Kaori Yoneyama (born February 26, 1981) is a Japanese professional wrestler, currently working as a freelancer on the Japanese independent circuit. She operates the independent promotion Gokigen Pro Wrestling, succeeding YMZ Pro Wrestling, which closed in 2025. She is perhaps best known for her appearances in World Wonder Ring Stardom under various gimmicks and names, most recently as Fukigen Death, a member of the H.A.T.E. stable. She also appears for various other promotions, such as ChocoPro (previously Gatoh Move Pro Wrestling), OZ Academy, and Pro Wrestling WAVE. Yoneyama started her career in 1999, working with the JWP Joshi Puroresu promotion. During the following years, she became a one-time JWP Openweight Champion, a one-time JWP Junior Champion, a five-time JWP Tag Team Champion and a three-time Daily Sports Women's Tag Team Champion. Notable titles she has held outside of JWP include All Japan Women's Pro-Wrestling's AJW Championship and AJW Tag Team Championship, Ice Ribbon's International Ribbon Tag Team Championship and NEO Japan Ladies Pro Wrestling's High Speed Championship. In July 2011, Yoneyama announced that she would be ending her twelve-year career the following December. After a retirement tour, which took Yoneyama not only across the Japanese independent circuit, but also to the United States, she announced during her retirement ceremony that she had changed her mind and decided to continue her career, which caused considerable scandal and notoriety.
