Yoshiki started training martial arts in Sumo wrestling at age of 9 and later practiced Judo and Jiu Jitsu in Japan. He competed in many tournaments in Sumo wrestling and Judo.
In his late teen years, Yoshiki, who was already sailing the world as a merchant marine, began immersing himself into intense strength training, long-distance running, and playing Rugby.
Yoshiki discovered Systema in 2010 and started in-depth training with Kwan Lee in 2011. He quickly became a full instructor for Vladimir Vasiliev after completing extensive immersion training with the Master at Systema Headquarters, Toronto, and then began teaching classes at HQ as well as internationally.
