“It wasn’t just the rain, there was thunder and lightning, too. I couldn’t see anything ahead of me,” one woman at an evacuation center told NHK.
A schoolboy sitting with his family told NHK, “I haven’t heard from some of my friends, and I’m really worried.”
There were no immediate reports of major transportation problems, but television footage showed a railway line left broken and twisted by floodwaters.
The same area was pounded by heavy rain earlier this week from Tropical Storm Nanmadol, which has since passed out to sea.
The rain in Japan comes on the heels of a storm system that caused severe flooding across southern China and that killed 56 people and cost almost $4 billion in damage.
