I guess that she would be one of the last 80s solo aidoru to debut, and though Chami Satonaka（里中茶美）doesn't have the greatest voice, she has plenty of what an old Vaudevillian agent would say is MOXIE! She dances up quite the storm in her video for her 2nd single "Mahou no Beat" (Magical Beat) which came out in July 1989. Takashi Matsumoto（松本隆）wrote the lyrics about admiring her crush some tables away from her in a cafe, while Minoru Komorita（小森田実る）took care of the really peppy and perhaps Eurobeat-y sound.
A native of Okinawa and a graduate from the Okinawa Actors School, Satonaka, whose real name is Chami Hentona（邊土名茶美）, released only 5 singles up to July 1990 and one original studio album which came out in 1989. I don't know what she's doing now although according to her J-Wiki profile, she's still listed as a singer and tarento. Perhaps she may not be too well known but I have a feeling that at least some of you may know her younger brother who is the leader and vocalist of this group who has made this huge comeback this year.
