As people in Japan continue to recover from Typhoon Hagibis, some cities are preparing for more heavy rain. Rescuers are still searching for 8 people, with the death toll now at 79.
Meanwhile, cities in some affected areas are bracing for more wet weather.
In Nagano, a dike has been erected where the riverbanks were washed away.
Farther north in Miyagi prefecture, sandbagging has begun to reinforce a damaged levee. Pump trucks have also been deployed to drain floodwaters.
Some cities are already issuing evacuation advisories to areas at risk of flooding from rivers.
Officials are urging people in disaster-hit areas to stay on the alert, saying even light rains could trigger further flooding and landslides.
More than 4,000 people are still staying in evacuation centers across the country.
Some shelters are taking steps to keep evacuees warm as the seasonal temperatures drop.
Health officials are also warning people in shelters to be wary of flu outbreaks.
The government is planning to designate Typhoon Hagibis as a severe natural disaster, as estimated restoration costs surpassed benchmark levels.
The government's designation means that larger subsidies will also be available to cover reconstruction of damaged roads, river, and agricultural land.
