Japan's NHK television is setting out to do something very nice for tourism in Nepal. The capital is to be featured in a six-episode series on Asia's "mysterious cities" alongside Beijing, Banaras, Jogjakarta, Isfahan and Kyoto. The crew is in town shooting footage on High Definition Digital Television (HD-TV)-the latest technology-and will show the growth of the city and its culture from the Kirati era up to the present, using computer generated graphics to showcase what it is not possible to film.
