Flooding surrounding Japanese river has led to evacuations of around 100,000 people as the raging waters are wreaking havoc through the region.

The city of Joso, which is about 30 miles northeast of Tokyo, was among the worst hit by the deluge of rain and flooded rivers, authorities said.

Video footage shot from helicopters shows how some residents climbed to their roofs as they tried to get help by rescue workers.

In addition to the clear danger facing residents, Japanese authorities are particularly concerned about the flooding, given its proximity to one of the country's biggest nuclear power plants, Fukushima -- damaged by the 2011 earthquake and subsequent tsunami.

"The torrential downpour is threatening safety at the Fukushima nuclear plant, closed since the 2011 disaster, as it has overwhelmed drainage pumps at the site’s contaminated water treatment facility," a Japanese government official told ABC News.

More than 31,000 people who live in the 14-square-mile area of impacted Joso gathered in schools and community centers for shelter, according to the Associated Press.

Members of the state military were delivering food and water to about 780 others who were stranded but decided that they were not going to evacuate, the AP reported.

There have been no reports of fatalities yet, but the Fire and Disaster and Management Agency said that 22 people have been injured during the storms over the past two days, according to the AP.
