Also commonly referred to as Kyon Kyon, Kyoko Koizumi is somewhat of an anomaly. Like a lot of contemporary Japanese actresses, Koizumi first entered the public's eye as an idol, dabbling in careers in music, modeling and movies in the early 1980's. Her first role in a major motion picture came in 1983, which she followed up with several other theatrical projects including the critically acclaimed Mysterious Robber Ruby (1988). Unlike other Japanese idols, though, Koizumi's popularity didn't wane with age as she continued to star in movies and make headlines into the next decade. In 1995 the actress agreed to a high-profile marriage with fellow actor Masatoshi Nagase, an event which many predicted would finally mark the end of her stardom. However, it was not to be, as Koizumi continued to work in both the music and movie industries, once again making headlines when she portrayed the villain Manami Hyuga in the box office smash Bayside Shakedown (1998). Unfortunately, her career outlasted her marriage to Nagase, as the pair split in 2004.
