Chapters and Volumes

Chapters are arranged by volume, with their appropriate volume titles and chapters listed underneath. Chapter and volume titles include Japanese text, romaji 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 208 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.

Dust Jacket
Each volume is released with a dust jacket, featuring the volume cover, spine, Author's Notes, and the publishing information. Each cover is different, commonly feature the volume title, the header, and image featuring Monkey D. Luffy and several other important characters that appear in the volume, and the author's name. The header and author's name on each volume is of different color.

Volume 50 has a different format of cover changes from the standard title, then picture synopsis, to a picture (of Nami), the title (that is surrounded in flames), and is then followed up with the pictures of Zoro, Luffy, and Brook. This change was likely done to commemorate the fiftieth volume of One Piece.

Inside covers
The actual volume has a somewhat different cover, titled "Inside Cover" which are usually a sepia version of the colored dust jacket. However there are some exceptions:
 * Volumes 15, 19, 21, 28, 38, and 52 have an image of Pandaman instead.
 * The covers for Volumes 21, 28, 71 and 77 covers were the same as the colored covers, but Pandaman replaced other characters. Pandaman can also be found on inside covers for volumes 69 and 72-76.
 * Volume 52 had not just Pandaman, but many other Easter Egg characters that have been mentioned in the SBS.
 * Volume 63's inside cover showed Otohime's grave and Shirahoshi inside Megalo's mouth with Luffy on top.

The inside back cover usually shows a sea chart. Starting from Volume 25, Oda has started drawing a small ongoing story on the inside back cover of Volumes that can barely be spotted using his Easter Egg characters. here there are also some exceptions:
 * Volume 17 has a very small image of Chopper peeking out (from the wrong side, as usual) the bottom corner on the left side.
 * Volumes 36-38 being blank due to Pandaman being eaten by a large fish.
 * Volume 56 instead has two drawings of Luffy in STRONG WORLD outfits, one on each side of the cover.
 * Volumes 62-64 being covered by the message of encouragement and a cover page printed across the page.

Illustrations
At the beginning of each volume there is a grayscale image of Monkey D. Luffy.

SBS
Starting Volume 4, an Q&A section titled "SBS" is published before some of the volume's chapters. Those question are usually answered directly by Oda, and are thus consider canon.

Chapters not yet published in volume format
The following chapters have appeared in Weekly Shōnen Jump but have yet to be reprinted in tankōbon format, as collected volumes of One Piece are generally released every two to three months.


 * 922. Beasts Pirates General: Kaido (百獣海賊団総督 カイドウ)
 * 923. Yonko Kaido vs. Luffy (四皇カイドウルフィ)

Covers

 * The covers of Volumes 21, 42, 77, and 87 do not have Monkey D. Luffy on the cover as other volume covers, instead showing the antagonist group of a particular arc (Baroque Works, Cipher Pol 9, Donquixote Pirates, and Big Mom Pirates respectively) with the Straw Hats and their allies appearing on the following cover.
 * There have been thirty six unnamed characters so far, who have been appeared on the cover of a volume.
