A tornado touched down Monday afternoon in Koshigaya, Saitama Prefecture, injuring 63 people and wrecking more than 100 buildings before going on a 14-km rampage into neighboring Chiba, local police said.

The wind funnel swept through houses and fields around 2 p.m., knocking down utility poles, peeling off roofs and sending all manner of objects into the air.

One man's skull was apparently fractured by an object sent flying by the tornado, the police said.
