William Perkins Sensei…
Location: Olathe Kansas


I began training in Ki Aikido with Dr. Andrew Tsubaki Sensei in 1995 and continued to be Tsubaki Sensei’s direct student until his passing in 2009. I earned a Sandan(3rd degree black belt) in Shin Shin Toitsu Aikido, and a Shoden in Ki Development, while under the direction of Tsubaki Sensei.

I am now under the direction Koichi Kashiwaya Sensei, Chief Instructor for Ki Society USA. He currently acts in an advisory role between Ki Society International Headquarters in Japan and other USA Chief Instructors.
