In a 2005 interview with the game's producer Koji Igarashi published in the official Konami strategy guide, he explained the decision to change the series' title in the domestic Japanese market from "Castlevania" back to "Akumajo Dracula".

The title change to Castlevania in Japan initially occurred because the Akumajo Dracula games enjoyed a larger market share in Europe and America compared to Japan. Consequently, more reports and information about the games were available in those regions, and they were released there first. In the recent past, news from outside Japan was harder to access, but with the advent of the internet, Japanese users could now easily stay informed. However, there was a concern that Japanese players might not immediately recognize the equivalence between Castlevania and Akumajo Dracula, so the main title of the previous game Lament of Innocence was changed to Castlevania in Japan to address this.

Subsequently, for Curse of Darkness, the decision was made to revert to the original title because the team felt that the Castlevania name had become associated with trilogies, inadvertently making it challenging for fans to find information about the Akumajo Dracula titles. The team wanted to ensure clarity for Japanese fans and clear up any confusion among Akumajo Dracula fans about if Castlevania was supposed to be Akumajo Dracula.
