San Fransokyo is the fictional city in which the 2014 Disney animated feature film Big Hero 6 takes place and is the home of the titular heroes. San Fransokyo is an alternate history San Francisco, created after the 1906 earthquake.


The layout of the city is a futuristic hybrid of artistic and technological architecture and a blend of both San Francisco and Tokyo architectural styles. Built on the coast of the Pacific Ocean, the city is designed to withstand the risk of earthquakes. The city is also a center for vast cultures besides the dominant Eastern and Western themes. However, behind the bright aesthetic is the underworld of illegal bot-fighting, commonly located in the dark, grungy alleys of the city. A large quantity of the buildings and technology in the city were constructed by Alistair Krei and his company, Krei Tech.

  • The name and layout of the city is a mix between real-life cities San Francisco and Tokyo.
  • According to Scott Watanabe, San Fransokyo is set in an alternate future where after the 1906 earthquake, San Francisco was rebuilt by Japanese immigrants using techniques that allowed movement and flexibility in a seismic event. After the city was finished being rebuilt, it was renamed San Fransokyo due to it being a city with Japanese and American architecture combined.
