In a February 9, 2023 interview with the game's producer Yutaka Fukaya published on the Siliconera website, he was asked how he chose which costumes to include for the cast in the game since the Fatal Frame series is known for its costume selection? He responded that they gathered a wide range of ideas from within the team, picked the best ones, and then producer Fukaya made the final decision. He also stated that there were some that fit the main characters' image and others that would provide a different feel, so they hoped the players would enjoy them all.
