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).

Its story is set in Aikatsu Planet, a world where everyone can become cute idols using an avatar. While spending school life, the main characters are aiming to become top idols. Everyday parts such as the main character's school life will be filmed in live-action, and the Aikatsu Planet! world will be drawn in anime and 3DCG (like the previous series). The live-action part's cast members will form a unit "STARRY PLANET*" and perform as idols at events and on YouTube. A new Data Carddass game linked to the TV series, "Data Carddass Aikatsu Planet!" is also scheduled to begin its service this winter.

This program introduces Japanese traditional performing arts like dance, kabuki, bunraku.
