jujutsu_indonesia said:Most dominant is just two.. JKA Shotokan and Shotokai.
JKA Shotokan is the mother of 99% of all Shotokan dojos in the world. After all, Shotokan was NOT founded entirely by Funakoshi, in fact it is more correct to say that Shotokan was founded by his students, most prominent being Mr. Nakayama. It was HE who was the true founder and creator of Shotokan as we know today.
Shotokai (www.shotokai.com) is much closer to the original teachings of Mr. Funakoshi.
We also have the ITKF (International Traditional Karate Federation) which swore its allegiance to Mr. Nishiyama, another big-guns Shotokan shihan.
And lastly we have SKIF, Shotokan Karate International, founded by Kanazawa shihan, who received his 10th Dan from the prestigious Kokusai Budoin/IMAF in Japan.
