Traditional JuJutsu/JuJitsu

JuJitsu is Japanese system of philosophy, combat and self-defense. It is one of the world’s oldest martial arts. JuJitsu is the parent of many martial art disciplines, including Judo, Aikido, NinJitsu and several systems of Karate (ie. Wado Ryu Karate). JuJitsu in its original form is unique among the martial arts in its effectiveness, simplicity, and full range of techniques. The art of JuJitsu excels in Self-Protection and Self-Defense. It depends on skill and technique rather than strength and speed. JuJitsu provides a lifetime recreational opportunity that can be practiced by any individual, regardless of size, age, or physical condition or handicap. Students learn Escapes Holds, Chokes, Throws, Weapons Techniques, Striking, Kicking, Kata, Rolling and Falling, as well as Healing Techniques and Restorative Massage.

DanZan Ryu JuJitsu

The Hawaii Zenyo JuJutsu Kai Martial Arts Academy teaches the JuJitsu system known as DanZan Ryu of the KoDenKan. This system was introduced to the Islands by Japanese born Hawaiian, Prof. Henry S. Okazaki, in 1924. Many older kama’aina in Hawaii will remember him well. DanZan Ryu is one of the most comprehensive and widely taught styles of JuJitsu in the United States. It teaches all of the deeper elements of what is known now as karate, aikido, judo, and ninjitsu. It is a complete system and includes participation in Judo Competition as well as JuJitsu A.A.U. Free Style and Kata Competition.
Students are free to compete in any style of martial arts, from Full Contact Karate, Boxing, Judo, Sambo, Aikido, Chinese Grappling, or in the new Arena (cage) Style “jujutsu” contests. Students can be further trained in basic wrestling skills for college & olympic level competition (greco-roman), or can go as far as the professional (“big time”) wrestling safety school.

Note: Contrary to popular belief, it is not necessary to “cross train” in martial arts when studying DanZan Ryu JuJitsu properly. With very few exceptions it has most of the elements of all other martial arts within it. Many other systems of martial arts are direct results of specific areas of JuJitsu. For instance there are several Karate sytems (ie Wado Ryu) that are direct studies of the atemi (striking and kicking)of JuJitsu. Judo is a sport based on JuJitsu. Aikido is an entire philosophical study of the esoterics and metaphysics of JuJitsu. And the list goes on to include several Massage and Healing systems.
The study of Ki, Kiai, Meditation, and Restorative Massage are essential to the system.
The advanced studies of Ki in our system can exceed most efforts of many other martial arts, even those directly related to JuJitsu.
Ki is an intricate and important element in all DanZan Ryu JuJitsu Yawara, Throwing, Grappling, and Striking arts.
There are over 150 basic techniques up to Black Belt and over 100 arts to learn after Black Belt.


The Japanese Art of Restorative Massage is one of the most highly regarded aspects of DanZan Ryu JuJitsu. It combines classic Japanese Massage, Hawai’ian Lomilomi, Acupuncture, Acupressure, Tsubo as well as the popular techniques of Swedish massage. Seifukujitsu is very important in learning the higher arts of JuJitsu.
Professor Okazaki, who perfected the restorative and healing arts associated with DanZan Ryu, was the Physical Therapist for Pres. Roosevelt when he stayed in Hawaii. The Okazaki family still maintains its massage facilities at the famous Nikko Massage in Honolulu, Hawai’i. Hachiro Okazaki (son of the founder S.H. Okazaki) and his son Keith Okazaki, have upheld the tradition of Okazaki Restorative and Healing Massage with such famous people as President Lyndon Johnson and many others.

The History of Our Schools, Teachers, and Organizations

The history of our Hui, traces its heritage to the original KoDenKan of Honolulu (Professor Okazaki’s dojo). In the late 1930’s and early 1940’s, while the American Jujitsu Institute (Prof. Sig Kufferath) continued to teach Prof. Okazaki’s system in Honolulu Hawaii, several of Prof. Okazaki’s students moved to the West Coast of the Mainland and established the American Judo and JuJitsu Federation, teaching the DanZan Ryu system at the KoDenKan in Chico, California (Prof. Bud Estes), as well at several schools in Oakland (Prof. Ray Law) and San Francisco (Prof. Willy Cahill - later an Olympic Judo Champions Instructor). The pre-war teachings were continued at the Bushidokan of Nevada, (Prof. Herb LaGue - Sensei, student of Professor Bud Estes) and where Sensei McLaughlin studied the system for 22 years and taught the system as a Senior Instructor for 15 years.
Arriving in Hawaii in 1992, Sensei McLaughlin taught at several locations on the Islands of Oahu and Kauai, and left these schools with firmly established basic arts to be continued on by their own sensei. After being nominated the AAU JuJitsu Chairman for Hawaii, Sensei McLaughlin established the Hawai’i JuJitsu KoDenKai Martial Arts Academy in Honolulu, Oahu, Hawaii, 1994. The HJK has moved on, and now the Hawaii Zenyo JuJutsu Kai is the new martial arts college carrying on in it’s place. The HZJK is located at the Daijingu Shinto Temple of Hawaii, 61 Puiwa, Rd, Nu’uanu Valley, Honolulu, Oahu, Hawaii, USA.

The HZJK is proud member of the Bushidokan Federation, and the A.A.U.

Instruction & Curriculum

The HZJK believes that excellence in Martial Arts can be gained through the mutual cooperation and growth of the student and the instructor. They each learn from the other. The founders, as well as the current masters of instruction, share the belief that it is necessary for the mind, body, and spirit to be in harmony for personal growth and development. Ki is a daily study and is included in every technique and concept taught. It is refined in all the lists and is used extensively in the studies of anatomy. The HZJK  also believes that Martial Artists should be knowledgeable in Literary, Social, Philosophical, and Fine arts as well as the Physical arts. Our students have an extensive academic reading list.
