Why Learn Japanese Swordsmanship?

Japanese swordsmanship is a sophisticated art and martial science. Through swordsmanship, we learn the applied principles of strategy (heiho).

Japanese sword arts are also the foundation of traditional Japanese jujutsu. The movements in classical jujutsu come directly from kenjutsu (Japanese sword combat arts).

What Aiki-Jujutsu techniques will you teach me?

Every student’s initial study involves learning proper breathing, movement, relaxation, awareness, and falling. You will also learn strikes, throws, and how to use training weapons to augment your practice.

Most importantly, our goal is to teach you skills to become safer, more aware, and more capable of heading off conflict before it happens.

What are the principles of Aiki-Jujutsu

Our primary principles are, 1) Move, 2) Allow (Don't contest for space), and 3) Don't be where pressure or force is applied. There are many more strategic principles that you will learn over time through dedicated training.

What ages do you teach?

We accept students 14 years and older. Please contact us if you would like to discuss further.

I've never training in martial arts. Can I learn Nami ryu?

If you have the willingness to learn, we can teach you.

Are there competitions in Nami ryu?

Classical Japanese martial arts are, at their core, schools of military strategy. While this context continues to be the foundation of Nami Ryu principles and techniques, we are dedicated to teaching personal defense and the defense of loved ones. With this in mind, we do not have competitions or train with the mindset of competing for points. Competitions and tournaments can be beneficial on many levels, but they are not designed to address modern self-defense scenarios so they are not part of our training.

Rather, in accordance with Classical Japanese training methods, our instructors expose students to increased pressure as they progress in the Nami Ryu training curriculum. This pressure takes the form of working against skilled opponents and learning to handle a wide variety of potential situations.  

Ultimately, our goal is to avoid conflicts and bad situations while training for the functional ability to de-escalate them or quickly solve them with an appropriate response.
