JKA has 862 branches and affiliations in Japan with more than 40,000 members. It is the largest “shotokan” karate-do organization with branches in most countries around the world. Although JKA cooperates with the Japanese Karate Federation (JKF), we pursue traditional “budo” karate rather than the so called “sport karate.”
