Onizuka began boxing in middle school, entering a local boxing gym to begin training. He won several high amateur boxing tournaments in high school, but lost a match in his senior year against Hiroshi Kawashima, who would later win the WBC Super Flyweight title. Onizuka had already been accepted to Kinki University, but decided to turn pro after being battered in a sparring session with Hiroki Ioka, who had just become the WBC Minimumweight champion. He entered the Kyoei boxing gym in Tokyo, and made his professional debut in 1988 as a flyweight.Onizuka quickly built up his record, and won the Japanese Super Flweight title in October, 1990, which he defended three times before moving on to challenge the world title. His first world title match came in April, 1992, fighting Thanomsak Sithbaobay for the WBA Super Flyweight title, which had been vacated by legendary Thai boxer Khaosai Galaxy. Onizuka won a close 12 round decision, the first of the series of controversial wins in his career. Akinobu Hiranaka also won the WBA Super Lightweight title in Mexico the same day.
