The Children’s Cup is open to all athletes aged 6–13 years, with no limit on the number of teams per country. Participation is open to competitors from all sporting federations in traditional karate, provided they are citizens of the country they represent (proof required at registration) and compete in accordance with ITKF rules.
All Kumite, Ko-Go, and Fuku-Go athletes must wear official ETKF gloves and mouth guards; other protective equipment is optional but recommended. Each athlete must also have valid travel and accident insurance provided by their national federation.
