C&K is a Japanese vocal duo consisting of CLIEVY and KEEN. Formed in 2010 and signed to Universal Music LLC, C&K blend pop, R&B, soul, and reggae-influenced elements into a harmony-driven sound built around strong vocal contrast and compact songwriting.
The duo built its reputation through live performances and a catalog of singles and albums that established C&K in the Japanese pop scene. Their songs are often recognized for catchy hooks, layered harmonies, and a balance of accessibility and vocal technique that works across upbeat tracks and more emotional material. As a long-running male vocal duo in Japan, C&K have developed an identity centered on consistency, vocal chemistry, and a versatile approach to modern Japanese pop.
