It has been said that origin of Japanese wrestling dates back 1,960 years when two men stood up face to face and kicked each other, one kicked the other in ribs, stamped on and crushed his waist, killing. This has been regarded as the origin of jujitsu.

About 400 years ago the Takenouchi School of Jujitsu was systematized. Sixty years later a Chinese came to Japan and thought the art of boxing. Forty years later, another Chinese visited Japan and introduced an art of seizing one`s opponent. Through the process of elimination and harmonization, a new art known as “YAWARA” was created and popularized. This is the origin of present day jujitsu.

Jujitsu is a Martial Art used in Feudal Japan. It was the empty handed combat art of Samurai, the professional soldiers of the era. It was used as a last resort on the battlefield when a Samurai`s spear was lost, sword was broken, throwing irons were gone, knife had fallen out of the belt, and wife had forgotten to pack his weighted chain.

Jujitsu is the art that concentrates specifically on throws and join manipulations in response to attack although striking and kicking are practiced to produce a comprehensive system of self-defense. The majority of class time is spent throwing and locking.

One of the fundamental principles of Jujitsu is that an attack should not be countered by brutal force, but redirected instead. A jujitsu practitioner hopes to use the energy from an attack to trip the attacker up in some way.

This yielding concept also makes Jujitsu a Martial Art that is difficult to master.
Timing and balance must be perfected, so that practitioner can always be ready to respond to the opportunities presented to him by the attacker. This takes many years to master. Frankly, it`s much easier to learn how to beat the snot out of someone. Jujitsu allow greater flexibility of response to an attack,however it can be very passive, neutralize an attackwithout hurting the attacker, and can also be extremely destructive, utilizing all of the practitioner’s weight and balance against a small part of the attacker, such a joint or weakness in his stance.This allows jujitsoka to respond to the given situation with an appropriate amount of force.

Many combat – derived martial arts are actively practiced, but no longer really in use because they do not allow a range of responses appropriate to living in a civilian society. Jujitsu is one of the few than can still claim to be used in a professional capacity, such as by police, prison, emergency medical staff etc.

The older term JUJITSU or “gentle art”, gave way in later years to word JUDO or “gentle way”, which stressed the ethical and philosophical concept of “do” or “way” of harmony with natural law.  When the Japanese Ministry of Education adopted a limited from of the national art (KODENKAN JUDO) for sport instruction in the secondary schools, JUDO came, in time, to denote only the sport based JUJITSU, and JUJITSU remained the only word to denote the entire art.
The used of both words in the name of the AMERICAN JUDO AND JUJITSU FEDERATION stressed the importance of both aspect of the art; JUJITSU techniques of defense and restoration embody the ancient philosophical and moral training aimed at perfection of character in addition to the sports-directed system of physical culture and mental cultivation now know as JUDO.

Danzan Ryu is the system of jujitsu created in the early 1920s by Henry Seishiro Okazaki . DANZAN RYU meaning (Sandalwood MOUNTAIN SYSTEM). He named this to honor the memory of his Kung-Fu teacher Wo Chang.  “DANZAN” is also the word the Chinese use to describe the Hawaiian Islands.

The founder of Danzan Ryu Jujitsu , Henry Seishiro Okazaki was born in Fukushima prefecture on the island of Honshu, Japan January 28, 1890.When he was 16 years old, he moved to Hilo, Hawaii Island. Three years later he was examined by the doctor who diagnosed him with incurable tuberculosis. With courage and desperation, he decided to learn jujitsu and join school of Yoshimatsu Tanaka. After thousands of hours hard training Okazaki`s tuberculosis healed and he developed a strong “iron-like body”. He believed that he owned his life to jujitsu and devoted the rest of it to the teaching and promoting of the art.

Studying under various masters in Hilo, Hawaii, he mastered the YOSHIN, IWAGA, and KOSOGABE schools of JUJITSU by practicing diligently six night a week. In addition he studied OKINAWAN KARATE, CHINESE KUNG-FU, HAWAIIAN LUA, and FILIPINO KNIFE PLAY as well as AMERICAN BOXING, and WRESLING. In 1924 he tour Japan, visited more than 50 dojos (schools) and acquired 675 different kinds of techniques or forms. He also made a special study of KAPPO and SEIFUKUJITSU (Restorative Massage) because he recognized that the virtue of JUJITSU lay in possibility of reversing the effects of deadly or disabling arts by restoration and treating. Gradually Professor Okazaki evolved a system of JUJITSU comprising courses for men, women, and children which included methods of defense against the knife, sword, club, gun, and bayonet, in this system.

Professor Okazaki named his school KODENKAN (School of Ancient Tradition) Danzan Ryu. He stressed the ancient system of philosophical and moral training while retraining the best of arts of self-defense and of restoration together with system of physical culture and mental cultivation known as sport JUDO. Kodenkan may be rendered “THE SCHOOL IN WHICH THE SENIOR TRANSMITS THE TRADITION” This translation describes the KODENKAN method for instruction: Senior students teach junior students in spirit which Professor Okazaki declared was inherent in Hawaiian word KOKUA: “To help one another”, or OHANA “Family”.

In 1930, Professor Okazaki opened the NIKO SANATORIUM OF RESTORATIVE MASSAGE in Honolulu, where he subsequently earned international reputation for his skill as a therapist.  The same year he opened his Kodenkan Jujitsu School, now is known as the AMERICAN JUJITSU INSTITUTE OF HAWAII.

His live from that time forward was devoted to instructing worthy Americans, without regard to national origin, the art and sciences of JUDO and JUJITSU and to developing who would introduce his system throughout the United States. It is safe to say that when Professor Okazaki died in July 1951, the thousands of students had studied in his school. His system the DANZAN RYU JUJITSU, remains today the most widely thought system in the United States.

On the mainland, several disciples whom Professor Okazaki had initiated, the A.J.J.F Professors John Cahill, Bud Estes, Ray Law, Dick Rickers into the highest arts of the KODENKAN system banded together in 1949 to attempt to make a reality of Professor Okazaki`s dream to have a school teaching his system in every state of union.

Professor Ray L.Law (now deceased) had established the Oakland judo school in 1939 and had been followed shortly by Professor John Cahill (deceased).On May 21, 1958 , the confirming council organized the A.J.J.F as a non-profit organization under the law of the state of California. Since that time the A.J.J.F has grown steadily until it is now represented by school from California to New York, from Canada to Florida, and through affiliations with the International World Judo Federation maintained friendly relations with schools throughout the world which adhere to the same high standards of ethics and sportsmanship.
