Shōninki

The Shōninki (Japanese 正 忍 記) is a medieval ninja document from Kishū province.

Written by Natori Masatake in 1681 it describes the espionage strategies of the shinobi from Kishū.

The Shōninki is divided into Preface (Jo), three scrolls (Shomaki, Chumaki, Gemaki) and an epilogue (Okusho).

[3] The first scroll addresses basic skills, such as disguise and concealment, housebreaking and information gathering.

The second part deals with defense against enemy spies, human nature, physiognomy, recognizing and eliciting the true intentions of people and laying false trails and clues.
