At its heart, Kyo-Jitsu Ryu, or the “School of Passive Resistance,” is an American personal safety system developed by Sensei B. Duncan. While its principles are defined in our glossary, this article delves deeper. It’s a modern approach designed for today’s world, acknowledging that threats aren’t just physical—they can be psychological and emotional, too.
“To injure an opponent is to injure yourself. To control aggression without inflicting injury is the Art of Peace.”
— Morihei Ueshiba, Founder of Aikido

A Multi-Disciplinary Foundation
Kyo-Jitsu Ryu is not a collection of arbitrary techniques; it is a system built on a deep understanding of scientific and philosophical principles. This multi-disciplinary foundation is what makes it so adaptable and effective.
The Scientific Core: Physics, Biomechanics, and Psychology
At its core, the art is an application of science. Principles from Newtonian and Lagrangian physics inform how to manage momentum, leverage, and force. Biomechanics provides the blueprint for understanding how the body moves, its strengths, its weaknesses, and how to disrupt its structure with minimal effort. Furthermore, psychology is woven into every aspect, from managing one’s own fear response to understanding an opponent’s intentions and de-escalating conflict.
The Philosophical Framework: A Guide for Practical Application
While science explains how the system works, philosophy explains why it is used and provides a moral and ethical compass. The physical and psychological training is designed to enhance a student’s effectiveness and social acceptability in any situation. This is achieved through deep questioning and a unique interpretation of natural concepts.
For instance, students contemplate the Zen koan, “What is the sound of one hand clapping?” The goal is not a literal answer, but the realization that conflict, like a clap, requires a minimum of two participants. This insight is the foundation of de-escalation and strategic non-engagement.
Similarly, the system’s use of natural elements goes beyond common metaphors:
- Earth: This represents the immovable stability of our emotional and psychological state. It is the “rock solid” belief that everyone has the right to be wrong, which keeps us grounded in reality, not distorted by our own expectations.
- Air: This is about persistence and initiation. Air continues on its path despite obstacles. It also remains still until acted upon. We use the image of a fly entering a sealed, stale room; its movement circulates and refreshes the entire environment, teaching that a single, intentional action can change everything.
- Water: Beyond fluidity, water represents resilience. It is the only compound that maintains its core properties whether solid, liquid, or gas. This reminds us to maintain our principles regardless of the situation, demonstrating that situational ethics is an illusion.
- Fire: Rather than just destruction, fire represents the drive for constant improvement. It always moves forward toward a fuel source, never waiting. This symbolizes our own minds, which should always be hungry and actively seeking new knowledge and growth.
Who Can Benefit from This System?
Because Kyo-Jitsu Ryu is an educational discipline, not a sport, its principles are valuable to a wide range of individuals:
- For the Everyday Citizen: It provides the awareness and de-escalation skills to navigate public spaces with more confidence and safety.
- For Professionals (e.g., healthcare, security): It offers a systematic approach to managing conflict and ensuring personal safety in high-stress environments.
- For Existing Martial Artists: It serves as a powerful philosophical and strategic “operating system” that can enhance the effectiveness of any physical art.
- For Students: It teaches invaluable life skills in critical thinking, emotional regulation, and self-reliance.
Rigorously Tested, Practically Applied
A system is only as good as its applicability in the real world. Kyo-Jitsu Ryu’s principles have been rigorously tested and proven effective across three distinct arenas of conflict:
- In the Ring: The controlled environment of sport competition allows for the testing of techniques against a resisting opponent under a specific ruleset.
- In High-Stakes Environments: The founder’s direct experience applying these principles in military contexts, including during Operation Desert Storm, has been instrumental in refining the system for maximum effectiveness under pressure.
- On the Street: The ultimate test is the unpredictable nature of a real-world self-defense scenario. The system’s focus on awareness, de-escalation, and simple, effective principles makes it uniquely suited for these chaotic situations.
This commitment to practicality continues in training. Higher-level students (brown and black belts) are subject to sudden, random, and unexpected “mini-attacks” from instructors. These controlled tests are not intended to cause harm, but to keep judgment sharp and ensure that techniques remain reflexive, effective, and grounded in reality.
The Primary Objective: Personal Safety
The primary goal of Kyo-Jitsu Ryu is not to “win” a fight. The objective is far simpler and more practical: to get home safely. This focus on de-escalation is not just a martial arts philosophy; it’s a proven strategy supported by conflict management professionals for managing difficult situations safely. The art is about restoring a sense of peace and safety on three levels: physical, psychological, and philosophical.
The Core Principle: Control from Within the Self
The cornerstone of Kyo-Jitsu Ryu is “Control from within the Self.” This is about gaining maximum influence over your environment by first mastering yourself—having conscious control over what you think, say, and do.
