Kingdom Hearts director Tetsuya Nomura has confirmed that Pixar's Coco will feature as a world in the upcoming Kingdom Hearts 4, explaining that he chose the Day of the Dead-inspired film because he felt it "would be the best world" for protagonist Sora's ongoing story. The inclusion continues the series' long-standing format of blending original Kingdom Hearts characters and lore with worlds drawn from Disney and Pixar properties.

Coco, the 2017 Pixar film centred on Mexican culture, music and the Land of the Dead, would mark a distinctive addition to the Kingdom Hearts roster of Disney-inspired settings. Specific details on gameplay, story integration or a release date for Kingdom Hearts 4 were not included in the available report.
