Manga Time Jumbo(まんがタイムジャンボManga Taimu Janbo) is a Japanese monthly yonkoma manga magazine published by Hōbunsha since April 1995. The magazine was published in the 1990s as Manga Time Zōkan. Before the May 2005 issue, the magazine was released on the 12th day of the month, but is now released monthly on the 4th. Manga Time Jumbo is printed as B5 size. Manga Time Jumbo had a "renewal" of sorts when it picked up series dropped by Manga Time Pop when it ceased publication in December 2003. The magazine's main draw, however, is due to its serialization of new works.
