Lady Gaga is to appear on a New Year\'s music show in Japan. Gaga will appear via videolink on a popular Japanese music competition on New Year\'s Eve, public broadcaster NHK said. The eccentric star\'s appearance on Kohaku Uta Gassen, an annual singing competition between male and female entertainers, will include her singing and delivering encouraging messages over Japan\'s devastating March 11 earthquake and tsunami, the broadcaster said on Saturday. The songstress visited Japan twice after the disaster and called on tourists from around the world to follow suit, and attended events to support reconstruction of disaster-hit areas. A song and message from the singer will be recorded shortly before the show, NHK said.
