[1] Gosoku-ryū, "the style of force with speed", incorporates the methods of Goju-ryū and Shotokan karate with aikido, jujitsu, and judo.

Advancement through the ranks, as marked by belt color, is a process signifying progressively greater control and coordination of mind and body.

Gosoku-ryū teaches quick leg sweeps and take-downs; in kumite, attacks often end on the floor.

Fast footwork which adds speed and power by utilizing the rotation of the hip makes Gosoku-ryū different from other styles.

Many weapons are practiced in the dojo: Kubotan, Tonfa, Kama, Jō, Bokuto, Bokken, Shinai, Tsue (walking cane), and the Katana (Japanese sword).

[3] Kubota trained with Taira Shinken learning ancient Kobudo katas while developing his own for his school.
