While his father supervised his early budo training, Suenaka Sensei is fortunate to have had the opportunity to train with many of contemporary budo's most celebrated practitioners, beginning in Honolulu, Hawaii and later, in Japan and Okinawa. Suenaka Sensei brings his rich experience with these great teachers to his instruction at Suenaka School of Martial ArtsTM.
