Superfly is a Japanese rock act that debuted on April 4, 2007. Formerly a duo, the act now consists solely of lyricist and vocalist Shiho Ochi with former guitarist Kōichi Tabo still credited as the group's composer and part-time lyricist. Superfly's first two studio albums were certified double platinum by the Recording Industry Association of Japan, and their first four consecutive albums (the third being classified as a "single" by the group) all debuted at the top of the Oricon Weekly Album Charts, a first for a female recording artist in Japan in over seven years.
