Karate is included in Olympic Games 2020! But, not in 2024 Olympics.
There is a serious problem with quality of judging of Karate Kumite (Sparring) tournaments: Unclear Rules of competition.
Rules can be found here https://www.wkf.net/pdf/rules/wkf-competition-rules-2019_en-pdf-en-764.pdf . Despite pages and pages of instruction, there is fair amount of subjectivity. The phrases like, “Zanshin is that criterion most often missed when a score is assessed” do not help in lending the objectivity.
