Rainbow 7 (レインボー7) is the seventh album by the J-pop idol group Morning Musume. It is the first album to feature 7th generation member Koharu Kusumi and first album after graduation of Kaori Iida and Rika Ishikawa and departure of Mari Yaguchi. It was released on February 15, 2006.
Overview
The album features the last single A-sides to feature founding member Kaori Iida and long-time members Rika Ishikawa and Mari Yaguchi, all of whom departed the band (Iida for a solo career, Yaguchi because of a scandal though she now works as a general entertainer, Ishikawa to focus on her new group V-u-den) in the months after their previous studio album, Ai no Dai 6 Kan, was released. Although their vocals are heard on these tracks, they are not credited anywhere in the liner notes. One of the singles represented, "Chokkan 2 (Nogashita Sakana wa Ōkiizo!)", appears in remixed form.
Three of the songs on the album are performed by smaller clusters of several group members, and are credited in the liner notes to the featured members involved, rather than to the entire band.
Two different versions of the album were released, different from the usual "first press" versions. The limited edition version contained a 32-page photobook and had special packaging. When the two versions were announced it was said that each version (limited and normal) would have a different bonus track but, due to a problem on the manufacturer's end, the idea was abandoned.
