The Japan Karate Association is the only independent karate entity legally and officially recognized by the Japanese government as an association of members (Shadan Hojin) for the promotion of karate.

There is only one other authorized entity which falls under the umbrella of the JKA: the JKA World Federation (JKA/WF). No other organization shares this status. For the most part, the JKA is centrally organized and coordinated through Tokyo JKA HQ, although there are both National and Regional headquarters in most areas around the world.
