Funakoshi Okinawan Karate Kenpō Kenkyūkai
The Funakoshi Okinawan Karate Kenpo Kenkyukai (Research Society & Study Group) is dedicated to studying and researching, in particular, Master Gichin Funakoshi's Okinawan Shorin-ryu karate kenpo teachings. For authoritativeness, Master Gichin Funakoshi's old Okinawan karate, his later developed karate, Master Gigo Funakoshi's karate, the developments of Shoto-kai, & every other karate kenpo lineage, are all considered.
