FLOWER is a high-energy electronic dance track composed by DJ YOSHITAKA (Yoshitaka Nishimura) of Konami Amusement, best known for his extensive body of work across the BEMANI rhythm-game series. It first bloomed in 2011 as part of the cross-title APPEND FESTIVAL event, debuting simultaneously in jubeat knit APPEND and REFLEC BEAT. The track was later selected as Konami's representative entry for the Tenkaichi Otoge Festival (天下一音ゲ祭), a nationwide arcade rhythm-game tournament that brought together titles from multiple publishers, through which it was ported to maimai ORANGE on October 29, 2014. Characterized by its driving 173 BPM beat, punchy synth hooks, and stadium-anthem progression, FLOWER became one of the most widely licensed BEMANI compositions of its era, appearing in every then-active BEMANI title and numerous third-party rhythm games. In maimai, the song is particularly remembered for its chart-level tributes to its Konami roots: the EXPERT chart totals exactly 573 notes, a direct numerical reference to the company's famous goroawase reading (コナミ = 5-7-3), and incorporates slide patterns that trace the letters Y, S, T, and K, spelling out the composer's alias. The song underwent multiple level revisions across maimai versions, and a Re:MASTER chart was added nearly eight years after the original release, on July 29, 2022, designed by 小鳥遊さん.
