A year ago, we used mathematics to predict the date and number of the last One Piece chapter based on Eiichiro Oda’s predictions. This week the author estimated finishing the series in 5 years, so we decided to update the numbers.
Contrary to what most people may think, Oda is relatively consistent with its predictions. Of the 7 we know, 5 estimated dates are within a year. Obviously we don’t expect to hit the exact values through math alone, but these calculations are always fun to do, so here are the results for anyone interested.

One Piece Ending Based on Chapter
The next table lists information in which chapter and date One Piece will end, assuming that the predictions was based on chapters. “Real Average” includes all values, and “Tuned Average” excludes the two most distant predictions (by under and over).
One Piece Ending Based on Date
The next table lists information in which chapter and date One Piece will end, assuming that the predictions was based on date. “Real Average” includes all values, and “Tuned Average” excludes the two most distant predictions (by under and over).
One Piece Ending Average
The next table lists information in which chapter and date One Piece will end, calculated by averaging the estimations by date and chapters. “Real Average” includes all values, and “Tuned Average” excludes the two most distant predictions (by under and over).
Taking into account the data presented by the observed predictions, and excluding the two most distant predictions, it is estimated that One Piece will end on Monday, February 5, 2024 at chapter 1,140.
