Ozaki debuted in a tag team match in August, 1986. In her career, she held the WWWA tag titles with Dynamite Kansai from April 11, 1993 to December 6, 1993 (both winning from and losing to Manami Toyota and Toshiyo Yamada of All Japan Women's Pro-Wrestling, selected for "Wrestling Observer Newsletter's Match of the Year for 1993". They rematched in April 1993 and won at the Dreamslam II (and with it the titles); the first time a woman's match won the award. Their final match was at St. Battle Final in December. (AJW). She also held the UWA Junior and JWP Junior titles between 1988 and 1991, and teamed with Cutie Suzuki and Hikari Fukuoka to win the JWP Tag Titles a number of times between 1992 and 1995. She held the AAAW Tag Team Championship with Aja Kong, beating GAEA's Sugar Sato and Chikayo Nagashima on August 23, 1998 in Tokyo.
In 1995 Ozaki competed at the 1995 WCW World War 3 on Pay Per View event where she teamed with Cutie Suzuki against Bull Nakano and Akira Hokuto where they lost. They also competed against the same team the very next night on WCW Monday Nitro which they also lost.
Until recently, Ozaki usually wrestled in JWP Joshi Puroresu, but was also the leader of her own heel stable called the Oz Academy, which freelanced in other women's promotions in Japan, such as AJW and GAEA. In 1998 Ozaki became a true free agent, and began to promote her own shows using her Oz Academy wrestlers, looking for a niche in the fragmented women's puroresu scene. Ozaki made her mark mostly in tag team matches as she competed in four bouts that were among the greatest ever in women's tag team wrestling, having earned a 5-star rating each by the Wrestling Observer Newsletter.
In December 2011, Ozaki took part in American promotion Chikara's JoshiMania weekend, teaming with Mio Shirai in a losing effort against the team of Cherry and Ayako Hamada on night one on December 2. The following day, Ozaki defeated Shirai in a singles match. On the third and final night of the tour, Ozaki defeated Kaori Yoneyama in another singles match.
