Written by Masao Urino and Hiroaki Serizawa, the single was released on July 28, 1982 by Warner Pioneer through the Reprise label.

[1][2] "Shōjo A" was the first hit single penned by Urino, who made his debut in 1981 with Chanels' "Hoshikuzu no Dance Hall" (星くずのダンス・ホール, Hoshikuzu no Dansu Hōru, "Stardust Dance Hall").

The lyrics were based on those from an abandoned song titled "Lolita" (ロリータ, Rorīta), which was to have been recorded by Kenji Sawada.

Urino drew some inspiration from Momoe Yamaguchi's 1978 single "Playback Part 2".

In 2010, she re-recorded the song for the pachinko machine CR Nakamori Akina: Utahime Densetsu ~Koi Moni Dome nara~ (CR中森明菜・歌姫伝説〜恋も二度目なら〜, CR Akina Nakamori: Utahime Legend ~If Love Is For the Second Time~).
