Birth by Sleep is a prequel to the first Kingdom Hearts game, taking place ten years prior. Like the other games in the series, the player progresses through a collection of various worlds, based on various locales from the Disney animated features canon: Dwarf Woodlands from Snow White and the Seven Dwarfs; Enchanted Dominion from Sleeping Beauty; Castle of Dreams from Cinderella; Olympus Coliseum from Hercules; Deep Space from Lilo & Stitch; Neverland from Peter Pan (featuring for the first time most of the main island setting new to the series rather than Captain Hook's pirate ship and Big Ben from the first game and Kingdom Hearts 358/2 Days); and Mysterious Tower from Fantasia.

The game also features various new worlds specially created for the series by Square Enix such as the Land of Departure and Radiant Garden. Disney Town, which is the town that surrounds the castle grounds of Disney Castle, serves as the game's minigame world. Worlds such as Destiny Islands and Castle Oblivion also appear in the form of cutscenes, while the 100 Acre Wood from the Winnie the Pooh franchise, which had appeared in most other games of the series, only appears as a Command Board in Birth by Sleep.
