One (Aimer song)
"One" is the thirteenth single by Japanese singer Aimer, released on October 11, 2017 under SME Records. Written by Aimer and Rui Momota, the single peaked at No. 2 on Oricon's singles charts and No. 3 on Billboard Japan's Hot 100.
Aimer debuted the song at her Nippon Budokan concert on August 29, 2017, calling it her "first dance song." She explained that "One" was a new chapter in her career after her compilation album Best Selection "noir" ended with the song "zero." The song expresses positivity and inspiration, with the "flag" as a symbol of starting over.
The single includes "Hana no Uta", "Rokutosei no Yoru Magic Blue ver.", and "Ito".
