Development
Tetsuya Nomura was questioned during an interview in early 2010 if Birth by Sleep would receive the Final Mix treatment like Kingdom Hearts and Kingdom Hearts II before it. Nomura answered that he was interested, particularly citing his affinity for the English voice cast and their work on the English dub. However, he also voiced concern that the main reason Kingdom Hearts II Final Mix sold as well as it did was because it was part of Kingdom Hearts II Final Mix +, a privelege this game would not receive, so he and the team would continue to debate the topic.

In September of that year, Square Enix announced that Kingdom Hearts Birth by Sleep: Final Mix would release in Japan on January 20, 2011. As per tradition, the game's primary language dub was English with Japanese subtitles, and includes the content added in the international release alongside more new content.
