What Is Kosho? Beyond Style to Study

concepts learning philosophy Jul 14, 2025

When most people ask about Kosho Shorei Ryu, they expect to hear about techniques, forms, or fighting methods. They want to know what makes it different from karate, kung fu, or jujitsu. But asking "what is Kosho?" is like asking "what is education?" The answer isn't found in the curriculum. It's found in the process of learning itself.

Kosho isn't a martial art in the traditional sense. It's a study. A way of understanding yourself, your environment, and your relationship to both. While other systems teach you what to do, Kosho teaches you how to see. And once you learn to see clearly, what you do becomes less important than why you do it.

Beyond the Surface: Kempo as Philosophy

The word "Kempo" itself has been misunderstood for decades. Most practitioners think it refers to a fighting style that combines punches and kicks. But according to James Mitose, the 21st inheritor of this lineage and teacher of current Hanshi Bruce Juchnik, Kempo was never meant to be a style at all.

"Kempo is not a style," Mitose explained. "It is a philosophy first. Styles and systems are born from a philosophy and understanding of that philosophy."

This distinction changes everything. When you approach Kosho as a philosophy rather than a fighting system, you begin to understand that the physical techniques are simply tools for teaching deeper principles. The real study is learning to understand yourself so thoroughly that conflict dissolves before it begins.

Around 1235-1245 A.D., a Buddhist priest meditated beneath a pine tree and gained insight into humanity's relationship with nature and the process of existence. He understood how change drives growth and the importance of adapting to circumstances. This understanding became the foundation of what we call Kempo, not a collection of fighting techniques, but a method for studying the self and one's natural environment.

The Study vs. The Style

Most martial arts focus on creating fighters. Kosho focuses on creating students. The difference is profound.

When you study a traditional martial art, you learn a specific curriculum. You memorize forms, practice combinations, and work toward belt rankings. The goal is to master the system as it was taught to you. Progress is measured by how well you can replicate what came before.

When you study Kosho, you learn to question everything, including what you think you already know. You don't master the system. The system becomes a vehicle for mastering yourself. Progress is measured not by what you've accumulated, but by what you've understood.

This is why Kosho practitioners talk about "principled adaptation" rather than rigid technique. Principles don't change, but their application must adapt to circumstances. When you understand the principle behind a movement, you can apply it in countless ways. When you only know the technique, you're limited to one response.

James Mitose warned against collecting kata without understanding: "collecting kata without understanding is like repeating words in a language you never learned to speak. Movement should emerge from principle, not memory."

Environment as Teacher

In Kosho, everything is your teacher. Your training partner, the ground beneath your feet, your own emotional state, even your mistakes. This perspective transforms how you approach practice.

Most martial arts treat the dojo as a controlled environment where you perfect techniques before applying them in the "real world." Kosho treats every environment as a dojo. Your kitchen, your office, your car, they're all laboratories for studying balance, timing, and relationship.

This doesn't mean you're constantly preparing for physical conflict. It means you're constantly studying the principles that govern effective movement and clear thinking. How you handle stress at work reflects the same patterns as how you handle pressure in sparring. How you breathe during a difficult conversation uses the same awareness you need during close-quarters combat.

Your environment includes more than physical space. It encompasses your mindset, the mindsets of those around you, your emotional state, and your sense of well-being. Kosho teaches you to read all these factors simultaneously and respond appropriately.

Humility as Foundation

Perhaps the most important aspect of Kosho study is maintaining what Zen calls "beginner's mind." The moment you believe you've mastered something, you stop learning. The moment you stop learning, you start declining.

"Kempo is supposedly a humbling experience," notes the Okuden teachings. "It is an experience and process that should maintain a form of humbleness. This seems to be mankind's biggest problem when it comes to dealing with the martial arts. It is the lack of ability to remain humble."

This humility isn't about diminishing yourself. It's about maintaining curiosity. Every encounter, every training session, every moment of daily life becomes an opportunity to discover something new about yourself and how you relate to the world around you.

