Worlds
Tour every confirmed KINGDOM HEARTS IV world, from the realistic Tokyo-inspired streets of Quadratum to the Coco world, Scala ad Caelum and the Underworld.
Introduction
The Worlds and Locations section is a tour of everything Square Enix has confirmed for KINGDOM HEARTS IV. The headline is Quadratum, a realistic world inspired by modern Tokyo where Sora wakes up and where the local population believes people from other worlds are fictional. Around it sit the Coco world based on the Land of the Dead, the glittering Scala ad Caelum where Mickey appears, and the Underworld where Donald and Goofy search for Sora. Each world profile explains its official details, its place in the series timeline and what players should expect from its design based on trailers. We keep the list strictly confirmed, adding community theories only when clearly labelled.
Confirmed Worlds
Quadratum
Sora’s new home — a realistic world inspired by modern Tokyo (Shibuya and Minami-Aoyama).
Confirmed as the opening setting and central hub; its people believe other worlds are fictional.
Coco (Land of the Dead)
Disney and Pixar’s Coco world confirmed in the D23 2026 trailer.
Officially confirmed; the trailer shows a colourful celebration and the Land of the Dead.
Scala ad Caelum
The gleaming city from the end of Kingdom Hearts III, where Mickey appears in the new trailer.
Shown again in the D23 2026 trailer with a returning Mickey; its role in the Lost Master arc is unknown.
Underworld
Donald and Goofy search the Underworld, where Hades returns as a threat.
Confirmed in the D23 trailer; the classic Greek underworld appears ahead of the Coco land of the dead.
World Profiles
Quadratum
A realistic world inspired by modern Tokyo, and the heart of the KH4 story.

Core Mechanics
World exploration in KH4 appears to combine the series’ tradition of hub worlds with a new degree of vertical movement. Quadratum is designed around realistic city streets, rooftops and urban plazas, and the confirmed parkour system lets Sora climb, leap and slide across the environment instead of following flat corridors. The grappling-hook Keyblade adds a second traversal tool, letting him swing across gaps or pull himself toward ledges. Combat and exploration share this movement vocabulary, so a player who masters parkour can approach encounters from above. Worlds like the Coco land of the dead promise denser, more theatrical spaces, while Scala ad Caelum and the Underworld reuse classic locations with new layouts. We expect each world to gate certain story progression, as the series does, but with fast-travel between previously visited areas.
Advantages
The greatest strength of the confirmed world list is its variety. Quadratum offers a one-of-a-kind realistic urban setting that the series has never attempted, immediately distinguishing KH4 from every previous Kingdom Hearts game. The Coco world brings a warm, celebration-soaked aesthetic that contrasts beautifully with Quadratum’s colder city, while Scala ad Caelum and the Underworld give returning fans nostalgic anchors. This variety also benefits gameplay: traversal challenges in an urban megastructure, open combat arenas in the Land of the Dead and puzzle-like spaces in Scala’s towers keep each world feeling distinct. For lore hunters, Scala ad Caelum and the Underworld are dense with references, and Quadratum’s “fictional worlds” theme sets up philosophical questions that should pay off across the whole Lost Master arc.
Challenges
The confirmed world list is still short, and that is the central limitation of this section. Square Enix has shown Quadratum extensively but only teased the Coco world, Scala ad Caelum and the Underworld, so most of their content remains unknown. Players who loved the huge Disney world catalogues of previous games may be disappointed by how few destinations are confirmed this far out. There is also uncertainty about how much of Quadratum is explorable: the realistic Tokyo-inspired design could mean a sprawling hub or a series of scripted districts. Until more gameplay is shown or the game launches, every world profile must rely on trailer evidence and series conventions, and we state those limits honestly rather than padding the pages with invented locations.

Quick Tips
Use Quadratum to learn parkour early because the urban environment is the perfect training ground for the movement system; experiment with rooftops, ledges, fences, staircases and slide-through alleys before combat starts demanding agility, so traversal becomes second nature from the very first moment enemies suddenly appear across the beautiful city streets.
Keep the Coco world in mind for celebration-themed content; if the film is any guide, the festival setting will reward exploration with collectibles, side characters and emotional scenes that deepen the story. Plan to revisit it once you have better Keyblades and parkour skills that let you reach every hidden path.
Revisit Scala ad Caelum with the lore pages open; the city is packed with references to Keyblade history, the Foretellers and the ancient war that reward players who know the backstory. Notice its architecture, murals and statues, because the world is practically a museum filled with hidden Kingdom Hearts secrets.
