Shonen Jump



Weekly Shonen Jump (週刊少年ジャンプ) is a weekly manga magazine published by Shueisha. It is responsible for serializing the One Piece manga - among many others - in its original, single-chapter form.

Having sold over 7.5 billion copies since its inception in 1968 (with weekly circulation exceeding 6.5 million at its height in the 1990s), Weekly Shonen Jump consistently ranks as the world's most popular comic-book anthology.

Format
As its title suggests, Weekly Shonen Jump primarily targets the shonen demographic of teenage and pre-teen boys, and trends toward series with majority-male casts and action-heavy plots (though recent polls have indicated several of its series, One Piece included, may actually have majority-female readerships). In addition to One Piece, it has launched some of Japan's most iconic manga, including KochiKame, Dragon Ball, JoJo's Bizarre Adventure, Rurouni Kenshin, Yu-Gi-Oh!, Naruto, Bleach, and Boku no Hero Academia.

The typical issue of Jump is between 450 and 500 pages long, and contains around twenty different installments of manga interspersed with editorial features, celebrity interviews, advertisements, and other promotional materials (often for anime or video games licensed off one of its manga series). However, its paper quality is often noted to be "yellowed" or otherwise inadequate, compared with both competing manga magazines and Jump's own tankobon volumes.

Every issue allows two or three different installments to print their first few pages in color; for One Piece, this usually manifests in the series' famed color spreads.

Organization
Jump famously reorganizes the order of its contents every week, following a combination of editor initiative and reader response. These are (imperfectly) reflected by each issue's table of contents: When charting the popularity of each series, fans typically focus solely on the ordering of the black-and-white features, disregarding the color features as editorial promotions.
 * One series will be the Cover Color (巻頭カラー) feature, allotted most (if not all) of the cover-art and printed in color for its first few pages. These are always placed ahead of every other series.
 * Two or three other series will be Center Color (センターカラー) features, and also printed in color for their first few pages. These may be placed anywhere after the Cover Color feature; in some cases, they may even be the last feature.
 * The remaining features will be printed in standard black-and-white.

Schedule and Numbering
Jump typically releases new issues on Mondays of each week, with semi-regular shifts to other days (most often preceding Saturdays) when the printing schedule is affected by "minor" holidays or other incidents. However, there are four "major" holidays whose corresponding weeks skip release entirely:
 * New Year's Day, usually corresponding to the first week in January
 * Golden Week, usually corresponding to the first week in May
 * Obon, usually corresponding to the second or third week in August
 * Christmas, usually corresponding to the last week in December

Issues are indexed by year, and each issue's cover billed with a number (which resets with every new year) and a specific date; the issue that published the first chapter of One Piece, for instance, is billed as 1997's Issue 34 - August 4. Note that these, much like the cover dates of American comics, are typically several weeks behind each issue's actual release date, with the "first" issue in any given year usually released in late November of the previous year.

Any issues released immediately before major-holiday weeks are billed as "double" issues (e.g. Issue 4-5). This is purely to help the indexing process, and does not in any way indicate extra material for the issue.

Featured Covers
As one of the most popular series in Jump, One Piece has been directly featured on a number of its covers, always illustrated by Eiichiro Oda. These cover illustrations are almost invariably reused as title-page illustrations in subsequent tankobon, and/or reproduced in the Color Walk collections.

Lead Covers
Jump typically makes One Piece its Cover Color feature between four and seven times per year). These issues also reproduce a portion of the cover-art - usually cropped to focus on Luffy's face - on the spine.

Ensemble Covers
Covers that feature One Piece characters with other heroes from the magazine.

Related Titles
Due to its popularity, Weekly Jump has accrued a number of offshoot titles over the years. Most of these are completely irrelevant to One Piece, but several were responsible for publishing Eiichiro Oda's pre-One Piece one-shots, most prominently the later-canonized Monsters.

Trivia

 * To commemorate the series 20th anniversary being published in Shonen Jump magazine, the 33rd issue of the 2017 (that was released on the anniversary) used the same Luffy from the 34th issue of 1997 (that Chapter 1 was released on).
 * Some manga chapters that were released in the 2017 33rd issue had a Straw Hat featured somewhere in its story.
 * To commemorate the magazine 50th year of publication, the Shonen Jump logo was featured in every manga chapter released on the 34th issue of 2018.
