Singing Competition

On 12/31 every year, NHK airs "Kohaku Uta Gassen" (Singing competition between red and white teams) It showcases singers of almost every generation who have been very popular among the Japanese. So it's quite interesting to watch those different generations of songs, performers, costumes, and so forth, within the same program. They do carry different cultural idioms and histories of the supposedly single nation called Japan.
