Golden age, decline and transfiguration of Idols

In the 1970s, the popularity of female idol singers such as Mari Amachi, Saori Minami, Momoe Yamaguchi, and Candies increased. Momoe Yamaguchi was one of the first kayōkyoku singers to use the special pronunciation characteristic of J-pop. In 1972, Hiromi Go made his debut with the song "Otokonoko Onnanoko" ("Boy and Girl"). Hiromi Go originally came from Johnny & Associates.

In 1976, female duo Pink Lady made their debut with the single " Pepper Keibu ". They released a record nine consecutive number-one singles.

In the 1980s, Japanese idols inherited New Music, though the term fell out of usage. Seiko Matsuda especially adopted song producers of previous generations. In 1980, her third single "Kaze wa Aki Iro" ("Wind is autumn color") reached the number-one spot on the Oricon charts. Haruomi Hosono also joined the production of her music. She eventually became the first artist to make 24 consecutive number-one singles, breaking Pink Lady's record.

Other female idol singers achieved significant popularity in the 1980s, such as Akina Nakamori, Yukiko Okada, Kyōko Koizumi, Yoko Minamino, Momoko Kikuchi, Yōko Oginome, Miho Nakayama, Minako Honda, and Chisato Moritaka. Okada received the Best New Artist award from the Japan Record Awards in 1984. Nakamori won the Grand Prix award for two consecutive years (1985 and 1986), also at the Japan Record Awards.

Japanese idol band Onyanko Club made their debut in 1985, and produced popular singer Shizuka Kudō. They changed the image of Japanese idols.

Around 1985, however, people began to be disenchanted with the system for creating idols. In 1986, idol singer Yukiko Okada 's song "Kuchibiru Network" ("Lips' Network"), written by Seiko Matsuda and composed by Ryuichi Sakamoto, became a hit song, but she committed suicide immediately after that.

Hikaru Genji, one of the Johnny & Associates bands, made their debut in 1987. They became a highly influential rollerskating boy band, with some of their members gaining their own fame as they got older. Their song "Paradise Ginga", written by Aska, won the Grand Prix award at the 30th Japan Record Awards in 1988. Some of the group's backing dancers later formed SMAP.

The late 1980s also saw the rise of the female duo Wink. They did not laugh, unlike Japanese idols of former eras. Wink debuted in 1988, surpassing the popularity of the then-most popular female duo, BaBe. Wink's song " Samishii Nettaigyo " won the grand prix award at the 31st Japan Record Awards in 1989.

Popular singer Hibari Misora died in 1989, and many kayōkyoku programs, such as The Best Ten, were closed.

CoCo made their hit debut with the 1989 single "Equal Romance" for the hit anime series Ranma ½. Tetsuya Komuro, a member of TM Network, broke Seiko Matsuda's streak of 25 consecutive number-ones by making his single "Gravity of Love" to debut at number-one in November 1989.
