literally "the art of gunpowder" is the use of
firearms,
gunpowder and
especially by
ninja.
The history and mythology surrounding
ninjutsu and kayakujutsu are similar to the history of chemistry and the mythology surrounding
alchemy. Thus kayakujutsu mysticism refers to
elements like the Earth (Chi) to develop Fire (Kaji) just as alchemy referred to
elements just as air, earth, fire and water.
