At nine in Tokyo, several thousands of passengers were stranded due to a halt in operations of most train operators.

The Meteorological Agency announced several evacuation notices have been lifted except to Aichi and Mie Prefectures, where more than 60,000 citizens are still staying in evacuation centers.

In Odawara and Kanagawa Prefectures, more than 239,000 residents have been issued with evacuation order due to severe floods and fears of mudslides.
