The group released its first single, "Koa sannin musume" (興亜三人娘, "Three Girls Revitalizing Asia"), in December 1940, under the Nippon Columbia (Columbia Japan) label.[1][2] The track is a Japan–Manchuria–China friendship song, sung by all three girls in the major key.[1] The song's lyrics describe each culture as its national flower, chrysanthemum for Japan, orchid for Manchuria, and plum blossom for China.[1][3] The B-side track was "Kokoro ni saku hana" (心に咲く花, "Flowers Blooming in My Heart"), a ryūkōka sung by Ri Kōran, also about the three girls.[1] On the album cover, each girl is depicted wearing her respective national costume while holding flowers and smiling. Slightly below them on the cover is a male Imperial Japanese pilot.[1]
The group disbanded in 1941, shortly after releasing a re-recorded version of the single.[1] One of the group's members, Ri Kōran, went on to have a successful career as an actress, journalist, and politician.[4] Despite its short run, Three Girls is credited with inventing the "marketing strategy where each member takes up a unique 'official position' in the group", still used by many idol groups in the modern day.[1]
