Square Enix and Disney revealed an extended 4-minute gameplay trailer for Kingdom Hearts 4 at the D23 2026 fan convention and Disney Entertainment Showcase in Anaheim on August 15, 2026 [1, 2, 3, 4, 5]. The trailer showcases key characters including Sora, Donald Duck, Goofy, and for the first time, a playable Mickey Mouse appearing in a puzzle-based Paper Mario-style world [1, 2, 3, 5].

The game introduces new worlds, such as Pixar’s Coco-inspired Land of the Dead and Quadratum, a fictionalized version of Tokyo’s Shibuya district [1, 3, 4, 5]. The story continues after Kingdom Hearts 3, following Sora trapped in Quadratum while Donald and Goofy search for him in the Underworld [3, 4, 5].

Kingdom Hearts 4 retains the series’ real-time action RPG combat and adds a new Build system alongside various traversal moves [1, 5]. Mickey Mouse gameplay segments include transformations into different forms—large, small, and paper-thin origami—that tie into puzzle-solving elements [1, 2, 3, 5].

Franchise creator Tetsuya Nomura appeared as a surprise guest during the D23 panel and confirmed the game remains on track for a late 2027 release across PlayStation 5, Xbox Series X|S, Nintendo Switch 2, and PC. Nomura said, "Kingdom Hearts 4 is still on track to launch in its late 2027 release window for PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X | S" [1, 2, 3, 4, 5]. He added the choice to include the world of Coco came because, "We felt that Coco would be the best world that would really help to achieve that" [3].

The D23 event also featured series voice actors Haley Joel Osment (Sora) and David Gallagher (Riku) performing scenes together for the first time in person [1]. New story teasers revealed interactions between Luxu (Xigbar) and a young Xehanort within Quadratum, along with hints toward the return of Maleficent [5].

Kingdom Hearts is one of Square Enix and Disney’s highest-selling collaborations, with the franchise surpassing $1 billion in retail sales to date. The series marks its 25th anniversary in 2026 [3].

The first tease of Kingdom Hearts 4 occurred in 2022, with limited details until early 2026. In June 2026, the game closed a major Nintendo Direct event, followed by a 90-second teaser trailer at the Disney Entertainment Showcase on August 14, 2026 [1, 3]. The extended trailer and panel on August 15 offered the most substantial look so far [1, 2, 3, 5].
