Force is the fourth studio album by Japanese pop-rock unit Superfly. It was released on September 19, 2012. Force commemorates the group's fifth anniversary and was released in several formats, including a special fifth anniversary edition which includes a bonus CD (included with the first-press releases), a vinyl version of the album, and a commemorative poster. Japanese convenience store Lawson will also exclusively sell a special edition of the album which includes a bonus DVD. On the iTunes Store, the album will be packaged with one bonus track, with a second reserved for those who pre-ordered the album.

The album's title comes from both the English word "force" as well as the similarity between the Japanese pronunciations of "force" and "fourth".

To support Force, Superfly is going on two separate tours, the "Live Force" national concert hall tour from October 2012 through January 2013 and the tentatively titled "Superfly Arena Tour 2013" in March and April 2013.

Force sold 119 thousand copies in its first week of sales, making it Superfly's 5th consecutive album to debut at number 1 on the Oricon charts, and placing her with Namie Amuro, Mai Kuraki, and Hikaru Utada as female solo artists with 5 consecutive number 1 debuts.

The album was announced while Shiho Ochi and her backing band were performing on a live stream of a recording session, broadcast via Ustream and Nico Nico Douga while celebrating the release of their recent video album Shout In the Rainbow!!. One of the new songs on the record will be "Heisei Homo Sapiens" (平成ホモサピエンス, Heisei Homo Sapiensu). The band's singles "Ai o Kurae", "Kagayaku Tsuki no Yō ni" and "The Bird Without Wings" were included on the album. The song "No Bandage", used on Superfly's Facebook radio show, was released to iTunes and other digital stores as a promotional single on July 18, 2012. The title track "Force" was also released to iTunes as a special album pre-order incentive. A re-cut version of the song will serve as the album's final single.
