Chapters and Volumes

This is a list of all current volumes of the Japanese manga series One Piece, as well as the titles of the chapters contained therein. Chapters are arranged by volume, with their appropriate volume titles and chapters listed underneath. Chapter and volume titles include Japanese text, rōmaji transcription, and English translation of each title, along with the titles assigned by VIZ Media in its English adaptation.

Background
One Piece is published as a serial in the manga anthology magazine, Weekly Shonen Jump. As the magazine's name suggests, a new issue of Jump (and thus a new chapter of One Piece) is released on a weekly basis. Factoring in double issues of the magazine and personal hiatuses taken by Eiichiro Oda, however, approximately 45-48 chapters are published per year. Three to four months after appearing in Jump, these chapters are then compiled into collected volumes, or tankōbon, which contain between 9 to 11 chapters each and run to approximately 200 pages. These volumes also include new cover artwork, storyboard-phase sketches, a question-and-answer column by the author, a section where the character Usopp comments on reader-submitted fan art, and other bonus features. However, due to the economical limitations of the tankōbon format, any art originally printed in color (other than on the dust jacket) is reproduced in grayscale.

Chapters not yet in tankōbon format
The following chapters have appeared in Weekly Shōnen Jump (or will within the week, as titles are sometimes leaked by intrepid purchasers or subscribers ahead of the official Monday release). They have yet to be reprinted in tankōbon format, as collected volumes of One Piece are generally released every two to three months. Weekly chapters do come with some benefits, such as occasional cover illustrations or color title pages, and supplemental materials such as story information or character popularity polls. However, print quality (in terms of both paper and ink) is considerably lower than the collected releases, and artwork can be obscured by ads and other text placed there by the magazine. Buying the magazine on a consistent basis is also far more expensive than waiting for the book-format release.
