Sonoko Kato (加藤 園子, Katō Sonoko, born June 11, 1976) is a Japanese professional wrestler. She made her debut in April 1995, working for Gaea Japan, where she became one half of the inaugural AAAW Junior Heavyweight Tag Team Champions. After becoming a two-time winner of the High Spurt 600 Tournament, Kato's career came to a halt following multiple injuries. After being sidelined for five years, Kato returned to the ring in October 2006, following the folding of Gaea Japan, and found a new home in the Oz Academy promotion, where she is a former two-time Oz Academy Openweight Champion and a four-time Oz Academy Tag Team Champion. Kato has also wrestled in the US for World Championship Wrestling (WCW) and in Mexico for Lucha Libre AAA World Wide (AAA).
