Typhoon Haishen, the second powerful typhoon to slam Japan in a week unleashed fierce winds and rain on southern islands on Sunday, blowing off rooftops and leaving homes without power as it edged northward into an area vulnerable to flooding and mudslides.
Weather officials warned that rainfall from what could be a record storm would be as fierce as a bucket of water poured over your head.
Warnings have been issued, days in advance, for people to be ready to take shelter and to stock up on food and water.
Officials said several rivers on the main south western island of Kyushu were at risk of overflowing.
The Japan meteorological agency said Typhoon Haishen was packing sustained winds of up to 180 kph as it battered Okinawa and the southern
Kyushu island of Amami Oshima early Sunday.
