Ninja Workshop

Ninja, also knows as Shinobi was a secret agent, spy and mercenary in feudal Japan. The functions of a ninja included espionage, deception, and surprise attacks. Their covert methods of waging irregular warfare were deemed dishonourable and beneath the honour of the samurai. 

Ninja figured prominently in legend and folklore, where they were associated with legendary abilities such as invisibility, walking on water and control over natural elements. As a consequence, their perception in popular culture is based more on such legends and folklore than on the covert actors of the Sengoku period.
