Goju-ryu (the hard/soft style) is an art which combines traditional Okinawan techniques with both internal and external Chinese principles. The soft (ju), internal Chinese style concentrates upon circular movements and the development of chi (vital energy), while external, hard (go) principle rely upon physical strength. The combination of these principles make Goju-ryu a close-range, fighting system that concentrates on efficiency of movements as well as a personal development.

A signature quality in this system is the emphasis that is placed upon combining soft circular blocking techniques with quick strong counter techniques delivered in rapid succession. The movements contained with Goju-Ryu kata are intended for self-defense and not for sport. Short, circular blocks, powerful holds and locks, efficient punching maneuvers, and kicking techniques targeted to the lower body characterize the art that Miyagi carefully developed.

Its popularity was primarily due to the teaching success of Kanryo Higaonna (1853-1915) who opened a dojo (school) in Naha using eight forms brought/introduced from China.
