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). Factory follows a similar naming pattern as earlier 8-member group Berryz Koubou, koubou (工房) meaning workshop.
A Capella and Voice PercussionEdit
Kobushi Factory, in addition to being an idol group, have performed as an a capella group. In the midst of Kobushi Factory's line-up changes in 2017, member Inoue Rei began learning voice percussion, and her first lesson was included on the September 27, 2017 episode of Hello! Project Station in the "Documentary of Hello! Project (DOHP)" corner. From there, the other five members of Kobushi Factory had a capella lessons that were also featured on the web show, and the whole group began learning to cover "Chotto Guchoku ni! Chototsumoushin" a capella in preparation for the Kobushi Factory Live Tour 2017 Aki ~Songs For You~.
After Taguchi Natsumi's resignation from the group, they continued learning voice percussion and a capella, and performing a capella versions of their songs at concerts and events. Kobushi Factory released a video of the a capella version of "Chotto Guchoku ni! Chototsumoushin" for OMAKE CHANNEL on September 10, 2018. Additional a capella covers were later released on the channel, and studio versions were recorded for their second album Kobushi Dai Ni Maku.
