The first character Ko means ancient, of olden times or senior. The second character den denotes transmission or tradition. The third character kan means school.
The name Kodenkan, therefore, may be translated in two ways. Each way accurately renders the characters, and each way accurately characterizes the Okazaki Judo and Jujitsu system.
First, Kodenkan may be translated as The School of the Ancient Tradition, and in fact, Kodenkan system is a synthesis of the best arts of the ancient jujitsu schools.
Second, Kodenkan may be rendered as The School in which Seniors Transmit the Tradition. This translation describes the Kodenkan method of instruction: senior students teach junior students in the spirit which Professor Okazaki declared was inherent in the Hawaiian word kokua, to help one another.
