 Besides rank exams, many JKF tournaments also require the performance of 'Shitei Kata' (designated kata) in the first and second rounds, selected from a defined list that all examiners and judges should be familiar with.For each of the main four styles there are two kata to choose from in the first round (the 'daiichi shitei kata') and second round (the 'daini shitei kata') of any compliant tournament.On April 2, 2016, the JKF officially appointed Shin Koyamada, a Hollywood actor, producer and martial artist as the "Karate Ambassador" at the headquarters in Tokyo, Japan.
