About OnePieceGuide
Who built this
OnePieceGuide is an independent fan project. I built it because I've watched One Piece for years and got tired of jumping between half a dozen sites every time I wanted to check whether the next episode was filler, or where a specific arc fell in the timeline. I wanted one place that just gave me the answer.
This site is run by one person, not a company. There are no investors and no editorial team. If something here is wrong, it's because I missed it — and you can tell me about it.
What this site does
OnePieceGuide breaks down all 1,160+ episodes of the One Piece anime into clear categories so you can decide what to watch and what to skip:
- Manga canon — about 1,002 episodes that adapt Eiichiro Oda's manga directly. The story you're meant to follow.
- Filler — 94 episodes (roughly 8.1%) of anime-original side stories. Some are skippable, a few are cult favorites.
- Mixed canon and anime canon — episodes that blend canon material with original content, or are wholly anime-original but woven into the main timeline.
Across 51 arcs and 10 sagas, you'll find which type each episode is, which arcs are pure filler, and where everything fits in the broader story.
How the data is sourced
The episode list is built by cross-referencing two sources: the Fandom Wiki's List of Anime Episodes (community-maintained, reasonably complete), and animefillerlist.com's filler classifications, which I check episode by episode for any disagreements. When the two disagree, I rewatch the episode and make the call myself. The first 50 episodes and the most recent 20 have been hand-verified.
The site updates weekly. New Elbaph Arc episodes are added to the database the same week they air in Japan.
A note about accuracy
I'm one person, not a team. If you spot a mistake — a wrong filler tag, a broken link, an arc description that misses something — please email me with the episode number and what's off. Reader corrections are how the data gets better.
