Group Membership Application Procedures All Group Membership applications must be evaluated and approved by Tokyo JKA HQ. The first step in affiliating your group with the JKA is to contact us at sohonbu@jka.or.jp. The headquarters office will review your group and its activities and discuss your affiliation with the National and/or Regional JKA head- quarters. Together they will make a determination as to whether or not the affiliation should be approved. Upon approval, notification will be sent from the Tokyo JKA HQ to your group as well as to your National and Regional headquarters. When you receive such notification, please contact your nearest authorized JKA representative, who will provide you with information on the next steps.
