Japan will punish people who create or wilfully spread computer viruses with fines and prison terms of up to three years under a new law enacted by parliament.
Under the law, police can seize email communication logs of suspects from Internet service providers, among other information.
Under Japan's new law, people who create or distribute a computer virus with no justifiable reason face prison terms up to three years or fines up to 500,000 yen (6,200 dollars). Those who deliberately store a computer virus face up to two years in prison or fines up to 300,000 yen.
The text of the law says that "in view of the realities of cyber crime associated with the advancement of information processing ... it is necessary to develop the necessary regulations".
