The American Judo and Jijitsu Federation (AJJF) traces its history from Master Okazaki. Several of his students came to the mainland in the late 1930's established schools and began teaching the techniques of Danzan Ryu. Four of Master Okazaki's students, founders John Cahill, Bud Estes, Ray Law, and Richard Rickerts wished to help fulfill Master Okazaki's dream of having a Danzan Ryu Jujitsu school, in every state of the union. They founded the AJJF, which was incorporated as a non-profit State of California corporation on May 21, 1958.

Since that time the A.J.J.F has grown steadily until it is now represented by schools (dojo) 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. The AJJF is reported to be the largest martial arts organization in the United States.

The AJJF  looks after the interests of over two-thousand members. Most individual members of the AJJF are associated with AJJF schools, although this is not a requirement. Membership in the AJJF is non-discriminatory. As a member of the American Judo and Jujitsu Federation, you become part of a national organization that provides many benefits. Among them is a subscription to the Kiai Echo, the official magazine of the AJJF.

The AJJF sponsors many events around the United States in which you may participate as a AJJF member through your membership and training at Honshin Kan. For example some major events include the National Convention in early spring each year, Camp North (northern California) and Camp South (Mt. Palomar, San Diego, CA), Northeast Regional Spring Clinic, (Pennsylvania), Fort Jones Kids Camp during summer vacation, Brown Belt Weekend, and Black Belt Convention. There are many weekend clinics with visiting AJJF and Associate Professors throughout the year in dojos spread from Hawaii to New York.

The AJJF promotes the Danzan Ryu system of Jujitsu, an effective system of self-defense that incorporates physical and mental training within a philosophy of ethical and moral development.  The AJJF especially promotes the fundamental principle of Danzan Ryu Jujitsu expressed by Professor Okazaki in the Hawaiian Kokua-helping and being of service to others. As a result you will form many close relationships that last for decades as you train at Honshin Kan and in the AJJF expanding community.