True Kosho practitioners are recognizable not by their physical prowess, but by their character. They are polite, dignified, and possess the qualities needed to help others. They understand that the real enemy isn't the person standing across from them, it's the reflection they see in the mirror.

The Living Tradition

One of the most beautiful aspects of Kosho is that it's designed to grow. Unlike systems that preserve ancient techniques exactly as they were taught centuries ago, Kosho expects each generation to deepen the understanding and adapt the expression.

When James Mitose came to Hawaii in 1936 and began teaching in 1942, he simplified the curriculum for wartime needs. American servicemen needed effective self-defense quickly, not years of philosophical study. This practical focus served its purpose, but it also created misconceptions about what Kempo really was.

Later, when Mitose had the opportunity to share the deeper aspects of the art with dedicated students like Bruce Juchnik, he revealed that the combat techniques were just the beginning. The real study involved understanding the principles behind the movement, the philosophy that shaped the techniques, and the character development that made the knowledge worth having.

This evolution continues today. Hanshi Juchnik has integrated insights from Filipino martial arts, Indonesian systems, and other traditions, not to create a new style, but to deepen his understanding of the principles that underlie all effective movement. This is principled adaptation in action.

Beyond Fighting: The Complete Art

While self-defense remains an important component of Kosho training, it's only one aspect of a much larger study. Traditional Kosho curriculum included:

  • Energy Collection: Breathing, posture, and alignment training
  • Healing Arts: Shiatsu, nutrition, and herbology
  • Cultural Studies: Understanding the historical and philosophical context
  • Escape Arts: Movement, timing, and environmental awareness
  • Philosophy: Buddhist principles, meditation, and spiritual development

This comprehensive approach reflects the understanding that a complete martial artist must be a complete human being. You can't develop genuine skill in one area while ignoring others. Your physical technique reflects your mental state. Your character development affects your strategic thinking. Your breathing affects everything.

Making the Shift

If you're coming to Kosho from other martial arts, this perspective might feel uncomfortable at first. You might wonder when you'll learn "the techniques" or start "the real training." That discomfort is valuable information. It shows you're beginning to question assumptions you didn't know you had.

The shift from studying techniques to studying principles takes time. The shift from training for fighting to training for understanding takes even longer. But once you make this transition, you'll find that your martial arts training becomes infinitely richer and more applicable to your daily life.

You'll stop asking "What technique should I use?" and start asking "What does this situation require?" You'll stop trying to impose your will on circumstances and start learning to read what's actually happening. You'll stop fighting against resistance and start learning to blend with it.

The Never-Ending Path

Perhaps the most liberating aspect of Kosho study is the recognition that you'll never be finished. There's no final belt, no ultimate technique, no moment when you can declare yourself complete. This isn't a flaw in the system. It's the point.

As long as you're alive, you're changing. As long as you're changing, you're learning. As long as you're learning, you're growing. Kosho gives you a framework for that growth that can last a lifetime.

Every day brings new challenges, new relationships, new environments. Each one is an opportunity to apply what you've studied and discover what you haven't understood yet. The beginner who approaches training with curiosity and humility often progresses faster than the experienced practitioner who thinks they already know the answers.

"Remember that form is created from formlessness," taught James Mitose. "Formlessness is form and also form is formlessness if one understands form." This isn't mystical philosophy. It's practical instruction for staying flexible in your thinking while remaining grounded in sound principles.

Your Study Begins Now

If this perspective resonates with you, you're ready to begin genuine Kosho study. Not the study of techniques, though you'll learn plenty of those. Not the study of forms, though they're valuable tools. The study of yourself and how you relate to everything around you.

This study doesn't require a uniform, a rank, or even a formal school. It requires honesty, curiosity, and the willingness to question what you think you know. It requires the courage to see yourself clearly and the discipline to change what needs changing.

Whether you're a complete beginner or an experienced martial artist, whether you're interested in self-defense or personal development, Kosho offers a path for deepening your understanding. The question isn't whether you're ready for Kosho. The question is whether you're ready to study.

The journey begins with a single step: looking in the mirror and acknowledging that the person staring back at you has more to learn than they could possibly imagine. And that's exactly where the real training starts.
