This is a very surrealistic appearance by J-Pop idols Berryz Koubou on a Japanese kids show:
So who is Berryz Koubou? Berryz工房 (Berryz Koubou or Berryz Kobo) is a Hello! Project group featuring seven Hello! Project Kids. The name Berryz Koubou, which means "Berryz Workshop", reflects the initial idea that the group's line-up would change from time to time, with each of the Hello! Project Kids eventually participating in the group. However, this idea was apparently dropped and in 2005, the other seven Hello! Project Kids ended up forming their own group, °C-ute.
Berryz Koubou debuted at a concert on March 3, 2004, and they often perform as backup dancers for W's promotional videos. Even though there are exceptions (such as album songs) the lead singers in Berryz Koubou are always Natsuyaki Miyabi, Sugaya Risako,Tsugunaga Momoko and sometimes Kumai Yurina.
