According to the Sports Nippon newspaper, Korean groups BIG BANG and KARA will be making their first appearances in the NHK Kohaku Uta Gassen. The last Korean artists to perform at Kohaku were Lee Jung Hyun and RYU in 2004, but BIG BANG and KARA will be the first groups ever to appear.
BIG BANG, who made their debut in Japan last year, will be participating as an ordinary member of the White Team, rather than as part of a special project. They are planning to arrive in Japan on December 26 and stay until the new year. This means that they will be absent for NHK's annual press conference introducing the first-time Kohaku participants, but they have already recorded a video message for the event.
KARA debuted in Japan just this year. They will be part of the Red Team, but details about their participation are not yet known.
