The ninjatō (忍者刀), ninjaken (忍者剣), or shinobigatana (忍刀), are allegedly the preferred weapon that the shinobi of feudal Japan carried. It is portrayed by modern ninjutsu practitioners as the weapon of the ninja, and is prominently featured in popular culture. Replicas of this sword are displayed at the Ninja Museum of Igaryu, established in the mid-1960s.
