The concept of Koumi Jima Shuu 7 was born out of a collaboration between Japanese entertainment company, Sony Music Entertainment Japan, and the Nagano Prefectural Government. The goal was to create a group that would promote the region's tourism and cultural heritage, while also providing a platform for young artists to showcase their talents.
