GRe4N BOYZ in Ōita

GRe4N BOYZ is a Japanese pop vocal group formed in Koriyama in 2002 by HIDE, navi, 92 and SOH, all of whom became dentists and have kept their faces private. Known as GReeeeN until adopting its present name in 2024, the quartet is closely associated with the songs “Kiseki,” “Ai Uta” and “Haruka.” The group began nationwide concert touring in 2013 while preserving the members’ anonymity through projected characters and video imagery. That format also shaped its tenth-anniversary concert in 2017 at Saitama Super Arena.
