KinKi Kids is a Japanese popular group established by Johnny & Associates. The group members are Tsuyoshi Domoto (堂本剛, Dōmoto Tsuyoshi) and Koichi Domoto (堂本光一, Dōmoto Kōichi).
They made their debut in 1997 with their single Glass no Shounen (Glass Boy), which made them a number one on the hit chart ORICON for many weeks. They are also listed in the Guinness Book of Records, where they are credited with having most number of consecutive singles that debuted at #1 on their charts. These CDs include Eien no Bloods (Forever Blood) and Hey Minna, Genki Kai? (Hey! How's everybody?). As of writing, all 24 of their singles have debuted at #1.
Widely known in Japan, the KinKi Kids are very popular among girls of all ages, and their subscription concerts even draw boys. Not only do they sing, but they are also talented actors, having appeared in popular dramas and sitcoms. For example, Tsuyoshi played a part in Kindaichi Shounen no Jikenbo (Young Kindaichi's case files), and Koichi was in Remote. They have their own variety show called Domoto Kyoudai (The Domoto brothers). However despite their shared surnames they are in fact completely unrelated and hail from two different prefectures in the Kinki region (according to the Japanese version of this page.)
KinKi Kids are signed and promoted by Johnny and Associates. Other well-known Johnny and Associates groups include SMAP, TOKIO, V6, NewS and Arashi.
