I know a crazy Russian Ryukyu guy near you. I teach Ryukyu Kempo close cousin to Issin ryu. I’m sorry but I have not heard of your Sensei ... I train(ed) under Taiko Oyata George Dillman and Jack Hogan (to name a few) Oh and don’t call me Shirley
You can look up Sensei Long on the net...
I also had the honor to meet Master Tatsuo Shimabuku in 1967 when he visited Harold Long...
I haven’t studied for quite a few years since I lost a leg...
I achieved San Dan rank.
