Shugoro Nakazato was born on 14 August 1920 - Aug 24, 2016, in Naha City, Okinawa.

He began training in karate when he was sixteen years old.  He studied for six years with Seiichi Iju until World War II.  The only interruption of Nakazato's martial arts training occurred when the war broke out during which time Nakazato served in the Japenese army.

Following the war, Nakazato began his training with Choshin Chibana.  In 1951 Nakazato received his instructor's certificate, which was followed two years later by the opening of his Aja Dojo.

In 1955 Nakazato formed the Okinawa Karate-do Renmei Federation which was comprised of Goju-Ryu, Uechi Ryu, Matsubayashi Shorin Ryu, and Kobayashi Shorin Ryu.

In 1960 the Okinawa Karate Federation promoted Nakazato to 8th Degree Black belt.  Seven years later, Coshin Chibana promoted him to 9th Degree Black belt and bestowed the title of Hanshi.  When Master Chibana died in February 1969, Shugoro Nakazato inherited the leadership of Okinawan Shorin Ryu Karate-Do.  In 1980, he was promoted to the rank of 10th Degree Black Belt, Grand Master of Shorin Ryu Shorin Kan Karate.

Shugoro Nakazato's kobudo training began in 1936 under Seiro Tonaki.  Tonaki trained Nakazato in sai, bo, nunchaku, tonfa, and kama.  In 1955 Nakazato furthered his bo skills by training under Masami Chinen.

Shugoro Nakazato passed on the association to his son Hanshi Minuro Nakazato.
