Yamazaki was the only director for "Dual Destinies". When he was finished with "Dual Destinies", he became very tired of working on "Ace Attorney" games and he wanted to stop working on those games. Eshiro wanted him to continue working on the games. Eshiro brought Yamazaki to a press conference in Taiwan and the San Diego Comic-Con. This was so that Yamazaki could meet with the media and fans of the series.
