the game being released worldwide, the team decided to localise titles in multiple languages. As with the first two main Kingdom Hearts games, it has a theme song written and performed by Hikaru Utada, titled "Chikai" in Japanese and "Don't Think Twice" in English. It serves as the game's ending theme. An additional theme, titled "Face My Fears" by Skrillex, Poo Bear, and Utada, is used for the opening of the game. Skrillex, a fan of the series, originally intended to remix "Don't Think Twice", before creating "Face My Fears", which also has a Japanese version. Both "Face My Fears" and "Don't Think Twice" were released on January 18, 2019. Utada requested that the producer Skrillex produce a remix of the song "Chikai" for Kingdom Hearts III, since it was known that he was a fan of the game. He proposed to instead make a completely new song. Utada agreed to collaborate with him and songwriter Poo Bear to write the song. Voice cast Kingdom Hearts III only features English and Japanese voice acting and lip syncing, despite previous entries in the series having dubbing in other languages. Nomura noted that the development team wanted to prioritize a global simultaneous release for the game, and given the time and resources for recording the dialogue, this would not have been possible with additional language recordings. Though the game has both English and Japanese voice acting, it does not have the ability to switch between them, as the development team found this feature difficult to properly support. A version of the game with Chinese subtitles will also be released. Kingdom Hearts III has full voice acting in optional dialogue moments outside of cut scenes, which is a first for the series. In the Japanese voice cast, Akio Otsuka, the voice actor for Xehanort's Heartless "Ansem", replaced his late father Chikao Ohtsuka, who played the villain Master Xehanort. Miyu Irino returned to voice Sora and Vanitas as he faced more issues during recordings of the game. After finishing the game, Irino wondered if he might properly portray Sora in sequels due to his age gap. Mamoru Miyano also returned to voice Riku and his replica persona with similar difficulties to his more drastic age gap. Miyano reflected that Riku had to act more positive, especially when interacting with his replica, since he understood his mindset. Risa Uchida provided the voice for Kairi and
