Ninjutsu (Way of the Ninja or Ninja Way) is often translated to “the art of stealth” or “the art of invisibility”; ninjutsu can also mean "the skill of going unperceived". Ninjutsu is not a martial art system, as it is most commonly mis‐portrayed. Ninjutsu is a separate and self‐sufficient art of warfare.

In the Sengoku period, they were referred to by a variety of names, but not "Ninja". "Ninja" is an Edo period term. The two characters, "Nin" and "Ja" are the same characaters as "Shinobi" and "mono". One of the original terms was "Shinobo no mono"--literally, person of stealth. Prior to the Edo period, the word "Ninja" was not used. Shinobi, or Shinobi no mono, was one term. "Kusa" was a very common term also, used to denote stealthy scouts. 

Some have “created” new systems based off the historical evidence of ninjutsu, in turn employing a system that meets a modern world; these are typically referred to as neo‐ninja’s or neo‐ninjutsu.

Remember, ninjutsu is not so much one particular approach to martial arts, but a collection of fundamental survivalist techniques that came out of necessity in a politically volatile Japan; now modified for today's practitioners. Knowing this, it is reasonable to see similarity between systems as well as the uniqueness that each system portrays. Remember there is no one definition of what a ninjutsu system must include; there is no governing ninjutsu body. Only the ethics and principals of each system determine the authenticity of that system.  

Definition: Neo-Ninja/ Neo-Ninjutsu

A 20th-century revival of interest in the culture of the shinobi/ninja of Japan.

Neo-Ninja’s have no direct, genuine or provable lineage to Japanese ninjutsu, but practice according as they appreciate  those philosophies. Neo-Ninjutsu is not so much a martial art as it is a philosophy of practice surrounding the “art of stealth” and the philosophy of the ancient shinobi.

Neo-Ninjutsu organizations cover a wide spectrum of belief and ideals regarding their training.

Being a Neo-Ninja does not make their training any less  or more authentic then those who believe they are of “authentic Ninja lineage”.
