1995 ITKF rules are probably identical to JKA rules since ITKF is Nishiyama sensei. AAKF I think was the first JKA presence in the US, then it split when Okazaki sensei formed ISKF, then AAKF left JKA and became ITKF.
Meanwhile, Mr. Mori runs Shotokan Karate Do America which is now Shotokan Karate Do Internation a/k/a JKA of New York.
What distinguishes JKA kumite from AAU or WKF kumite may not be so much as the rules as the judges. JKA judges are very conservative, rarely are kicks to head awarded!
How do AAU rules or WKF rules differ?
