The Shioda International Aikido Federation (SIAF) was founded by Yasuhisa Shioda, the third son of Gozo Shioda, who was the founder of the Yoshinkan style of Aikido.
Gozo Shioda trained for many years under Aikido's overall founder, Morihei Ueshiba, and he became one of Ueshiba's most accomplished students. During his training, Shioda came to understand Aikido as Budo and as an art of harmony and self-cultivation. Eventually he opened his own dojo, the Yoshinkan, of which he became kancho, and his effort was to translate the principles and teachings of Aikido into actual practice.
Shioda Kancho's grand hope was that the teachings of Aikido would be made available to people throughout the world. With the formation of the SIAF, Yasuhisa Shioda is dedicated to ensuring that his father's hope becomes a reality, and that is the SIAF's mission.

Yasuhisa Shioda(SIAF President,Soke)
Yasuhisa Shioda Shihan is the SIAF's chief instructor. He has trained in Aikido for nearly 50 years, having begun daily Aikido practice at age 13 under the teaching of his father, Gozo Shioda Kancho at the Yoshinkan Aikido Honbu Dojo. As he matured, he began to help his father promote the Yoshinkan style by teaching it in universities and to police departments and various other organizations. Eventually, he began to travel around the world, widely spreading the principles and techniques of Aikido. Among his ventures was a three-year residency in London, England where he came to realize that Aikido extends beyond the technical to consideration for others and to the spirit of candor and openness.
When Gozo Shioda passed away in 1994, Yasuhisa Shihan took up the challenge of keeping his father's legacy alive through teaching and writing about Aikido. For nearly four decades, he has traveled throughout several continents and has helped aikidoka refine and improve their practice of the art. Additionally, he has co-authored with his father the instructional manual titled "Aikido--The Complete Basic Techniques," and has authored an informative "Afterword" to Gozo Shioda's book, "Aikido--My Spiritual Journey."
With his recently launched SIAF, Yasuhisa Shioda Shihan brings structure to his father's mission of promoting Aikido worldwide and offers to aikidoka everywhere the opportunity to realize the spirit of Budo.
In accomplishing this mission Yasuhisa Shioda Shihan is delighted to be working with aikido instructors around the world.
