The water supply to tens of thousands of households in two prefectures near Tokyo was cut off Saturday after local checks found it was contaminated with a cancer-causing chemical.
The city of Noda, Chiba Prefecture, some 30 kilometers from central Tokyo, said it had stopped supplies to a major part of the city. Most of the neighboring city of Kashiwa also has no tap water supply.
Water supplies have been cut to a total of 210,000 households in Chiba, where the two cities are located, according to Jiji Press news agency.
