Onyanko Club was a large all-girl Japanese pop idol group in the 1980s. Some members of the group participated in spin-off groups, such as Nyangilas, Ushiroyubi Sasaregumi and Ushirogami Hikaretai. Many of the latter two groups' songs were used as theme songs of the popular 80s anime series High School! Kimengumi and Tsuide ni Tonchinkan. Several big-name idols stemmed from the group; one of the best known being Shizuka Kudo. The group was produced by Hiroshi Ishida and Kazuji Kasai, both of whom were producers of Fuji TV's show Yūyake Nyan Nyan.

An idol is a type of entertainer marketed for image, attractiveness, and personality in Japanese pop culture. Idols are primarily singers with training in other performance skills such as acting, dancing, and modeling. Idols are commercialized through merchandise and endorsements by talent agencies, while maintaining a parasocial relationship with a financially loyal consumer fan base.
