Watching the entire One Piece anime series, which currently has about 1,126 episodes as of April 2025, would take a significant amount of time due to its length. Each episode typically runs around 22 to 24 minutes.
- If you were to watch all 1,126 episodes back-to-back without breaks, it would take over 411 hours, or roughly 17 continuous days of viewing
- Considering a more realistic schedule, such as watching 8 hours per day (similar to a full workday), it would take approximately 51 days to watch the entire series from start to the latest episodes
- Including the 15 One Piece movies adds additional viewing time, bringing the total to about 471 hours or nearly 20 days of continuous watching
- If you skip opening and ending themes and exclude filler episodes, the total watch time can be reduced somewhat, but it still amounts to around 15 to 19 days of nonstop viewing depending on the approach
In summary, watching all of One Piece is a major time commitment, requiring over 400 hours or more than two weeks of continuous watching, and realistically around one to two months if watching several hours daily
