"Learning techniques but not being able to apply them is

like learning your ABC's but not being able to read."


The history of JunsaKwon starts with the Korean martial art of Hapkido. Hapkido is a Korean style known as "The Way of Coordinated Power and Spirit". It was founded by Choi Yong Sool (AKA: Asao Yoshida/1904-1986). Choi had learned Daitō-ryū Aiki-jūjutsu from its headmaster Sokaku Takeda while living in Japan from 1915 to 1945. Shortly after World War II Choi returned to Korea and began teaching Jūjutsu, referred to also as YuSul by Koreans and later Hapkido. 


“Hap” is harmony or balance, “Ki” denotes the essence of power/energy/spirit and “Do” means the way/path/method. The grappling and joint locking techniques of Japanese Daitō-ryū Aiki-jūjutsu were combined with Korean kicking. According to my teacher, Yu Chong Su (Song Tan City, So. Korea), many of the modern kicks used in today's Hapkido were derived from Tae Kyun (Ancient Korean Kicking Art) and were not part of the original Jūjutsu that Choi brought from Japan, this was added and taught by other instructors. The Chong Su Kwan Hapkido shown to myself and other students of that era  was unfiltered and more resembled the Aiki-jūjutsu that was taught to him by Choi.


Going Rogue and teaching the style of the Warriors Fist.

I have spent a life time studying the martial ways as it pertains to self-defense. Training in such skills at Eskrima, Gung Fu, Aikido, Western Boxing, American Kempo,  Jiu-Jitsu as well as my own chosen style of Hapkido.

When I began my formal martial arts training in 1978, it was under the tutelage of the Fowler Brothers in Aurora, Illinois. The training received at that dojang was unlike what you see in Hapkido schools today. Today, what you see are showy and flashy techniques that are ultimately useless in defense and give the practitioner a false sense of security. The Fowler's wanted the students to have true skills and pushed the students hard. It was a different time and the martial arts schools were found everywhere. Unlike most of the training centers around my area, the Fowlers were the only ones that were not interested in teaching sports, their goal was 100% self-defense and I loved it. At that time in my life I weighed 110lbs. with a height of 5' 6", I was small, I needed to defend myself. The idea of training for sport seemed foreign to me, why train in the martial arts if not to defend yourself? That idea was ingrained in me at that time and would remain with me the rest of my life. I have since learned that there are many reasons why people train, but at that time in my life there was only one, self-defense.

My martial arts journey would later, via my military service, take me to South Korea where I was privileged to train with Grand Master Yu Chong Su, a man who embraced the martial arts as a life style. Although he appreciated the Hapkido skills that I had acquired in the states,  it was different from what he was teaching, there were times that I felt it was an entirely different system. He explained to me that the Hapkido  being spread all over the world were different interpretations of it's instructors and would continue to change as it passed from teacher to student. It had already became very different from what Choi Young Sool had brought to Korea from Japan. Master Yu would explain that the Hapkido he, and many of his colleagues, were teaching was closer to the original jūjutsu as they were directly influenced and taught by Master Choi. During my time training in Korea, I learned to appreciate the skills and the hard lessons that I received. The country and it's people would forever influence my continued martial arts journey.

As I have continued to train in other martial arts, I've learned to appreciate what they all have to offer and to take what I felt specifically applied to me and discard the rest. 

After years of modifications and constant updates I realized that what I teaching was very different from the original curriculum. As the curriculum continued to evolve, I made the decision to rebrand the system into something different, something that would retain its roots but not be bound by the restrictions of traditional styles. Merging weapons and ground grappling the art of Junsakwon was unveiled.

Why Junsakwon?

Junsakwon is an extremely realistic and versatile discipline of self-protection. Joint locks are a strong part of the training as well as throwing techniques that are similar to those in Judo but with an emphasis on constant contact. It is based on scientific principles of anatomy, combat tactics and strategy, focusing on a method of fighting centered around controlling the opponent.

Junsakwon is a combat grappling system that employs joint locks and striking in fast counter-attack movements designed to quickly disengage you from your opponent. 

In JSK every method of attack is studied, along with corresponding defensive responses. The student learns how to analyze a threatening situation quickly and, if necessary, to utilize the appropriate self-defense response. Strikes and kicks are more target specific in that they are aimed at vital spots on the human body to include the lower legs and joints. 

Principles of JSK 

JSK was designed to help the defender control the distance of the opponent and control the opponent should the distance be compromised. 


  1. Striking: Utilizing your feet and hands as striking tools by perfecting your attacks and properly targeting the weak & vulnerable spots of the human body. 

  2. Joint, Arm & Body Locks: Restraining the opponent's movements by seizing control of the body and utilizing various types of joint locks.

  3. Throws: The takedowns and throws used in JSK are similar to the ones found in Aiki-Jūjutsu and Judo but with a strong emphasis on self-defense and the surroundings & terrain. 

  4. Weapons Training: Learn to utilize standard weapons (both blunt & bladed) and to turn mundane objects into effective impact & control tools. 

  5. Grappling: Grabbing, holding and controlling your opponent is the core of the JSK system and required whether you're standing or on the ground.
