All Membership Applications will be evaluated by OKGI.  This is the first step in affiliating with our OGKI family.

You can become a member to gain access to either Goju Ryu Karate or Ryukyu Kobujutsu or both.  It is your choice.

OGKI will review your group and its activities and if necessary Murray Simpson Shihan may discuss your affiliation with senior instructors within OGKI.  A determination will then be made as to whether or not the application for affiliation should be approved, initially as a Temporary Membership.  Upon approval the Certificate of Affiliation will be sent from OGKI to you initially in electronic form until such time the formal certificate can be presented in person.

Our document Registration With OGKI contains general information about the Registration process.  Please feel free to contact us if you have any questions or concerns.

The Affiliation Fee with OGKI is listed on the Application Form.

In consideration of different economic conditions of different countries we have a two tier fee structure.  If any prospective member or affiliated member has difficulty paying the required fee the amount payable can be reduced for financial hardship reasons.


Membership of OGKI is open to all types of traditional Goju Ryu Karate do organisations or other martial arts organisations in general if they just wish to focus on Kobudo.  This includes commercial, educational and government entities.  Members may be either for profit or not for profit organisations.  All members are expected to uphold the highest standards of training and conduct as expected by OGKI.


The steps an organisation/dojo needs to follow for applying for membership are:

  1. Fill out an Application Form and have it signed and dated by an individual having appropriate authority in your organisation.
  2. Arrange payment of the Application Fee and the Registration Fee which must arrive within 30 days of the Application Form. The amounts payable are included on the Application Form.
  3. Email (or send by Messenger) the Application Form to OGKI, or directly to Shihan Murray Simpson.



Your application will be processed by Murray Simpson Shihan personally.  Before your organisation will be accepted as a full member in OGKI, a Temporary Membership may be granted for up to 12 months.

During the Temporary Membership period your organisation must invite Murray Simpson Shihan and/or another OGKI representative to a seminar organised by one of your organisation dojo.  This is required by OGKI in order to fully evaluate the quality of training being given in your organisation.  Murray Simpson Shihan may waive the need to visit an organisation or dojo if it is already known the standard of instruction being provided is of a high standard.

It is OGKI’s preference to provide support and implement a training programme to improve the standard of instruction if it is found that the quality of training within an organisation is below expectations, rather than reject applicants. 

OGKI’s focus is to promote and preserve traditional Okinawan Goju Ryu Karate do and Ryukyu Kobujutsu, accordingly OGKI accepts there will be occasions when groups may not have had the benefit of quality instruction in the past.  An organisation must therefore be willing to make suggested changes in order to improve the standard of instruction being provided.  If an organisation, after being given time, fails to improve the quality of training being given then OGKI may terminate that organisation’s membership of OGKI.

  1. Recognition of past and current Goju Ryu Karate do achievements
  2. High standard of training and support
  3. Periodic seminars and clinics
  4. Internationally recognised Dan Grading, including where necessary facilitating Dan Grading in Okinawa.
  5. Being part of a respected international group that prides itself on providing quality instruction in the art of traditional Okinawa Goju Ryu Karate do and/or where appropriate traditional Ryukyu Kobujutsu.

OGKI is dedicated to the promotion and preservation of traditional Okinawa Goju Ryu Karate do and Ryukyu Kobujustsu.  Only applicants who are dedicated to promoting and preserving either one or both of these Okinawan martial arts to a high standard will be accepted.
