ninjutsu Shinobi: Winds of the 34th Generation

Ninja is the on'yomi reading of the two kanji 忍者 used to write shinobi-no-mono (忍の者), which is the native Japanese word for people who practice ninjutsu (忍術, sometimes erroneously transliterated as ninjitsu). The term shinobi (historically sino₂bi₂ written with the Man'yōgana 志能備), has been traced as far back as the late 8th century to a poem to Ōtomo no Yakamochi. The underlying connotation of shinobi (忍) means "to steal away" and—by extension—"to forbear", hence its association with stealth and invisibility. Mono (者), likewise pronounced sha or ja) means a "person."
