The Yudansha-Kai is comprised of certified blackbelt  members of the Columbus Dojo and the IOGKA. Each Yudansha-Kai member is a Goshukan-Ryu Karate student  of Garry Parker, whether they are members of the IOGKA member dojos, or personal students of Parker at the Okinawa Goshukan-Ryu USA Honbu Dojo.  The Yudansha-Kai members receive additional training in the form of quarterly workshops, seminars, and clinics held at the USA Honbu Dojo, and seminars/workshops hosted by authorized IOGKA member Dojo.
