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.

Axar.az reports citing Press TV that Typhoon Faxai powered into the Tokyo region in the early hours of Monday last week, packing record winds that brought down power lines, disrupted Rugby World Cup preparations and prompted the government to order tens of thousands of people to leave their homes.

The storm killed two people, with at least three elderly later confirmed dead due to heatstroke as temperatures soared to above 35 degrees Celsius (95 degrees Fahrenheit) in areas affected by a post-typhoon blackout.

Some 78,700 households were still without power in Chiba, southeast of the capital, Tokyo Electric Co. (TEPCO) spokesman Naoya Kondo told said. "A complete recovery is still unlikely until September 27 as we have difficulties in mountain areas," he added.
