A tornado has torn through an area north-east of the Japanese capital Tokyo, injuring at least 30 people and destroying dozens of homes.
The fire department said the tornado struck today in the city of Tsukuba, 40 miles from Tokyo.
Firefighters and helicopter medical teams rushed to the area, and 30 to 50 homes have been destroyed.
TV footage showed rows of houses that had lost roofs, and apartment complexes with smashed balconies and shattered windows. It also showed footage of a swirling grey cloud said to have been taken by a passer-by.
Tornadoes are relatively rare in the Tokyo area. Tornado warnings were issued in north-eastern Japan, including Tokyo.
