Kōhaku Uta Gassen

Kōhaku Uta Gassen, more commonly known as simply Kōhaku, is an annual music show on New Year's Eve produced by Japanese public broadcaster NHK and broadcast on television and radio, nationally and internationally by NHK's networks and some overseas broadcasters which bought the program. The show ends shortly before midnight.

Literally "Red and White Song Battle," the program divides the most popular music artists of the year into competing teams of red and white. The "red" team or akagumi is composed of all female artists, while the "white" team or shirogumi is all male. The honor of performing on Kōhaku is strictly by invitation, so only the most successful singing acts in the Japanese entertainment industry can perform. In addition to the actual music performances, the costumes, hair-styles, makeup, dancing, and lighting are important. Even today, a performance on Kōhaku is said to be a big highlight in a singer's career because of the show's large reach.
