Patrick McCarthy, Hanshi (guest in Episode 1 of The Applied Karate Show) has posted a short (3 minute) video introduction to the International Ryukyu Karate Research Society, a style-agnostic society of karateka interested in researching the foundations of Okinawan karate.
I’ve been a member of the IRKRS for many years now, and can thoroughly recommend membership in the Society for all interested in learning more about the origins and foundations of the arts they study.
