. Yet, fans eager to uncover the mystery will need to embark on a lengthy voyage, as the legendary artist tore the paper in half, sealed it inside a locked treasure chest, and cast it into the sea on February 12.

The video opens with Oda seated in a dimly lit room, accompanied by subtitles asking, “What is the One Piece?” It then states, “That answer has been kept in the mind of creator Eichiro Oda. Now, finally, it has been written down on paper. Until the entire story is unveiled, the truth will remain beyond everyone’s reach at the ocean’s bottom. The One Piece Does Exist.”

The story of One Piece follows Monkey D. Luffy, whose goal is to become the Pirate King and discover the One Piece—a treasure hidden by the former Pirate King, Gold D. Roger. Roger was executed in his hometown by the Marines after surrendering to his terminal illness. The one who finds the treasure will become the true successor to Gold D. Roger.

Both the manga and its anime adaptation have garnered immense love for their compelling narratives centered on friendship, geopolitics, and life challenges.

Debates have recently swirled among fans about whether Oda has lost track of what the “One Piece” treasure truly is. However, the creator proved everyone wrong with this new viral stunt, demonstrating that he’s been in on the secret all along.
