Heavy rain drenched wide areas of Japan on Monday, with downpours causing a mudslide and a train derailment in Shimane Prefecture and prompting Ishikawa Prefecture to order more than 10,000 people in Kaga to evacuate.

In Unnan, Shimane Prefecture, heavy rain triggered a mudslide that crushed a home, burying two people. They were rescued but one of them, a 38-year-old woman, remains unconscious, while her 77-year-old father sustained slight leg injuries, Shimane Prefectural Police said.

In Matsue, also in Shimane, a mudslide near Nagae Station on the Kita-Matsue Line caused a two-car train to derail after it ran into mud on the tracks at around 10 a.m., according to Ichibata Electric Railway Co.

The mud caused the first car of the train carrying some 30 passengers to tilt 45 degrees. But there were no injuries, the railway said.

In Kaga, the front dumped 200 mm of rain from 6 a.m. Sunday to 7 a.m. Monday, threatening to cause the city's rivers to flood the surrounding areas.

The Ishikawa Prefectural Government Monday morning ordered 10,100 people at 4,200 households to evacuate the areas close to these rivers.

The Meteorological Agency said the seasonal rain front is engulfing large areas of the country, stretching from the eastern area surrounding Tokyo to the Hokuriku region to the Sanin coast in western Japan facing the Sea of Japan.

The agency said the front is expected to bring heavy rain to a wide area from Monday to Tuesday.
