In our Art, we use the term Ninjitsu for two reasons. First, because Grand Master Saito stated that the Clan never claimed to be "Ninja" (meaning his family were not assassins or government spies) a term that, historically, was never used by the Shinobi when referring to themselves. However there is a stereotype often connected with the term Ninja and he did not want such an association. Master Saito said this art was not for "assassins" but for the preservation of life.

Second, there are the definitions of the words themselves. One must first understand there is a difference in what one "hears" from what is actually written when working with the Japanese language.

Ninjutsu is the "literal" pronunciation of the kanji used to identify the "Ninja's" art. However, it is commonly accepted that Ninjitsu is merely the romanized or English interpretation/pronunciation of this same kanji. When examining the word/kanji ninjutsu the upper radical is represented by the combination of the two kanji: ha meaning sword edge and kokoro meaning heart. These kanji form a word character which means: Nin/Shin or to endure, to persevere or to steal in (infiltrate) in addition to many other definitions depending on the usage. Jutsu means: way or method of doing (something). So the name implies the way of doing Ninja (to infiltrate enemy territory, to endure or to persevere). The term Ninjitsu (pronounced Nin-jeet-soo) is often represented by the same kanji as Ninjutsu and we use them interchangeably. However, we also use the kanji Nin () meaning Man and Jitsu () meaning truth/reality when referring to our art as a whole. This is the truth or reality of "man" as it applies to the human condition. Our's is the art of understanding human behavior - something Master Saito stated and maintained when he opened the art to the public in 1966. Ninjitsu, as we use it is even more closely attributed to the word Ninpo, a term we use as well, and who's meaning encompasses the entire spectrum of what are called the Ninja Arts. It is not just the physical and martial aspects that define the art. The art is also expressed as "the ultimate or eternal reality of perseverance" and is deeply rooted in Buddhist Philosophy. Ninjitsu, in our context, means composure under pressure and truth or reality as the art applies to the human condition. Ninjutsu is the vehicle we use to actualize this reality.