We believe that choice is the basis of response, while reaction is a dangerous reflex. Think of being cut off in traffic. The reaction is anger. The response is to breathe, check your surroundings, and create space. A response is intentional and powerful. The first lesson of Kyo-Jitsu Ryu is dedicated to building this ability.
The Path from Reaction to Powerful Response
Impulsive, Emotional, Uncontrolled
Identify the feeling without judgment.
Take a deep breath to create space.
Select an intentional action.
Implement your chosen response.
Intentional, Strategic, In Control
The Role of Shiatsu in Understanding Biomechanics
The ability to generate power without size lies in Kyo-Jitsu Ryu’s unique foundation: the healing art of Shiatsu. To understand how to heal the body, one must first understand how it works—its balance, vulnerabilities, and structure. This same knowledge is the key to protecting the body and disrupting an attacker’s balance with minimal force.
This deep understanding of the body is the foundation for the core physical concept of “relaxed tension.” The term may sound like a contradiction, but it describes a precise physical state between being completely limp and being rigidly tense. The ‘tension’ comes from maintaining a solid, connected body structure, while the ‘relaxation’ comes from releasing all unnecessary muscular effort. Think of a cat at rest—it is completely soft, yet it can explode into action instantly. This state allows for maximum speed and efficiency, generating power without telegraphing movement, which is the key to overcoming a strength disadvantage.
What to Expect in Your First Class
Starting something new can be intimidating, but a first class is not about fighting. It’s about learning in a safe, supportive environment. The focus is on foundational skills like:
- Choice Recognition Training (Psychological): We work to separate fact from fiction in our beliefs to enable us to learn to make decisive, intentional choices. This is the beginning of control.
- Building a Solid, but Adaptive Structure (Physical): How to remain grounded and balanced while maintaining the freedom of movement in all limbs.
- Learning the “Control Yourself or Something/Someone Else Will” perspective (Philosophical): This teaches us not only self control, but also accountability. This is less about personal restrictions than acknowledging that nothing happens TO us without our permission and recognizing that we are the masters of our own destiny.

Common Questions & Honest Answers (FAQ)
1. Isn’t “passive resistance” just letting someone walk all over you?
Not at all. It’s a strategic choice. “Passive resistance” means you are not the aggressor. It does not mean you are a passive victim. It means you use awareness, de-escalation, and positioning to avoid a physical conflict if possible. If a situation turns physical, the response is decisive, efficient, and focused entirely on creating an opportunity to get to safety, not on “winning a fight.”
2. This sounds very philosophical. Will it work in a real, violent attack?
Yes. The philosophy is the foundation for the physical practice. In a high-stress situation, complex motor skills fail. Because Kyo-Jitsu Ryu is based on simple, natural body movements and principles—not complicated techniques—it is more reliable under pressure. The mental training to stay calm and responsive is just as important as any physical move.
3. Why not just learn a more aggressive art like Krav Maga or MMA?
Combat systems like Krav Maga and MMA are highly effective tools for a specific goal: incapacitating an opponent in a physical fight. Kyo-Jitsu Ryu operates on a broader spectrum of conflict. It is a comprehensive personal safety discipline where the physical confrontation is seen as a last resort, not the starting point. The system provides the tools to manage the entire timeline of a potential conflict—from situational awareness and verbal de-escalation to physical defense—with the consistent goal of creating safety, not necessarily winning a fight.
4. How long does it take to learn? I need to feel safer now.
You can learn valuable and practical safety skills in your very first class. The focus on awareness and distance management provides an immediate benefit. While true mastery is a lifelong journey, the core principles of Kyo-Jitsu Ryu are designed to be applied immediately to make you safer today.
5. I’m not big or strong. How can this work against a much larger attacker?
This is the core strength of Kyo-Jitsu Ryu. Instead of focusing on matching strength, the system teaches you how the human body is designed to move—and more importantly, how it isn’t. By understanding the body’s natural mechanics, you learn to use leverage and structure, not muscle, to disrupt an attacker’s balance and stability. The goal isn’t to fight their strength but to guide their body into positions where their strength is irrelevant. This knowledge, applied with the principle of creating safety rather than causing injury, is where true power lies. It makes size and strength much less of a factor.
6. Why is there so much focus on science and philosophy instead of just learning physical techniques?
Because in a real-world situation, your mindset and understanding determine the effectiveness of any technique. Simply memorizing moves is insufficient. The science (physics, biomechanics) explains why a technique works, allowing you to adapt it to any situation. The philosophy provides the ethical framework for when and if a technique should be used. This multi-disciplinary approach ensures you are not just a collection of reflexes, but a capable, thinking individual who can make sound decisions under pressure.
Ultimately, Kyo-Jitsu Ryu is more than a set of techniques; it is an educational discipline for conflict management. It provides a comprehensive framework—grounded in science, guided by philosophy, and proven by practical application—for navigating the world with heightened awareness, confidence, and calm.
