Ninja-Fu is a unique distillation of techniques from many Martial Arts disciplines including Karate, Judo, Ninjitsu, Kung-Fu, and weapons training. It was created by Grand Master Soon-Ho Chang and the first class was taught in late 1985.

Ninja-Fu is designed specifically to answer the needs of modern society. The various techniques taught are selected to provide well-rounded training for both physical and mental development. Additionally, the techniques are taught in a traditional style so that the student may learn the self-discipline and dedication that traditional Martial Arts provide.

Ninja-Fu is an excellent study for those wishing to learn Martial Arts as a means of self-defense. Because of the effectiveness of these techniques and the maturity required to handle them, no students under 16 years of age will be admitted. Also, all Ninja-Fu students must be personally approved by Grand Master Chang.

 Grand Master Soon-Ho Chang was born of a family with a strong Martial Arts tradition. He received his first degree Black Belt at the age of twelve and Black Belt degree in Judo at sixteen. After the Korean War he was admitted to the prestigious "Korean Judo College"--a professional Martial Arts College--where he received a Bachelor of Arts degree, with distinction, in physical education. He graduated with Master Instructor degrees in Jungol-Sa (Ancient Chiropractic Way), Judo, Karate, Tae Kwon Do, Hapkido, and Kendo (sword). He is the creator of both Ninja-Fu and The T.K.A. System. T.K.A. is a distillation of the best techniques from Tae Kwon Do, Karate, and Aikido styles.
