Kyokushin kaikan is a style of stand-up, full contact karate, founded in 1964 by master, Masutatsu Oyama.
Kyokushinkai is Japanese for "the society of the ultimate truth". Kyokushin is rooted in a philosophy of self-improvement, discipline
and hard training.
Kyokushin has influenced many of the "Full-Contact" schools of karate, emphasizing realistic combat, physical toughness, and practicality in its training curriculum. The Knockdown karate competition system pioneered by Kyokushin has been adopted by many different karate styles and organizations.
Over the years many other styles have developed
from their Kyokushin ancestry.
