“The Keeper of Okinawa’s Soul of Martial Arts”
Kanken Toyama, martial arts
grandmaster was born in Shuri, Okinawa, to a noble family, and given the name
of Oyadameri Kanken. His profession was
a Japanese teacher, and his chosen field was the instruction of
karate-do. He was one of only two
students to be granted the title of Shihanshi (protégé). Funakoshi Gichen was the other to receive
this title from Itosu Anko. Later Toyama
was given the title of master
instructor, and developed the foundation
for the Shūdōkan karate style.
He trained under Itosu Anko, and Itarashiki primarily, also under Ankichi Aragaki (a master of Monk Fist and White Crane Kung Fu), Azato Anko, Choshin Chibana, Oshiro, Tana, Yabu Kentsu and Kanryo Higashionna. Master Toyama was one of only three men to have the privilege of studying directly under Master Itosu and Master Higashionna, two of Karate’s most important figureheads of that era.
At age nine, he began karate (Shuri-te) training under Ankō Itosu, remaining a student until Itosu died in 1915. He studied Naha-te under Kanryō Higaonna and Tomari-te under Ankichi Aragaki.
Given this diverse martial arts
background, the Japanese government recognized Toyama's prowess, and awarded
him the right to promote to any rank in any style of 
Okinawan karate, with the
title of master instructor.
In early 1930 he returned to Japan and on March 20, 1930, he opened his first dojo in Tokyo. He named his dojo Shu Do Kan meaning "the hall for the study of the karate way". Toyama taught what he had learnt from Itosu and the Ch'uan Fa and did not claim to have originated a new style of karate.
In 1946, Toyama, now a Dai
Shihan, founded the All Japan Karate-Do
Federation (AJKF) with the intention of unifying the various forms of karate of
Japan and Okinawa under one governing organization for the exchange of ideas
and technique. The 
Federation became an
authority for rank homologation and advancement issuing rank certification, and
also created a forum for competition.
The competition group later pioneered full contact sparring using
modified kendo protective equipment. Dr.
Tsuyoshi Chitose, founder of Chito Ryu Karate Do served in several senior
positions in the Federation including President.
Toyama authored two books: Karate-do Taihokan and Karate–do. Toyama’s specialities in Karate-do were the strong gripping methods of Itosu and Itarashiki, and similar Chinese methods of finger and hand strengthening. Toyama sensei was also known to have studied and taught Tai Chi. After the war Toyama became good friends with Yoshida Kotaro and spent time teaching a young Richard Kim in the Yokohama section where Kim owned a bar with his wife.
In 1949 Toyama was awarded the special title of honor, Meijin, by the Governor of Okinawa.
Shudokan karate-do is a composite system which also includes Kobutjutsu (Ancient Arts) referring to the Special weapons practice of Okinawa, and many styles of Okinawan Karate-do.
There are also katas unique to Shudokan karate-do emphasizing circular motions and multiple power sources.
