Kita Saitama 2000 (きたさいたま2000) is a high-tempo crossover track by LindaAI-CUE (Tetsuhiko Ishikawa), a Bandai Namco composer known for his offbeat, geography-themed "2000 series" of songs for the Taiko no Tatsujin franchise. Brought to maimai as part of the first Tenkaichi Otogesai (天下一音ゲ祭) inter-arcade event in 2014, the song runs at a blistering 222 BPM and clocks in at exactly 2:00, the sixth entry in a series that began with the iconic "Saitama 2000." The lyrics are a love letter to the now-defunct Kita Saitama District (北埼玉郡) of Saitama Prefecture, chanting the names of its three former towns, Otone (大利根町), Kitakawabe (北川辺町), and Kisai (騎西町), alongside the neighboring prefectures of Gunma, Ibaraki, and Tochigi. Interwoven with spoken census data ("the population as of 2005 is nearly 52,000 people…") and Morse code messages embedded in triangular brackets, the track fuses trivia-like narration with a relentless energy that defines the 2000 series ethos. A slower arrangement titled "Kita Saitama 200" later appeared in Taiko no Tatsujin 13. In maimai, the song debuted in ORANGE on October 29, 2014 as a Qualifying Round entry exclusive to AOU arcade locations, rolling out to all arcades on February 16, 2015. It was simultaneously added to jubeat saucer fulfill and Groove Coaster EX, making it a true cross-ecosystem event piece. The MASTER chart, co-designed by 譜面-100号 (Fumen -100 gou) and はっぴー (Happy), was originally credited under the joint pseudonym "合作だよ" (it's a collaboration) in versions before PRiSM, reflecting the collaborative nature of its dense 840-note layout.
