The All-Japan Kickboxing Association, for which Suzuki had been rated as No. 2, became interested in the American sport of full-contact karate, decided to promote series of mixed-rules bouts between the American full-contact karate fighters and Japanese kickboxers. On November 14, 1977, the AJKF held the first of such event which featured Benny Urquidez, his brother-in-law Blinky Rodriguez, Marc Costello, Brendan Leddy, Tony Lopez, Leonard Galiza and Freddy Avila. Only Benny Urquidez and Costello came out as the winners for the American team. Urquidez's victory over Kunimitsu Okao convinced the Japanese fight fans, and eventually began to be featured as the central figure for what was supposed to be the documentary comic book, "The Square Ring", until he declined to avenge his loss against the Thai opponent Prayout Sittiboonlert. Urquidez's second loss came in August 1980 in Florida. American Billye Jackson dominated seven rounds including knocking Urquidez down. Urquidez protested the decision and petitioned the WKA's Howard Hansen to classify it as a non-contest.
