TOKYO : Powerful Typhoon Nangka lashed Japan on Friday, killing at least two people and triggering floods as authorities urged more than 230,000 residents to evacuate.

Local authorities urged at least 230,000 people in the storm's path to evacuate, according to Japan's public broadcaster NHK.

A 71-year-old who was trying to reinforce window panes was found dead on Thursday in Awaji island, Hyogo prefecture, a local official said, adding a few landslides had also been reported.

"Winds are getting weaker but rain remains quite heavy," the official said. "We are still asking our residents to stay on alert."

An 85-year-old who had apparently gone out to check on farmland was found dead Thursday night in Shiso, also in Hyogo prefecture, another official said. NHK said at least 39 people had been injured in the storm.
