Overview

鼓動 (Kodou) is a maimai track composed by Chihiro Aoki, drawn from SEGA's Japan-exclusive PlayStation 3 and PlayStation 4 title Ryū ga Gotoku Ishin! (龍が如く 維新!), a historical spinoff of the Yakuza franchise set in 1860s Kyoto. In its source game, the piece appears within a Japanese dance (日本舞踊) mini-game, lending it a restrained, period-appropriate atmosphere at 121 BPM. The track arrived in maimai on February 26, 2014, as part of the GreeN PLUS update, the first major content expansion of the GreeN arcade generation. Over the arcade series' lifetime, its in-game genre classification shifted several times: originally filed under GAME, it was moved to SEGA in PiNK, reclassified as ORIGINAL in the DX release, and finally settled under GAME & VARIETY from DX PLUS onward. The song's charts were handled by two notable designers: mai-Star laid out the 10+ Expert, while 譜面-100号 (Fumen -100 gou) authored the 13 Master. In Asian English releases of maimai, the song is displayed as KODOU - move on - with the artist romanized as Chihiro Aoki「Ryu ga Gotoku Ishin!」.

Trivia

  • 鼓動 originates from SEGA's Ryū ga Gotoku Ishin! (龍が如く 維新!), a Yakuza franchise spinoff that reimagines series characters in a Bakumatsu-period setting. The song is used within the game's Japanese dance (日本舞踊) mini-game.
  • The track was added to maimai at the launch of the GreeN PLUS update on February 26, 2014, making it one of the earliest licensed SEGA crossover songs in the arcade series.
  • In Asian English releases of maimai, the song's title appears as KODOU - move on -, and the artist is listed as Chihiro Aoki「Ryu ga Gotoku Ishin!」.
  • The Japanese title 鼓動 (Kodou) translates to 'heartbeat' or 'pulse,' which fits both the steady 121 BPM tempo and the dramatic period setting of Ryū ga Gotoku Ishin!.

  • Unlike many modern maimai DX songs, 鼓動 has no Touch notes on any difficulty, as it predates the DX hardware revision that introduced the Touch sensor panel.
  • The Master chart features a notably high Slide note count (75) for its era, giving it a flowing, dance-like quality that mirrors the Japanese dance theme of the source mini-game.
