In a 2008 interview with the game's director Katsura Hashino published in the Persona Club P4 book, he credited the game's Japanese voice cast for having "saved us". He went on to explain the casting process for the Japanese version, which only started after a rough draft of the script was finished. The game's scenario writer Yuichiro Tanaka came up with a list of potential candidates and samples of their work; Hashino, character designer Shigenori Soejima, and sound designer Shoji Meguro selected the cast together from that list. Hashino noted that none of them had much knowledge about voice actors and only relied on the given samples to choose who they felt was best for the role.
