According to information agencies, officials of NTT DoCoMo, Japan's largest telecommunications operator, have announced a possible personal data leak about 24,632 cellular communications subscribers of said company. Amongst the “leaked” information are names, addresses, home and cellular phone numbers of the NTT DoCoMo clients.
Most of the subscribers from the list live on the north-east of Niigata prefecture – an area, which suffered a series of strong earthquakes last October. Because of that, the operators introduced lowered cell phone rates in that area.
