亀梨和也
is a Japanese boy band formed under Johnny &amp; Associates (Johnny's) in 2001.

Their debut on March 22, 2006 was marked by a tripartite release of a CD single, album and music DVD on their exclusive record label J-One Records. Since then, all of their single, album and music DVD releases have debuted at number one on the "Oricon" music and DVD charts.
