TOKYO - Power outages and scorching heat are compounding the struggles of residents after a powerful earthquake rocked southwestern Japan, forcing some to spend the night without air-conditioning and others to seek shelter in their own cars.

A day after around 10,000 people were evacuated following a magnitude 7.1 earthquake in Kumamoto Prefecture and nearby areas, thousands remained at over 400 shelters in the prefecture on Wednesday. Some shelters were not opened due to power and water outages.
