Shurikenjutsu

Shurikenjutsu (手裏剣術) is a general term describing the traditional Japanese martial arts of throwing shuriken, which are small, hand-held weapons used primarily by the Samurai in feudal Japan, such as metal spikes bō shuriken, circular plates of metal known as hira shuriken, and knives (tantō).

Shurikenjutsu was usually taught among the sogo-bugei, or comprehensive martial arts systems of Japan, as a supplemental art to those more commonly practiced such as kenjutsu, sojutsu, bōjutsu and battlefield grappling kumi-uchi (old form jujutsu), and is much less prevalent today than it was in the feudal era.
