The emblem of the JKA is called Inyo.
The white and red circles represent the Japanese Yin-Yan.
The Kanji at the bottom means "Kōeki Shadan Hōjin Nihon Karate Kyokai" (public-interest incorporated association Japan Karate Association) approval received from the Japanese Ministry of Education in 1957.
