What is Juju? Juju is a West African term pertaining to some form of magical power coming from an object. It may also refer to the magical object itself which is venerated with so much superstition. This object is typically used as an amulet or a fetish by some tribes in the western African region.
Jujutsu developed to combat the samurai of feudal Japan as a method for defeating an armed and armored opponent in which one uses no weapon, or only a short weapon.ujutsu, the current standard spelling, is derived using the Hepburn romanization system. Before the first half of the 20th century, however, jiu-jitsu and then jujitsu were preferred, even though the romanization of the second kanji as jitsu is unfaithful to the standard Japanese pronunciation.
