Traditional Challenge Divisions showcase the patterns of recognized karate systems from Japan (Shotokan, Shito-Ryu, Goju-Ryu, Wado-Ryu, Chito-Ryu) and Okinawa (Shorin-Ryu, Isshin-Ryu, Goju-Ryu, Uechi-Ryu).
Competitors MUST perform a recognized unaltered/unmodified kata from one of the above systems and no additions or deletions of movements are allowed. School variations are permitted provided the movements maintain the structural integrity of the original kata.
Unlike the Japanese/Okinawan division (NASKA), competitors must only perform unmodified katas from Japanese or Okinawan Karate systems. Competitors who choose to alter/modify a classical working or add/delete moves are strongly encouraged to enter the NASKA Japanese/Okinawan division as such changes to the kata will result in disqualification in the Traditional Challenge division.
