Misono released her forth studio album, Uchi, on her 30th birthday, on October 13, 2014.

The album failed to sell over 10k copies and questions were raised about Misono's possible retirement. However, she stated that that was not the case; she would just stop releasing albums, but she would not retire from the entertainment business.

Three singles, produced by Straightener's Hidekazu Hinata, GO!GO!7188, and Onsoku Line, respectively, were released between September 2007 and January 2008. These songs were subsequently part of misono's second studio album, Say, which was released on July 16, 2008.

In 2006, Misono debuted as a solo artist with the release of her first single, "VS", which was used as theme song for Nintendo DS videogame Tales of the Tempest, following previous songs by day after tomorrow that were used in this videogame franchise. The single debuted at number 4 on the Oricon charts. During this period, misono used classical Western fairy tales as inspiration for her visuals in music videos and promotional photographs, using themes such as Snow White ("VS"), Cinderella ("Kojin Jugyō"), The Ugly Duckling ("Speedrive"), and Peter Pan for her first studio album, Never+Land, released on February 2, 2007.

In November 2007, misono became a recurrent guest in Fuji TV variety show Quiz! Hexagon II, and during these period she participated in said show's comedic units "Misono & Hiroshi" with Hiroshi Shinagawa, and "Satoda Mai with Gōda Kyōdai" with Mai Satoda and Toshifumi Fujimoto.

In 2000, Misono participated in the summer vacation audition organized by Japanese label Avex, and was subsequently chosen by the label to become one of their artists. In 2002, she debuted as the vocalist of Day After Tomorrow (dat), a J-pop band formed by the Avex Trax label under the production of Mitsuru Igarashi. Only five months after their debut, they received the Newcomer of the Year award at the Japan Record Awards.
