Ninjutsu sometimes used interchangeably with the term ninpō, is the martial arts practiced by the shinobi (also commonly known (outside of Japan) as the ninja).
The main character nin is composed of two lesser characters, the upper meaning “blade”, the lower meaning “heart” or “spirit”. Together they mean “stealth” and “secretness,” as well as “endurance” and “perseverance”. Jutsu means “true”, “technique”. Pō meaning “knowledge”, “principle” when found with the prefix “nin” carries the meaning of ninja arts, higher order of ninjutsu. Although the popular view is that ninjutsu is the art of secrecy or stealth, actual practitioners consider it to mean the art of enduring - enduring all of life's hardships.
