More than 1,000 firefighters in northern Japan battled to contain two wildfires for a fifth straight day on Sunday, as the blazes pushed closer to residential areas and forced more than 3,000 residents to evacuate.

The first fire broke out on Wednesday in a ?mountainous ?area and then a second fire nearby threatened residential districts in the town of Otsuchi ?in Iwate Prefecture.

Hilly terrain, dry weather and winds are hampering containment efforts, a fire department official told reporters.
