- The Okinawa-den part of the Koyama-ryu system is made up of the Kojo-ryu, Hakutsuru-ken (White Crane Fist) and Okinawa Kobudo kata, around which all the practitioner's training revolves which is enriched by the training of other kata, exercises and methods also deriving from other styles and systems such as Shurite, Nahate and above all the Kingai-ryu of the Matayoshi family.
- The Nihon-den part of the Koyama-ryu system contemplates the study of Japanese taijutsu/jujutsu techniques, tojutsu and some weapons of the Japanese bujutsu tradition, such as jo, shuriken, etc. Examples of schools of particular interest are the Mondo-ryu, Negishi-ryu, Toyama-ryu, Yamamoto-ryu, etc. and there is also a study dedicated to shinobi strategies interconnected with some of these schools.
