initial idea for Kingdom Hearts began with a discussion between Shinji Hashimoto and Hironobu Sakaguchi about Super Mario 64. They were planning to make a game with freedom of movement in three dimensions like Super Mario 64 but lamented that only characters as popular as Disney's could rival a Mario game. Tetsuya Nomura, overhearing their conversation, volunteered to lead the project and the two producers agreed to let him direct. A chance meeting between Hashimoto and a Disney executive in an elevator (Square and Disney had previously worked in the same building in Japan) allowed Hashimoto to pitch the idea directly to Disney.

In June 2013, Nomura stated the name of the game came from him thinking about Disney Theme Parks, especially Animal Kingdom. However, Nomura could not get the IP with just "Kingdom", so the development team began to think about "heart" as a core part of the story, so they decided to combine the two to form "Kingdom Hearts". Nomura placed a secret trailer in Kingdom Hearts in hopes that fans would want a sequel. He was unsure if fans would want a sequel and felt that if they did not, then it would be best to leave certain events in the first game unexplained. After Kingdom Hearts Final Mix was completed, development for Kingdom Hearts II began. There were several obstacles to clear before development could begin on a sequel. One was the development team's desire to showcase Mickey Mouse more; Mickey's inclusion in the first game was restricted to a very small role. Nomura had
