The home of the International Modern Ninjutsu Federation, founded by Headmaster, Will Maier. NOTE:

Headmaster Will Maier developed "Modern Ninjutsu" based on his nearly 50 years experience in the martial arts. His style is an eclectic, innovative and efficient system of personal and family self-defense that is easy to learn and allows you to escape, or defeat an assailant, in many cases, in as little as 3 moves!

“Train for the reaction, not just the technique.”

In our Modern Ninja method, the first step in realistic self-defense is Awareness—the “A” in our A.C.T.S. model: Aware, Clear, Target, Survey.

Awareness means recognizing an attacker’s pre-fight signals—the physical and verbal “tells” that often reveal an imminent attack. We teach the acronym C.A.L.L. to identify four of the most common:

C – They Close the distance
A – They Angle off to one side
L – They Look away to distract before striking
L – They move one Leg forward to punch or back to kick

Failing to recognize these cues is how people get sucker punched, kicked, or stabbed. These are just a few of the warning signs, and there are many more that deserve attention.

But true Awareness goes beyond spotting the attack—it also means anticipating the attacker’s likely reactions when you begin your defense.

This is where much martial arts training falls short.

When practicing strikes, throws, joint locks, or any defensive skill, you must always consider the attacker’s options. In a real confrontation, an attacker will not stand still and allow a technique to happen without resistance. If your training ignores that reality, it becomes little more than role-playing—not functional self-defense.

For example, it is not enough to practice an outside wrist twist—omote gyaku in Ninjutsu or kote gaeshi in Jujutsu. You must also train for the attacker’s possible counters or escapes, and your responses to those reactions.

That level of awareness is what separates martial technique from real self-defense.
