Kawakami hails from Ashiya City in Hyogo Prefecture, and was selected as the 36th champion in the long-running talent TV show, "Star Tanjo"（スター誕生...A Star Is Born) in 1981. Making her way up to Tokyo, she made her debut in July 1983 with "Blue Etranger"at the tender age of 15. The lyrics were by Yoshiko Miura（三浦徳子） who had written a number of songs for Seiko Matsuda（松田聖子）, and the music was by Takashi Takao or Takashige （高生鷹）; can't be quite sure of the reading of the kanji.
I have to say that Kawakami's singing is surprisingly well-assured for a teenage aidoru debut, and the arrangement is quite polished....the song sounds as if it were being made for someone like Mariko Takahashi（高橋真梨子） or Seiko Matsuda at that time in her career. However, Kawakami's career would finish by 1985 with only 5 singles released. Currently, according to J-Wiki, she's a piano teacher and has a side job as a professional emcee in the Kobe/Osaka area.
