An association of traditions and visions developed over 3,500 years

       From our simple beginnings to our present-day teachings, the basic principles of the late Judo Master, Professor H. Seishiro Okazaki, have been enthusiastically embraced by each and every one of our deeply committed students in their daily lives.  Professor Okazaki's Kodenkan Danzan Ryu Judo & Jujitsu system is taught world wide.  Professor Okazaki balanced his system with healing (kappo) and defensive (Sappo) arts drawn from Chinese and Japanese traditions. 

       The Congressional Record reports Professor Okazaki with having treated medical conditions of President Roosevelt, actress Shirley Temple, comedian George Burns, Johnny Weissmuller(Tarzan) and other notables of his time.  The Okazaki healing arts were so effective that President Roosevelt asked Professor Okazaki to become his personal therapist and relocate to Washington DC. 

        Professor Okazaki was also known as a pioneer for breaking with the norms of the day and teaching non-asian men and woman self defense and healings arts.  His system of healing and defensive arts is recognized internationally.  His 1922 defeat of professional English boxer, Carl "Kayo" Morris, brought world wide recognition of the Danzan Ryu school.

        The late Professor Lono Ancho and Sig Kufferath, both students of Professor Okazaki, carried this tradition forward.  As a student of the late Professor Lono Ancho and Kufferath, I've accepted the responsibility of preserving, practicing and teaching this ancient art form.  I have introduced thousands of students in the last fifty years to the Okazaki teachings.  I would be honored to introduce you to this great art form.





Become an Okazaki Student

       I became a student of the Danzan Ryu school in 1969 at East Stroudsburg University.  As a student Senator, I assisted Dr. William Gessner, Club Director, in developing the school judo club and its financial support.  In 1973, I was invited to become a student of the late Professor Ramon (Lono) Ancho Jr. Professor Ancho at the time was the West Point Academy Judo coach and Assistant Commandant of the New York Military Academy.   I remained his principal student and friend until his passing in 2003.  During those 30 years, Professor Ancho and I developed a long standing personal and student-teacher relationship with the late Professor Sig Kufferath and Professor Tony Janovich.  We co-founded the Kodenkan Danzan Ryu Jujitsu Association(KDRJA). 

       I have authored numerous texts on the art which are available on  I am also recorded in the Martial Art Hall of Fame for my work in preserving this art form.  Received Okugi certifcation 2003.  I was advanced by the national organization to the rank of Shichidan (7th degree black belt) in 1998 and awarded the title of Professor.

       To a large extent, our association is given purpose through the commitment and enthusiasm of its members to teach the arts and sciences of Judo and Jujitsu.  Our students are taught both self defense techniques and healing arts from a list of several hundred arts.  Students progress at their own pace with a separation between adult and junior students.  Belt ranking is accordance with National Standards.  We limit each class size to 8 students.        This program ensures a teacher-student ratio of 1 to 8.  Classes are Monday evenings and Saturday mornings. $65.00 per month.  The first month is always free.  It gives you a chance to experience the Okazaki arts. Senior classes (Black & Brown Belts) and private lessons are by arrangement.  E-mail us for details at
