Later on, though, I did get to listen to one of the tracks from "Venus Tanjo" on "Sounds of Japan". "Kuchibiru Network" (Lip Network) was one of the chirpiest and quintessentially aidoru tunes I'd ever heard by anyone. And as I had mentioned in one of the other articles on the singer, Okada struck me physically and musically as being one of the quintessential aidorus from that decade. She had the cute face, the short bob and that high wispy voice which seemed to quaver at certain points in a song.
Perhaps that aidoru-ness about her was the reason for not only for a lot of the big songwriting veterans such as Yoshiko Miura（三浦徳子）and Chinfa Kan（康珍化） to get behind her, but also a number of artists themselves such as EPO, Mariya Takeuchi（竹内まりや） and Ami Ozaki（尾崎亜美）. "Kuchibiru Network" itself has quite some pedigree behind it: Ryuichi Sakamoto（坂本龍一） of The Yellow Magic Orchestra was the composer, and the Queen Aidoru herself, Seiko Matsuda, was the lyricist. According to the writeup on the song on J-Wiki, Matsuda had some initial misgivings about her work: "I'd thought that the lyrics were just a little too sexy, but when Yukiko-chan sang them, they became a cute and charming song." And certainly when I listened to it, I never got the impression that this was anything but a cute puppy love sort of ditty with Okada singing about how impatient she was getting over who was gonna make the first move.
This one actually has Yukiko's appearance on one of the big music shows.
"Kuchibiru Network" was released as a single in January 1986 with "Venus Tanjo" getting released on March 21. It became Okada's biggest hit, reaching No. 1, and later becoming the 36th-ranked single of the year. It was also used as a campaign song for Kanebo Cosmetics. However, less than 3 weeks after the album came out, the singer would take her own life at the age of 18.
