Nomura considers Yoshitaka Amano one of his biggest inspirations when doing artwork. His four "seniors" Hironobu Sakaguchi, Yoshinori Kitase, Hiroyuki Ito and Tetsuya Takahashi were also described as major influences. He even compared Sakaguchi to something "like a godly figure" during his early days at Square. At that time, Nomura was also taught the basics of game design by Ito. He told Nomura never to stick to existing concepts but rather to reuse just specific ideas and explained concepts such as ease of control and effortless accessibility of magic spells. Ito's work as a battle system designer inspires Nomura when thinking of the gameplay system for the Kingdom Hearts games. When designing characters, Nomura wants their names and outfits to be related with their personalities. An example occurs in Final Fantasy X where the protagonist Tidus was given a colorful uniform in order to reflect his cheerful personality and to contrast with the previous moody Final Fantasy characters. His name as well as Yuna's, another character appearing in the game, also have a common theme, the former being Okinawan for "Sun" and the latter Okinawan for "night". Various characters such as Squall Leonheart and Lulu are given multiple accessories, making the games more challenging for the programmers. When directing Advent Children, Nomura explained how the film was different from Western films due to the lack of direct answers from the plot. He added that he wants viewers to interpret certain scenes themselves and then discuss them with friends as another way to enjoy the film. The same occurs within the Kingdom Hearts series where the scenes that show unknown characters are left to the player's imagination until the following scene reveals it.
