The One Piece Fan Letter Series, released on October 20, is sparking interest among fans of the long-running anime, One Piece. Many are questioning whether this new addition is canon or simply a filler. The idea of ​​filler suggests that fans can skip it without missing essential plot points, but for those following the series, it’s important to understand its place in the One Piece world.
So, is One Piece fan letter canon? Yes. According to official sources, One Piece Fan Letter is a canon spin-off series. Canon stories in anime generally refer to stories that are derived directly from the original source material – in this case, the manga and related works of One Piece. One Piece Fan Letter is adapted from Straw Hat Stories, a spin-off novel approved by One Piece creator Eiichiro Oda. This approval confirms its place in the broader narrative, unlike filler episodes that are typically produced only for the anime.
Due to the anime’s hiatus until April 2025, many assumed that the series could be a filler that could be dropped without losing any main plot points. But One Piece fan letters provide a unique perspective. It focuses on the everyday lives of the Straw Hat crew from the perspective of regular people, particularly a girl who admires Nami, rather than the usual in-depth exploration of One Piece. This unique angle offers fans a closer look at the crew’s life beyond their main journey, making it both canon and unique to the One Piece story.
As the One Piece anime celebrates its 25th anniversary, One Piece Fan Letter explores new stories that have never been animated before. Although these stories do not directly impact the main plot, they provide insight into the characters, enhancing the series’ interest in dedicated fans.
Overall, One Piece Fan Letter is canon, not filler, and a thoughtful addition to the world of One Piece. For those invested in the Straw Hats and curious about new stories approved by Oda himself, this is a worthwhile series to check out, adding depth to the legendary saga of One Piece.
