Gozo Shioda
In 1955, along with Gozo Shioda Sensei, he co-founded Yoshinkan Aikido. In 1957, the Yoshinkan was visited by US Senator Robert F. Kennedy and Prime Minister Nakasone. Terada served as chief instructor of the Yoshinkan honbu until 1961 when he left Tokyo to teach aikido at the US Naval Base in Yokosuka. It was here that his most senior student, Amos Lee Parker began his aikido life.
