千本桜 (Senbonzakura) is among the most widely recognized Vocaloid songs in the world, composed by 黒うさP (Kurousa-P) and sung by Hatsune Miku. Originally uploaded to Nico Nico Douga in 2011, it became an internet phenomenon for its galloping rock beat, rapid-fire lyrics, and a music video steeped in Imperial Japanese visual motifs, including the Rising Sun Flag. That imagery would go on to define the song's unusual availability across rhythm game regions. In maimai, Senbonzakura was added at the launch of maimai PLUS on December 13, 2012, placing it among the earliest Vocaloid tracks in the series. It carries two distinct chart families: the original Standard charts (Expert designed by ニャイン, Master by はっぴー) and a later DX chart set introduced with maimai でらっくす in July 2019 (Expert by 小鳥遊さん, Master by Jack). The DX update also swapped the jacket art and replaced the in-game PV from a dancer performance to the original animated music video by 三重の人 and 一斗まる. The DX MASTER chart totals 666 notes, a count fans occasionally remark on given the song's martial weaponry and apocalyptic lyrical undercurrent, and sits at level 12 with a constant of 12.5. The Standard MASTER chart reaches level 13 (constant 13.4) after multiple upward revisions across game versions, rising from an initial level 9 at maimai PLUS launch. Senbonzakura has never been officially released outside Japan in any SEGA rhythm game. It was one of only two songs omitted from the Chinese version 舞萌, and was removed from Asian-region maimai DX cabinets. It also appears in CHUNITHM and オンゲキ, always restricted to Japanese region releases.
