Traditional Japanese Martial Arts

"No Challenge; No Resistance; No Injury."

About Our Style:  Hakkoryu Jujutsu 
Hakkoryu Jujutsu was founded in 1941 by Shodai Soke Okuyama Ryuho. Okuyama Soke was a master instructor of
Daito-ryu Aiki-Jujutsu and Asian medicinal practices, or specifically, Shiatsu (finger pressure healing methods). Like his colleague and fellow Daito-ryu student, Morihei Ueshiba of Aikido, he wished to create a system of humane self-defense that could be quickly and easily learned by anyone. The art has a strict moral code and is soft in application, so it may be practiced by anyone.

Hakkoryu techniques are closely related to Daito-ryu Aikijujutsu and by extension, modern Aikido, but it is the influence of Asian medicine, and a strict moral code that distinguishes the style.  Another distinguishing characteristic of Hakkoryu Jujutsu is the school’s emphasis on pressure points (tsubo) and manipulation of the opponent's body through both the skeletal structure and the body's meridians (keiraku).

The techniques of Hakkoryu are passed down in the form of kata or waza sets known as “Gi”. Each formal waza set (Shodan-Gi, Nidan-Gi, Sandan-Gi, etc.) has a number of fundamental (omote) techniques that must be learned before the student can progress to the next level. Each level also contains Gensoku, which introduce the core principles of Hakkoryu to the student. The theory behind focusing on the core principles is that these can be mastered much more quickly and efficiently than memorizing hundreds or even thousands of techniques to cover every conceivable scenario. Once learned, the core principles can then be easily applied to a multitude of self-defense situations. Class time is typically divided equally between the formal waza sets and these applied self-defense techniques.

The three major characteristics of Hakkoryu are: no challenge, no resistance, no injury. With Hakkoryu, for the first time, the eyes of the dragon are drawn.” – Shodai Soke Okuyama Ryuho, Founder of Hakkoryu Jujutsu

Hakkoryu Koho Shiatsu (One-Finger Healing Method):
Shiatsu is a form of traditional Japanese therapeutic bodywork based on the theoretical framework of eastern medicine. Koho Shiatsu is the unique method of this therapy founded by Shodai Soke Okuyama Ryuho in conjunction with Hakkoryu Jujutsu. While Hakkoryu Jujutsu applies pressure techniques on Keiraku (the body’s energy lines, according to traditional eastern medicine) to defend oneself, or pin down an opponent when one is being attacked, applying pressure techniques on Keiraku is also the essential method utilized by Koho Shiatsu. In its basic practice, pressure is applied with the thumb or fingers against various meridians and pressure points (called Tsubo) on the patient’s body.  It can be said to be a method of “helping one’s body to heal itself”.  In Hakkoryu, one is learning a martial art while at the same time practicing Shiatsu techniques created by the founder. Koho Shiatsu, as a solid therapeutic method, is perfectly complementary to the techniques of Hakkoryu, as a martial art.

Within our Dojo, classes in Hakko-ryu Jujutsu are conducted through public (Thursday evenings), private, or semi-private lessons. This ensures that student's get significant attention through direct training with the instructor. Progression is based on the motivation of the student, and often faster than in other class formats.

Our study of Hakkoryu is as an official registered Hakkoryu Dojo (
Hakkoryu Shinwakan Dojo #48102), under the direction of Devon Smith Sensei, who holds the rank of Menkyo Kaiden Sandaikichu Shihan under Nidai Soke Okuyama Ryuho, and operates the Kenshinkan Dojo in Clinton Township, Michigan.  All ranks awarded at our school are issued directly from Nidai Soke Okuyama and the Hakkoryu Sohonbu (headquarters) in Saitama, Japan.

Hakkoryu Jujutsu:  Japanese Self-Protection & Healing Arts

What is Hakkoryu Jujutsu?


Hakkoryu Jujutsu is a soft and subtle form of Aiki-Jujutsu that focuses on complete relaxation and a non-aggressive approach to self-defense. Jujutsu translates as the "art of yielding", and indicates that the exponent does not resist the power of the attacker directly, rather, they yield to it, harness it, and use it to defeat the opponent. Therefore, Hakkoryu Jujutsu can be applied with minimal strength and can be used by anyone, male or female, young or old, to successfully defend themselves against an aggressor without causing serious injury.  The three main tenants of Hakkoryu Jujutsu are:
