Best is the first Japanese compilation album and sixth overall album release by Mika Nakashima. It contains 14 songs. Two new re-recordings were made: one of her first single, 'Stars,' and the other of 'Amazing Grace (05),' the latter of which was included in a Suntory commercial for Freixnet Champagne and made as a radio-only single to promote the album in Japan. Best debuted at #1 in the Japan Oricon 200 Album Chart when it was released, selling 480,097 copies in its first week – bettering the first-week sales of her first album, True. It was the #5 album of 2006.
