NHK Kouhaku Uta Gassen (NHK紅白歌合戦, "NHK Red and White Song Battle"), more commonly known simply as Kouhaku, is an annual New Year's Eve television special held on December 31 every year, and produced by Japanese public broadcaster NHK. It is broadcast live simultaneously on NHK General TV, BS4K, BS8K and NHK radio (nationally) and internationally on NHK World Premium and some overseas (mainly cable) broadcasters who buy the program. The program divides the most popular music artists of the year into competing teams of red and white. The 'red' team or 'akagumi' (紅組) is composed of all female artists (or groups with female vocals), while the 'white' team or 'shirogumi' (白組) is all male (or groups with male vocals).
L'histoire tourne autour de "Aikatsu Planet", un monde virtuel où n'importe qui peut assumer le rôle d'un avatar et devenir une idole adorablement mignonne. Mao Otoha, un étudiant ordinaire de première année à l'académie privée Seirei High School, devient l'avatar idole n ° 1 Hana lorsque l'ancien alter ego de Hana, Meisa Hinata, a soudainement disparu. Cependant, le nouveau rôle de Mao en tant qu'avatar Hana est un secret pour tout le monde.
This program introduces Japanese traditional performing arts like dance, kabuki, bunraku.
