Modern Ninjutsu

“The Art of Strategy” — Sun Tzu, c. 100 BCE

“Those who are victorious plan effectively and change decisively. They are like a great river that maintains its course but adjusts its flow… They are skilled in both planning and adapting… for they win in advance.”

I haven’t posted on Facebook for a while. Senior Master Instructor Chris Oliver and I have been busy working on the 25th Anniversary Edition of Secrets of Modern Ninjutsu, while I’ve also been preparing for my upcoming trip to Australia, Tasmania, and New Zealand. Moving forward, I plan to post here more regularly.

Today’s Sun Tzu quote connects directly with something I wrote about on April 19:

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

When you apply a strike, joint lock, takedown, or throw, knowing the technique itself is only the beginning. You must also understand how an attacker may react, resist, escape, or counter—and be prepared to adapt immediately.

That is a higher level of martial skill.

Like Sun Tzu’s river, your technique must have direction and purpose without becoming rigid. You must be able to “adjust the flow” in real time.

This is why Awareness—the “A” in the A.C.T.S. model I teach—is so important. Every technique can be countered. The skilled practitioner recognizes the opponent’s most likely options before they happen and is already prepared for the next response.

Ask yourself:

Do you know how someone could escape my wrist lock? Counter
my arm bar? Resist my throw? Block or evade my punch or kick?

And, more importantly, do you know what you will do next?

True self-defense skill is not simply performing techniques correctly. It is learning to anticipate reactions, adapt without hesitation, and remain one step ahead.

That is what Sun Tzu meant by “winning in advance.”

Don’t simply train the technique. Train what happens next.

Contemplate this deeply.

“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.

defense defense; self defense.

Martial Arts vs Real Fights

Why Your Kata Won’t Save You.
In countless dojos and gyms across the world, practitioners dedicate hours to kata. These are formal patterns of movement that express martial principles and showcase discipline. But let me be blunt: in a real fight, your kata will not save you.

That’s not a slight against tradition. Kata has historical value. It’s a cultural artifact, a tool for developing muscle memory and understanding core movements. But there’s a dangerous misconception at play, that mastering kata means you’re ready for combat. And, most unfortunately, you’re not...

The Disconnect Between Ritual and Reality
In a violent encounter, there is no clean line of attack. There are no respectful bows, no time to find your stance. Real fights are ugly, fast, chaotic, and unpredictable. They don’t follow a script… they just explode, usually without clear warning.

If your training doesn’t simulate that chaos — if it doesn’t teach you to recognize pre-fight cues, handle adrenaline, and to fight when your body is trembling with fear — then you’re preparing for a fantasy, not the reality of a fight for your life...

What Happens in Real Fights That Kata Doesn’t Teach You
• The “Freeze” Response

Most people don’t immediately react to violence with aggression. They often freeze, if only for a few seconds. Kata doesn’t teach you how to break out of that frozen state under the pressure of sudden conflict.

• Environmental Chaos

A fight could happen on gravel, in a bathroom stall, or between car doors in a crowded parking lot. Did your training include uneven surfaces, low light, loose stones, rolling bottles underfoot, or confined spaces?

• Pain and Panic

When you get hit, and you will, it hurts. Kata doesn’t prepare you for the shock of a real strike to the face or how to move while injured.

• Unpredictable Behavior.

So What Should You Be Training Instead?
Pressure Testing:

— Drill your techniques under resistance. Spar with intensity. Use gear and go hard in short, focused bursts. Get used to discomfort. The attacker might not throw a textbook punch. They might rush, grab, bite, or go for a weapon. Real fights are messy, and they don’t follow the choreography of Hollywood or stage drama club performances.

Scenario Training:

— Practice real-life situations: carjackings, domestic assaults, crowd encounters. Use role-playing, stress inoculation, and environmental setups.

Stress Inoculation:

— Incorporate drills that raise your heart rate and simulate panic. Train to breathe, assess, and act under pressure — not just perform.— Practice real-life situations: carjackings, domestic assaults, crowd encounters. Use role-playing, stress inoculation, and environmental setups.

Functional Simplicity:

— Complex combinations break down in chaos. Refine gross motor movements you can use while panicked, winded, or disoriented.

Final Thought: Honor the Past, But Train for the Present
Don’t let any school mistakenly delude you into thinking that strict traditional training alone prepares you for real violence. Respect the roots, but evolve the branches.

Survival doesn’t care how clean your form is. The street doesn’t care how many years you’ve trained. It only cares whether you can function when everything goes wrong.

Real self-defense starts where fantasy ends. Train like your life, or that of someone who you love, depends on it… because one day, it might.
