Ai no Dai 6 Kan
Overview. "Ai no Dai 6 Kan" contains three hit singles, all released prior to the album between April and December 2004: "", "Joshi Kashimashi Monogatari", and "Namida ga Tomaranai Hōkago". Ai Kago and Nozomi Tsuji (who graduated from the group in August 2004 to continue with their duo W (Double You) full-time) perform along with the other 12 members of the group at the time on the first two aforementioned tracks, recorded and released as singles when they were a part of the group, and on "Ship To The Future", a song from Morning Musume 's Spring 2004 Musical "Help!! Atchii Chikyu o Samasunda". Another album track, "Help!!", is also from "Help!! Atchii Chikyu o Samasunda"; a slower version of the latter was recorded by band members Rika Ishikawa and Sayumi Michishige under the name Ecomoni and released on the compilation "Petit Best 5". The album was released at a pivotal and transitional time for the group, as upon its release in December 2004, it was already known that first generation member and group leader Kaori Iida and fourth generation member, Rika Ishikawa, would be leaving the group within three months of each other — Iida  to embark on a solo career and Ishikawa to concentrate on her new group V-u-den. "Ai no Dai 6 Kan" is also Mari Yaguchi's last album with the group, although she continues to work as a general entertainer under the Hello! Project banner that houses Morning Musume and its many offshoots. A new version of the album track "Chokkan: Toki to Shite Koi wa", entitled "" and featuring some different lyrics as well as new vocals by the post-Mari Yaguchi lineup, is the title track of Morning Musume's 28th single release. A live recording of the  original version of "Chokkan..." was released on December 21, 2005 on the Hello! Project compilation "Petit Best 6". The first pressing of album came in special packaging with a B3-sized special poster and Hello! Project Photo Card No. 0084. Track listing. All songs written by Tsunku
