History.
2002–2003: Hello! Project Kids.
All of the group's members were initially selected during the audition for Hello! Project Kids in 2002 and undertook professional training in Hello! Project.
In 2002, Maasa Sudo and Risako Sugaya appeared in the Minimoni movie "" as members of the group 4Kids.
In 2003, some Hello! Project Kids' members were placed in bands led by Morning Musume members. Miyabi Natsuyaki was selected to be in Aa!, while Saki Shimizu and Momoko Tsugunaga were in the group ZYX. Both units were short-lived, and their activities stalled with the creation of Berryz Kobo.
2004: Formation and debut.
The formation of Berryz Kobo was announced at a Hello! Project club event on 14 January 2004. The band was composed of eight members of Hello! Project Kids, who were then known as the "starting line-up". Initially it was planned to rotate all 15 members of Hello! Project Kids through the group, which would have given Berryz Kobo's members more time for school. Later, however, the idea was dismissed, and the remaining seven Hello! Project Kids members formed the group Cute in 2005.
On 3 March 2004, the new band debuted with the single "Anata Nashi de wa Ikite Yukenai", which ranked 18th on the Oricon Weekly Singles Chart. Two more singles followed in April and May, and on 7 July the group released its first album, titled "1st Chō Berryz".

On 11 September 2005, it was announced that Maiha Ishimura would graduate from the group and Hello! Project to focus on her studies. Ishimura's graduation took place on 2 October 2005, on the last night of the Berryz Kobo autumn 2005 concert tour.

On 8–10 June, the group appeared at AnimeNEXT in Somerset, New Jersey, their second live performance in USA. On 20 June, the group released its second collaboration CD single with fellow Hello! Project Kids group Cute, named "Chō Happy Song" ("Super Happy Song.") The title tune is an overlay of two previously published songs, Berryz Kobo's "Because Happiness" and Cute's "Shiawase no Tochū" ("On the Road to Happiness") from their 2012 albums, which were composed and produced by Tsunku intentionally to form a new song when played simultaneously. The trick was originally scheduled to be announced at a summer Hello! Project concert, but was uncovered by fans in mid-April. The song became widely discussed on the Internet, and the set of three tracks, "Because Happiness", "Shiawase no Tochū", and "Chō Happy Song", was hastily released as a digital download single on 28 April.

2014: Tenth anniversary and indefinite suspension.
It was announced on 2 August 2014, at the summer Hello! Project concerts that Berryz Kobo would be going on an "indefinite suspension starting Spring 2015". The girls decided together that they would like to explore other opportunities. The decision to call this an "indefinite suspension" was made since the girls felt calling this move a "disbandment" would cause Berryz Kobo to disappear or fade away. The group continued its activities until the spring of 2015, when their final appearances and performances would be announced and take place. Tsunku added he would "like to see them chase new dreams" and asked for continued support throughout their remaining time as an active group.
On 24 February 2015, Shimizu and Tokunaga announced on their blogs they would remain with the company as advisors, where they would act as the "go-between" for the staff and members.

The following day Kumai stated on her blog that she would finish her university degree and would pursue a modeling career.
