The SKDIA places great importance on bunkai, which involves the practical applications of kata, and full contact kumite is also an integral part of the training.
Nihei's vision for the SKDIA is to preserve the original teachings of Gichin Funakoshi and a realistic approach to self-defense aspect of karate.
The SKDIA has members in over 30 countries and is known for its strict adherence to traditional training methods and pushing students to reach their full potential.
