Hakuda Kempo Toshu Jutsu was formalised by SimonKeegan (5th Dan Renshi) and this document traces his principal teachers in traditional Karate but also influential sources derived from other arts. Lineage is perhaps the wrong word because things in martial arts are very seldom linear.
The primary influence on my Toshu Jutsu is Shotokan/Budokan Karate. Initially I was taught by my father David Keegan (and not to mention the boxing and Jujutsu tradition on my mother’s side of the family.)
My formal Karate teacher from the 1990s Shihan Stephen Bullough (Bushidokan) who had in turn studied both Shotokan and Budokan (under M Newton a student of Chew Choo Soot) among others.
From the 2000s my teacher was R Carruthers and later I trained and graded with his teacher P Handyside who trained under masters like Kanazawa Hirokazu in Shotokan and Chew Choo Soot in Budokan. The Budokan style is significant because Grandmaster Chew combined Kanken Toyama’s Karate (including Shuri Te, Naha Te and Tomari Te) with elements of Shotokan, Kung Fu and indigenous Malaysian arts.
I was graded 5th Dan in the same Dojo where Chew taught Shihan Handyside. Kanazawa Sensei also studied Yang style Tai Chi and Okinawan Shorin Ryu and Goju Ryu. Kanazawa trained with Funakoshi who trained with Azato who trained with Matsumura who trained with Sakugawa.
Thus, I regard Shotokan/Budokan as my primary influence. Secondary is Goju Ryu, Jujutsu, Quan Fa and several other arts.
