Berryz工房

Berryz Kobo (Berryz工房, Berryz Kōbō, literally "Berryz Workshop") was a Japanese idol girl group. The pop group was a part of Hello! Project, produced by Tsunku who also wrote their songs. Of all the musical acts in Hello! Project, Berryz held the title for the most consistent line-up, having kept all of its original members (with no new members added) since their one and only graduation (Maiha Ishimura) in 2005. The group was formed in 2004 and debuted with its first single in March of the same year. In 2007, Berryz Kobo became the youngest act ever to give a solo concert at Saitama Super Arena. In 2008, the group received the Best Asian Newcomer Award at the Asia Song Festival and a Cable Music Award at the 41st Japan Cable Awards ceremony. As of December 2014, the group had released 36 singles, 9 studio albums, 1 EP and 1 compilation album. Berryz Kobo's combined CD and DVD sales exceeded 1 million copies in Japan alone.
