Japan Censors Information

"The Japanese government says that the damage caused by earthquakes and by the nuclear accident are being magnified by irresponsible rumors, and the government must take action for the sake of the public good. The project team has begun to send letters of request to such organizations as telephone companies, internet providers, cable television stations, and others, demanding that they take adequate measures based on the guidelines in response to illegal information. The measures include erasing any information from internet sites that the authorities deem harmful to public order and morality."
