Heavy rain is once again expected to pound Japan, with areas still recovering from extensive flooding brought by Typhoon Hagibis earlier this month likely to be hit again, the weather agency here said Thursday.

Rescuers in Japan worked into a third day on Tuesday in an increasingly desperate search for survivors of a powerful typhoon that killed nearly 70 people and caused widespread destruction.

Almost 80,000 homes are still without power a week after a powerful typhoon battered eastern Japan, authorities said Monday, with sustained heavy rain prompting evacuation orders and hampering recovery efforts.

Japanese utility Tokyo Electric Power said on Wednesday it has not been able to restore electricity to about 400,000 homes after outages caused by Typhoon Faxai, while media reported at least two people had died because they had no power.

One of the strongest typhoons to hit the Japanese capital in recent years.
