In Kingdom Hearts III, which world is based on Disney's Big Hero 6?

In Kingdom Hearts III, the world based on Disney’s Big Hero 6 is San Fransokyo. It combines the film’s fictional cities of San Francisco and Tokyo into a single futuristic setting created for the Kingdom Hearts universe.

Sora, Donald, and Goofy visit San Fransokyo after the events of the film and meet Hiro Hamada, Baymax, and the other members of Big Hero 6. The world’s story centers on a second, dark version of Baymax, which has been transformed into a dangerous enemy. This lets Kingdom Hearts III continue the film’s themes of technology, friendship, invention, and responsible heroism.

The other options refer to different worlds: Toy Box is based on Toy Story, Arendelle is based on Frozen, and The Caribbean draws from Pirates of the Caribbean. San Fransokyo is therefore the specific world name players see in Kingdom Hearts III, rather than simply “Big Hero 6” or “San Francisco.”
