Fears of landslides and flooding put southern Japan on high alert Thursday as heavy rains continued to lash the region, prompting authorities to order more than 1 million people to evacuate.

Despite the orders, just 3,000 people were in shelters in the Kagoshima region on Thursday morning, an official tally showed.

The rains come a year after torrential downpours in western Japan that killed over 200 people in flooding and landslides. One woman has so far been killed in the rains that began at the weekend, ­after her house was buried in a landslide. ­Several injuries have been ­reported along with small landslides that have buried cars.

More than 1 million people in Kagoshima remained under evacuation order on Thursday morning, with additional orders being issued along with lower-level evacuation advisories.

Television footage showed cars swept away by floods and rivers breaking their banks in Kagoshima. 

At an evacuation center in the region, elderly residents sat on the floor eating, with their bedding and other belongings spread out around them.

The evacuation order is issued when a natural disaster is highly likely to occur and municipalities repeatedly urge residents to leave their homes, although the instruction is frequently ignored.

It is the most serious warning issued before a disaster actually occurs. The scale's highest level is activated once a disaster is declared and orders people to take measures to protect their lives. 

The Japan Meteorological Agency has warned that life-threatening landslides are possible.

Heavy rain was moving northwest Thursday and forecast to bring downpours to central and eastern Japan in coming days.

Kagoshima Governor Satoshi Mitazono said in a message Wednesday to residents that the situation was "extremely dangerous."

"A major disaster could happen anywhere, anytime," he said, adding that he had requested help from the military.
