Jason Armstrong Shihan lived with a karate master in Japan and was awarded the title of Shihan in Shito-ryu in 2007. He has authored a number of karate books & has studied Japanese martial arts since 1983. From the beginning of his training , Shihan Jason Armstrong, Ph.D. and 7th Dan Jason had been taught by instructors that stressed the "Pen & Sword" approach as the end goal of the martial arts. In his time he has lived in Japan and in his early karate years, he placed at national and international kumite & kata events including Australian championships, Pacific championships, US championships (kumite only) and in Japan. His later years of karate have been more focused on bunkai & street fighting statistics and how that intersects with traditional shito-ryu, with a rationalized overlay of character development as the core philosophy of training.
He has cross-trained with BJJ for an extended period to explore karate theories and the MMA world and has authored 4 books on karate, including a novel textbook on evidence based practice (EBP) for martial arts, Fighting Statistics & Karate Technique Selection & Medical Outcomes.
Jason lived in two locations while in Japan, Himeji and Tokyo. While living in Himeji his training was focused across four Renbukan dojo which is a style of the Tani (Shukokai) shito-ryu lineage with blended Mabuni attributes through is head in that era, Sotokawa sensei. Jason also visited dojo of other styles in the Kyoto region regularly & he has nurtured his karate with direct Mabuni shito-ryu (Seito Shito-ryu & learnings from Sotokawa sensei). During his stint living in Tokyo, he taught shito-ryu at a gymnasium dojo local to Ueno Park ,and cross-trained with such dojo as Kyokushin Roppongi and Seto Sensei's dojo of the JKA (Shotokan). Jason received his rokudan (6th dan) in 2007 and also a Shihan title in 2007. In 2014 he was requested to physically test and received a 7th Dan from a panel lead by Hanshi John Sells (8th Dan awarded by Mabuni family).
His martial arts training began with Judo and he quickly switched to karate with the style Renbukan (a shukokai/Tani line derivative of karate), he recieved Shodan from Sensei Greg Story (a now almost lifetime resident of Japan who recived 5th Dan there in 1985). Jason also studied directly with Iba sensei & Sotokawa sensei of the Renbukan style in Himeji Japan. All-in-all, Jason spent 17 continuous years in the Renbukan system with dojo(s) in Australia, the USA and Japan. During most of that time the head of Renbukan was Sotokawa sensei, from whom Jason received direct training.
In 1997 Jason established a Traditional Japanese Karate Network to allow cross-training and support for his students testing for Dan ranks. This group consisted of supporting sensei across the styles of Shito-ryu, Goju & Shotokan. That network exists today and remains as not a style, or single badged organization, but as a linked group of different dojo who network through belts tests, camps and cross-teaching. The website www.Downloadkarate.com acts as a repository of information on traditional karate for the network and as a communication/resource hub for karate-ka of any organization.
