was a shà Ânen manga magazine which was published monthly in Japan by Shueisha from 1970 to 2007 under the Jump line of magazines. It was the sister magazine to Weekly Shà Ânen Jump.
The Monthly Shà Ânen Jump magazine started as a spin-off issue of Weekly Jump called Bessatsu Shà Ânen Jump.
The second spin-off issue was called Monthly Shà Ânen Jump, which caught on and became its own separate independent manga magazine.
Shà Ânen manga magazines in Japan in the 1980s focused on bishà Âjo characters, and Monthly Shà Ânen Jump stood out due to the many product and toy tie-ins it had during that period and into the 1990s. An off-shoot, Hobby's Jump, was published for 16 issues from 1983 to 1988. Another spin-off Go!Go! Jump was a collaboration between its sister magazine Weekly Jump and Monthly Jump; it was published in 2005 and was only published once.
On 22 February 2007, Shueisha announced that Monthly Jump would cease publication as of the July issue (on sale June 6, 2007). Sales had slumped to a third of the magazine's peak, though a new magazine called Jump SQ. took its place on 2 November.
In a letter dated 2 May 2007, Shueisha announced that Claymore would take a month break but it, Gag Manga Biyori, Rosario + Vampire, and Tegami Bachi would be continued in Weekly Shà Ânen Jump until the start of the magazine Jump SQ.
Titles with â were transferred to Shueisha's Jump Square. The magazine's longest running manga were: Kattobi itto (Motoki Monma), Wataru Ga Pyun! (Tsuyoshi Nakaima) and Eleven (Taro Nami, Hiroshi Takahashi)
