Ninjutsu

Ninjutsu (忍術; [ɲiꜜɲ.dʑɯ.tsɯ]), shinobi no jutsu (忍びの術; [ɕi.no.bʲi no dʑɯ.tsɯꜜ]) and ninpō (忍法; [ɲiꜜm.poː]) are terms for the techniques and skills used by spies and scouts in pre-modern Japan known as ninja. Some of these techniques are recorded in ninja scrolls, some which have been published and translated. The study of these scrolls have changed the perception of ninja and ninjutsu.

While there are martial arts schools that claim to be modern styles of ninjutsu, the historical lineage of these styles only go as far back as the 1950s.
