Morio Higaonna (Higaonna Morio, born December 25, 1938) is a prominent Okinawan karate practitioner who is the founder and Chief Instructor of the International Okinawan Goju-ryu Karate-do Federation (IOGKF).  He is a holder of the highest rank in Goju-ryu karate, 10th dan.  Higaonna has written several books on Goju-ryu karate, including Traditional Karate-do: Okinawa Goju Ryu (1985) and The history of Karate: Okinawan Goju Ryu (2001). Martial arts scholar Donn Draeger (1922–1982) reportedly once described him as “the most dangerous man in Japan in a real fight.”

The following videos show Morio’s own supplementary strength & conditioning training, something which many Karate-ka avoid entirely.
