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 '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).

National treasures, important cultural properties, and other supreme treasures are displayed in glass cases in museums and art galleries. You want to hold them in your hands and take a closer look at their backsides and details. In response to this desire, "Solve the Mystery! Secret Treasures" uses a high-resolution camera and the latest digital technology to create an ultra-high definition 3DCG image that is a perfect match for the real thing.

The program also challenges viewers to solve art history and historical riddles using the "detailed depictions" and "traces" of the creators on the treasures as clues!
