Avex Trax hired Japanese musician Max Matsuura to produce the entire record, alongside with Hamasaki and Japanese musician Naoto Suzuki's help, while Hamasaki wrote every song on the album. Recording sessions were handled at Prime Sound Studio, Studio Sound Dali, and Onkio Haus in Tokyo, Japan, and at Soundtrack Studios in New York City, United States; the final material was then mixed at Studio Sound Dali and Conway Studios in Los Angeles, California, and mastered by Eddy Schreyer at Oasis Masterings.
