"The founders of BUDOKAN studied a number of Martial Arts including Chinese Kung-fu, Tae Kwon Do, and several styles of Karate-do including Shito-ryu, Shotokan and Keishinkan. Keishinkan is a minor style of the Shuri-Te strain and is not widely known even in its country of birth. It comes from the line of Toyoma Sensei and the excellent qualities of their instructors are well known in Australia, Malaysia and elsewhere.”
