Golden Goose Entertainment's huge boyband, 'A-Peace' (formerly known as Double B/21), is gearing up for their official Japanese debut! Japan has been keeping tabs on the debut, with mentions from Sankei Sports, TBS's "Kuraberu Kurabera," and special coverage from Fuji TV.  The members were cast and produced by Kim Kyung Wook, who's known for discovering and working with idols like H.O.T, Shinhwa, and TVXQ.  Comprised of a total of 21 members (each standing at a height of 185 cm), these flower boys are scheduled to perform at Japan's "K-Theater" every day. The band will be promoting as units with three different teams comprised of seven members each. On April 1st, A-Peace will be opening their official Japanese homepage in preparation for their debut.  The boys will be returning to promote in Korea after their Japanese debut.
