Jump Square (Japanese: ジャンプスクエア, Hepburn: Janpu Sukuea), also written as Jump SQ. (ジャンプSQ.), is a Japanese monthly shōnenmanga magazine. Published by Shueisha, the magazine premiered on November 2, 2007, as a replacement for Monthly Shōnen Jump, another manga anthology that Shueisha discontinued in June of that year. The magazine is a part of the Jump line of magazines. The manga titles serialized in the magazine are also published in tankōbon volumes under the Jump Comics SQ. imprint. Shueisha reported that readers of Jump Square tend to range from 15 to 34 years of age.[2] The current (2015) editor-in-chief is Kôsuke Yahagi.[3]
When Jump Square was launched, the initial printing of 500,000 copies quickly sold out. Over 70% of the copies released across Japan sold within three days. Shueisha printed an additional 100,000 copies to help meet the demand, something normally not necessary with Japanese magazines.[6] The second issue also sold well, requiring a second printing of 60,000 copies.[7] After the first issue excitement died down, circulation leveled off in the vicinity of 370,000 copies and by 2015 had declined to 270,000, mirroring a general drop-off in circulation throughout the industry.[8]
Features
Jump Square's primary content is manga serials. In addition to the manga series, some issues include serialized light novel chapters from works published by the Jump j-Books label. One-shots from established manga writers are featured in a section of the magazine called the "Supreme Yomikiri Series" (SUPREME読切シリーズ, Supurīmu Yomikiri Shirīzu), while pieces from up-and-coming writers occasionally appear in the "Explosive Yomikiri Series" (Explosive読切シリーズ, Explosive Yomikiri Shirīzu) section.
Jump SQ.II (ジャンプSQ.II, Janpu Sukuea Sekando) short for Jump Square Second (ジャンプスクエアセカンド), is a spin-off issue of Jump SQ of which three volumes have currently been published, beginning on April 18, 2008.[9]
A contest organized by Shonen Jump (a monthly English version of Weekly Shōnen Jump) and Jump SQ., offered a Jump SQ II (Second) issue autographed by Lee and Takei to the random winner at the 2008 New York Comic Con.[13] Three regulars: Sekai no Chūshin de Taiyō ni Hoeru, Tsumikabatsu, and Mahō no Ryōri Chaos Kitchen; were put in the SQ II magazine as their own SQ II exclusive one-shot, along with other one-shot like Missing Battery, Cross, or Alone Again.[14]
The success of Ultimo led to the extra mini book named The Man Who Created "Spider-Man" and the "X-Men" - Stan Lee the book! (｢スパイダーマン｣｢X-MEN｣を作った男 スタン·リー the Book!, "Supaidāman", "Ekkusumen" o Tsukutta Otoko - Stan Lee the Book!) which is completely based on Lee's American comics, mostly Amazing Fantasy (first Spider-Man, Iron Man, and The Hulk).
