Typhoon Nanmadol struck the coastline of southern Japan on Sunday, causing widespread power outages and a massive evacuation.
The Japan Meteorological Society said the typhoon could unleash up to 20 inches of rain by Monday with winds of more than 100 miles per hour as the storm reached the shore of Kagoshima City.
More than 12,000 people have already taken shelter at evacuation shelters, according to the Associated Press. About eight million people in southern Japan have been warned to evacuate, with calls across the regions for residents to stay inside buildings on the second floor or higher where possible.
The AP also noted that 216,450 homes were reported without electricity due to Typhoon Nanmadol. Trains on nearby Kyushu Island have also stopped operating as a safety precaution.
