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).

A shuriken is a Japanese concealed weapon used by samurai or ninja or in martial arts as a hidden dagger or metsubushi to distract or misdirect.
