The advent of Gichin Funakoshi's introduction of Okinawan Karate to Japan in the early 1920's, the popularity of karate began to grow. Soon, other Okinawan masters began to travel to Japan to proliferate their arts. One such man was Kanken Toyama, whose Okinawan name was Kanken Oyadamari. A school teacher by profession, Toyama 's chosen avocation was the instruction of karate. He started his karate training at the age of 9 with a master named Itarashiki. His major teacher was the famous Itosu Yasutsune, with whom Toyama studied for 18 years. In 1907 Toyama became Itosu's assistant at Shuri dojo.
