berryz Kobo.

berryz Kobo is a Japanese Lolita group, established on January 14, 2004.

Berryz Kobo belongs to HELLO! PROJECT Fixed group In 2002, Tsunku, the director of HP, launched the HELLO! KIDS project. From 27,958 people recruited across Japan, 15 little girls aged from 8 to 12 years old were selected and called Hello! Project kids. At the time of its establishment The average age of the first members is only 10.75 years old, and they are all in the compulsory education stage. Therefore, they have adopted a policy of non-fixed members, but the members have not been changed so far; with the remaining Hello! Project kids members on June 11, 2005 It was officially announced that they would form another group ℃-ute, and the possibility of Berryz Kobo members being changed was greatly reduced. The eight starting members are Saki Shimizu (captain), Momoko Tsunaga, Chinami Tokunaga, Moma Sudo, Masaru Natsuyaki, Maiami Ishimura (left the team on October 2, 2005), Yurina Kumai and Risako Sugatani. Has high support within certain groups. Five singles and one album were released within one year of its establishment, with mediocre sales. Oricon's highest weekly single sales ranking was No. 7 (スッペシャル ジェネレーション, April 4-April 10, 2005?). Later, he formed a new group with the members of Good Morning, respectively forming 4kids (Hagiwara Mai, Suzuki Airi, Sudo Moma, Sugatani Risako), ZYX (Ari Yaguchi , Umeda Umeda, Yajima Maimi, Murakami Ai Shimizu Saki) Momoko Tsusunaga) あぁ! (There are Tanaka Rina Suzuki Airi and Natsuki Masaru) But these are temporary combinations.

On January 14, 2004, 8 members were finally selected from 15kids as Berryz Kobo members. At the beginning of its establishment, with an average age of 10.8 years old, it set a record for the youngest music group in Japan. On March 3, 2004, the first single "あなたなしでは生きてゆけない" ??was released, officially debuting. When Berryz Kobo debuted, it was at the low point of HP. The graduation of the old members of Good Morning led to a decline in popularity. At a young age, the B-workers and HP seniors took up the responsibility of revitalizing the HP family. They lived up to expectations and released 10 singles and 2 albums in two years, maintaining an average rate of one every two months. According to incomplete statistics, he participated in 57 publicity activities such as handshake meetings, face-to-face meetings, and press conferences. Organized 46 concerts (including solo and non-solo).

Origin of the name

Evolved from berry: berry->berries->berryz->berryz workshop. Berry is the general name for strawberry fruits, which are usually small in size and rich in moisture. This name is based on the hope that the music expressed by berryz Kobo can have a similar feeling.
