Roy Y. Suenaka

Wadokai Aikido is an aikido organization founded by Suenaka in 1975 and it is based in Charleston, South Carolina. Wadokai teaches Suenaka-ha Tetsugaku-ho Aikido, which means "Suenaka style, philosophical way." Wadokai Aikido has dojo throughout the United States and China. Suenaka was a 1st generation student of aikido founder Morihei Ueshiba. Originally organised as "Aikidos" American International Ki Development and Philosophical Society, Wadokai Aikido teaches a method of aikido that is both martial and spiritual. This philosophy is where the term "Complete Aikido" comes from.

In 1961 he was transferred again to Naha, Okinawa. At the airbase there, he set up his own dojo, and aikido became popular with the servicemen stationed there.

In 1958, Suenaka enlisted in the United States Air Force. In 1960, although he originally planned on becoming a pilot, he put this on hold to go to Japan to study under O'Sensei. He worked primarily as an electrician and engineer. At his request, he was transferred in 1961 to Tachikawa Air Base in Japan, which enabled him to study directly under Morihei Ueshiba at the Hombu dojo in Tokyo.

As well as training with his father, Suenaka also studied under Henry Okazaki and James Mitose. He also studied judo. Suenaka attended Koichi Tohei's aikido demonstrations in 1953, and at his father's behest began training primarily in that art. He also took up the study of kendo in 1955.
