Onishi Eizo (Kancho Sensei)


The Meaning of Koei-Kan Karate-Do


The name Koei-Kan was suggested to the founder of the system, Onishi Eizo, by his mentor, the late Master Toyama Kanken. 

The fundamental translation of Koei-Kan from the Japanese is: happiness (ko), prosperity (ei), and hall or house (kan). 

This definition is truly expressive of the nature and purpose of Koei-Kan.

To cultivate ourselves fully in an attempt to make the greatest use of our lives is the aim of Koei-Kan study. The development of this type of existence is beneficial to all life, as well as to that of the individual. The sentence "Prosper with happiness toward the future" has often been used to describe the meaning of Koei-Kan, and it is mentioned here because it perhaps best exemplifies the intrinsic values of the Koei-Kan system.
