Yoshinkan Aikido is not a sport. Aikido is the development and strengthening
of the body and mind, and the practical side of Aikido must never be
forgotten. However, Aikido is for all, irrespective of age, sex, race
In 1990, Gozo Shioda and his son, Yasuhisa Shioda, established the International
Yoshinkan Aikido Federation (IYYF).
IYAF was change to Aikido Yoshinkan Foundation (AYF) in 2008.
This international organization has become very successful in promoting
the development of Yoshinkan Aikido in countries around the world.
To all dojo representatives/members of Yoshinkan Aikido around the world:
Any dojo that is not listed under the Honbu Dojo Directory is not considered a recognized dojo by the Yoshinkan Aikido Federation.
If your dojo is not registered by the Honbu Dojo, please register as soon as possible. (AYF mail link
It is against legal rules to use the Yoshinkan Aikido name by an unrecognized dojo.
Distribution of Dan/Kyu gradings and certificates by an unrecognized dojo is also against rules, and these certificates will have nothing to do with the Yoshinkan Aikido Federation.
If you find any unregistered organizations or dojos using the Yoshinkan Aikido name or distributing grading certificates, please let the Yoshinkan Aikido Honbu Dojo know.
We will make any necessary investigations, and make the necessary actions. (AYF mail link
