For generations, these martial traditions have forged the human spirit into an orderly, unfettered, and powerful being—capable of decisive action in an ever-changing world.

Welcome to the online home of kenjutsu of the Ittō Tenshin-ryū (swordsmanship), Yamate-ryū Aikijutsu, and Goseki-ryū Aiki Heihō. These lineages preserve powerful teachings in conflict, strategy, and human performance—teachings that forge clarity under pressure, strengthen the will, and cultivate the capacity to meet conflict without hesitation in the moment it arises. Through this study, our deshi learn to live balanced, consequential lives and to experience the quiet joy that emerges from such a life.

Born in Japan, as familial martial traditions, Ittō Tenshin-ryū and Yamate-ryū arrived in the United States in 1968, where their transmission has continued without interruption. They have endured because they offer something rare: teachings of consequence, supported by the disciplines and techniques required to realize and apply them.

If you are asking what these arts offer, why they continue to matter, or how one begins such a study, this page provides the foundation. Here you will find a concise orientation to their purpose, relevance, and meaning—and what it entails to enter a dojo devoted to the responsible study of conflict and the pursuit of mastery.

Relevance in the Modern World

Although the cultural conditions that gave rise to these arts have changed, the teachings that address conflict, strategy, and human performance remain as relevant today as they were at their inception. Teachings that develop the human spirit are timeless.

Preserved Without Dilution

Their power endures because the teachings—and the methods used to realize them—have been preserved faithfully. They are further strengthened by the experience of our deshi, who apply these principles across diverse fields, including leadership, medicine, national security, police and military service, entrepreneurship, and other domains where conflict and consequence are real. Insights gained through this real-world application return to the traditions, refining and reinforcing their teachings. In this way, the traditions continue to grow while remaining true to their foundations.

We are not preserving something that once was; rather, we are advancing what is.

The Path of Development

An orderly, unfettered, and powerful human being rarely emerges without intention. Development requires discipline, sustained effort, and a willingness to confront one’s own limitations. When this pursuit is shared with others, a brotherhood forms, and moments of profound joy arise—like steam rising from freshly quenched iron.

These traditions do not merely transmit techniques; they shape those who train within them.

A Direct Inquiry into Conflict and Power

These arts are not a fanciful escape or a form of entertainment. They are a direct and present inquiry into conflict and reality. This is not to say that training is without joy, but rather to distinguish clearly the purpose of what we do.

From Bujutsu to Budo

The tangible skills and capacities cultivated through the science of these martial traditions (bujutsu) serve as a gateway to something deeper—a path (dō) toward the essence of reality itself. At its core, budō is a way of living grounded in the sustained study of a single subject—conflict—as a means of penetrating the essence of all things.

The decision to walk this deeper path is personal. Some deshi enter our traditions seeking only the bujutsu we teach, and this study alone is demanding, powerful, and transformative. Others choose to continue their inquiry, using the discipline of training to examine the nature of conflict, power, and reality itself. Both approaches are recognized and honored within our traditions.

Who Trains With Us

Among our ranks are captains of industry, medical professionals, government employees, police officers, warriors, teachers, and others drawn to the depth and integrity of these teachings. Their professions differ, but they share a common pursuit: to advance in life, to shoulder responsibility, and to grow in the company of others committed to the same demanding work.

Many did not begin their careers at this level. The traditions helped forge the qualities that now define them.

Training and the Dojo

Training does not occur in a “school” but in a dojo. Its purpose is not to accumulate techniques, but to realize a way of being. Instruction is structured, progressive, and appropriate for both beginners and senior students. You are not expected to arrive knowing anything. You are expected only to train sincerely.

At the heart of it all lies self-mastery.

Etiquette and Culture

Our traditions employ a distinctive etiquette rooted in Japanese culture. Its purpose is not formality for its own sake, but the creation of an environment in which violence and power can be studied responsibly. Etiquette is learned gradually and reinforced through training; no prior knowledge is required.

Benefits of Training

Training within our traditions develops:

• The capacity to face conflict without hesitation—to understand its nature and respond with clarity and decisive action.

• A strengthened will, forged by confronting internal resistance, fear, and uncertainty until they no longer govern your choices.

• Sharper perception and strategic insight, developed through steady inquiry into reality, power, and human behavior.

• A disciplined path of personal advancement, where lessons extend beyond technique and into the choices you make every day.

• A community of individuals pursuing the same demanding work, offering challenge, support, and shared purpose.

How Long Does It Take?

There is no single or correct timeline. For some, the lesson they seek appears quickly, and their path shifts. For others, the value lies in the long road—the fellowship of training and the lifelong pursuit of mastery. As one continues, the reasons for training evolve, shaped by new realizations.

The aim of these traditions is not to create followers, but to empower individuals to live lives of consequence, balance, and joy.

Beginning the study does not bind anyone to a lifelong commitment. Training starts with a period of acclimation, allowing new students to experience the rhythm of the traditions and determine whether this path is right for them—and allowing us to determine whether they are a good fit. Clarity emerges through practice.

First Steps on the Path

Your first steps may feel uncertain; this is natural and shared by all who have walked this path. You will be welcomed, supported, and guided through your acclimation period and beyond. The dojo is a challenging place—but never a lonely one.

How to Begin

Please review the traditions we offer and decide which one you would like to apply to train in. Many of our deshi study more than one art, but we require that you ground yourself in one before beginning another. Each tradition has a dedicated page, accessible via the navigation links located at the bottom of this page.

Next, visit our licensed dojo page to see if we have a dojo near you. Contact information for each dojo is available there. Reach out by email or through the dojo’s website, introduce yourself, and inquire about training.

While each dojo’s onboarding process may differ slightly, it usually consists of an introduction by email, arranging a time to visit the local dojo, observing a class, and an opportunity to meet with the instructor or a senior student to address any questions you may have.

Once you have applied to the dojo and have been accepted, you will be guided on uniform and weapons requirements and how to obtain them.

We welcome all who possess the hunger to learn and the spirit to sustain that desire.
