Debuting in 2005 as a member of AAA, SKY-HI simultaneously launched his solo career as a rapper. In 2020, driven by the slogan “To never extinguish talent,” he established the management and label company, BMSG, Inc., and has since launched chart-topping groups like BE:FIRST, MAZZEL, and HANA. BMSG also manages various solo artists. SKY-HI has recently started “BOYS GROUP AUDITION PROJECT 2025 ‘THE LAST PIECE’” to form the third boy group in 2025. Under BMSG’s “TYOISM (read as ‘Tokyo-ism’)” philosophy, SKY-HI and BMSG continue to pursue delivering new culture from Tokyo to the world.
