The death toll from torrential rains-triggered flooding and mudslides in eastern and northeastern Japan climbed to 10 on Saturday, with three others still missing, reported NHK, Japan's national broadcaster.

More than 200 millimeters of rain fell over 12 hours in some areas of Chiba and adjoining Ibaraki prefecture, according to the reports. That's more than the average for the whole of October.

Several rivers in Chiba flooded, inundating roads and residential areas. Rescuers say the floodwaters are making it difficult to access some areas.

Some roads were closed and about 4,700 households were still without water in the city of Kamogawa, Chiba.

Prime Minister Shinzo Abe held a disaster task force meeting on Saturday, calling for "the utmost effort in rescue and relief operations."

Local authorities have issued evacuation orders and advisories along much of the northern corridor already hit by two typhoons since last month.
