The term KASAI in Japanese literally means Fire Storm, a term once used to describe the intense battles of medieval Japan.
Inspired by this warrior spirit, BJJ Black Belt and renowned businessman Rich Byrne founded KASAI in 2016 to revolutionize professional grappling. His vision? A stage where the world’s best athletes could go to war, just like the legendary samurai of the past. Heart. Energy. Relentless. Forged through fire. This is KASAI!
