The Japanese government has ordered the evacuation of 100,000 affected by floods, caused by Typhoon Etau.

Military helicopters have been helping to rescue trapped residents in Japan - following days of torrential rain and rising floodwater.

A river has burst its banks - sending a tsunami-like wall of water into the city of Joso - north east of Tokyo.

Elsewhere in the region, one woman is missing following a landslide.
