Rhythm Tengoku (リズム天国 Rizumu Tengoku, lit. Rhythm Heaven) is a rhythm game developed by Nintendo SPD and published by Nintendo. It was released on August 3, 2006, and was the last game developed by Nintendo for the Game Boy Advance. An arcade version of the game was reprogrammed and published by Sega on September 20, 2007. Both versions were released in Japan exclusively. The game has spawned three sequels; Rhythm Heaven, Rhythm Heaven Fever, and Rhythm Heaven Megamix. It began as an idea created by its composer and supervisor Tsunku who proposed it to Nintendo due to his belief that they could do a better job with it than he could.
