All 17 of the songs for the "Kyōiku" era were recorded over a period of four days. The song features lyrics by Sheena set to a melody composed by then band pianist H Zetto M. It was one of three songs from "Kyōiku" to be written in this style, the other two being "Genjitsu ni Oite" and "Service". The single's B-sides include a cover of the 1937 standard "The Lady Is a Tramp", and "Kao", a duet between Sheena and then guitarist Mikio Hirama, who wrote the song's music. Sheena stated that it had been "a dream of sorts" to release music that collaborated with a variety of songwriters. The single's song lengths are all palindromic, much like Sheena's album "Kalk Samen Kuri no Hana" (2003). Pianist H Zetto M gave Sheena a collection of demos before recording sessions started, and "Gunjō Biyori" was the first song present. Sheena felt as if he had written the song specifically for Sheena, and everything she was experiencing. "Kao" was a song Hirama initially gave Sheena during the "Sugoroku Tour", though she felt she could not sing it. Eventually, the idea of singing the song as a duet was created, meaning the song became feasible.
