Senior Instructors

We are extremely lucky to have a wealth of senior Aikido instructors resident in Western Australia, many of whom also train and attend events as students themselves. 

Hugh Derham Shihan (7th dan)

Leederville Dojo

Hugh Derham Sensei started training Aikido in the early 1970’s and his training path took him to Hombu dojo, the World Aikido Headquarters of Japan. It was not long before Hugh Sensei learnt about Sugano Shihan who was an original student of the Founder, who had been sent to Australia to establish Aikido. Hugh Sensei moved to Sydney to train and study Aikido under Sugano Shihan. He received his Shodan in 1978. Under the direction of Sugano Shihan, Hugh Sensei established the first Aiki Kai dojo in Western Australia in 1980, and has been teaching in WA ever since. 

Hugh Sensei is the most senior Aikido instructor in the state and served as the Area Representative for Western Australia for over 20 years. He is currently ranked 6th dan.  Hugh Sensei is the chief instructor of Leederville dojo and teaches Australia wide. 

When Hugh is not teaching Aikido he is saving the world as a General Practitioner (GP) and encouraging natural medical treatment and healthy living through Nutritional medicine
