“I want to wish all the members a very happy and healthy New Year, and I hope this will be the year we can arrange a seminar somewhere (Hint) and all get to train together.
Thank you for your support in the past, and I look forward to ISOK continuing to grow and expand in the future.”

Do remember to send in details of events and your news for the newsletter.  Best wishes –  Vince Morris CEO ISOK.


ISOK was formed by a small group of high-ranking karate-ka with impeccable training backgrounds, each of whom was concerned at the growth of Karate schools that did not have proper credentials or training history, thus devaluing both the image and the effectiveness of the martial art of Karate.

Whilst recognizing that there would sometimes be a genuine reason why a student would break from their teacher, and possibly that school, ISOK was therefore established – much like the Butokukai in Japan – to act as a reference point for validation of rank and the accreditation of its members as legitimate holders of rank within a recognized system.

Since conception, ISOK has grown to include members on its Senior Technical Commitee from different countries around the world, and is held in high esteem by those who see the value of its continued work.

As the current chairman and CEO, I am proud to be continuing the tradition of excellence established by the founding members and I look forward to welcoming new members to our ranks.

ISOK membership is open to black belt practitioners of Karate who are 18 years of age and older.
