We perpetuate the teachings of Professor Seishiro H. Okazaki, founder of Danzan Ryu Jujitsu.

Kodenkan
Kodenkan is the official name of the school or Dojo established in Honolulu, Hawaii, circa 1932, by our founder Professor Henry Seishiro Okazaki.
The first syllable Ko means “ancient” or “senior”. The second syllable den means “tradition” or “transmission”. The third syllable kan means “school”.
Therefore, the name Kodenkan may be translated in two ways. Each way accurately characterizes the jujitsu system (Danzanryu) and the method of instruction taught by Professor Okazaki at the Kodenkan.
First, Kodenkan may be translated as “The School of the Ancient Tradition”, and in fact, the arts of Danzanryu taught at the Kodenkan are based on the arts of ancient jujitsu schools.
Secondly, Kodenkan may be rendered as “the school in which the seniors transmit the tradition”. This translation describes the Kodenkan method of instruction in which the senior students teach the junior students in the spirit which Professor Okazaki declared was inherent in the Hawaiian word “kokua” or “to help one another”.
The Kodenkan Yudanshakai was established in January 1967, for the primary purpose of continuing to carry on this ancient tradition of the Kodenkan and Professor Okazaki.
