Group Name OriginEdit

The word kobushi has multiple meanings. In this case it is supposed to represent both the coming of spring and grace of the kobushi magnolia (辛夷), as well as the strength of a fist (拳).[3] Factory follows a similar naming pattern as earlier 8-member group Berryz Koubou, koubou (工房) meaning workshop.[3]
