KYOTO — Japanese newspapers are eventually going to have to charge users to read general news stories online, media mogul Rupert Murdoch said Sunday at a conference here of scientists and engineers.

"They won't have a choice," said Murdoch, chairman and managing director of News Corp. and owner of The Wall Street Journal, The Times of London, and Fox News in the United States.

He was responding to a question about whether Japan's news media need to charge for their online news to make up for sagging advertising revenue and declining readership of their paper versions.
