"Another notable demonstration was performed by Takayuki Kubota (founder of Gosoku Ryu, Kubotan, International Karate Association). On 2 August 1964, he was invited by Ed Parker to give a demonstration at Parker's First Annual International Karate Tournament in Long Beach. Kubota began his demonstration with beating his own hands and feet with a sledgehammer. At the end he sparred with three of finalists of that year's black belt division, including Tonny Tulleners and Chuck Norris. The five-foot, five-inch Japanese faced each of three taller Americans. He took the three fighters on individually, and then all three at once. Norris was apparently so impressed that he later trained under Kubota.
