Our Spreading Project is called Okinawa-den Koyama-ryu Kobujutsu Taigishinkan™ (or simply Kobujutsu Taigishinkan) [see]; in 2020 it was registered in Japan as ryu-ha 流系 of kobujutsu under the International Martial Arts • Culture Federation 国際武術文化連盟 (Osaka), and Prof. Bonanno received the shikaku ninteisho certifying him as Sosetsu- sha 創設者 (Founder).
The heart of the Koyama-ryu Taigishinkan system is made up of the Okinawa Hakutsuru-ken kata (Okinawa White Crane Fist), around which all the training of the practitioner revolves which is enriched by the training of other kata, exercises and methods also deriving from more properly Japanese bujutsu, all in order to improve the skills of the practitioner himself and his culture at 360°. The Koyama-ryu Taigishinkan, in fact, also contemplates a wide arsenal of Japanese jujutsu techniques, strongly interconnected with the Okinawan tuite, characterizing the aptitude of the practitioner to fight in the body-to-body distance.
The budoka thus has the possibility of practicing only the Hakutsuru-ken, or the whole system in its entirety, or part of it i.e. a specific style (ryu-ha) pertaining to the Taigishinkan (see below).
