A powerful typhoon pummelled Japan's southern island of Okinawa Saturday, injuring at least five, as weather officials warned the storm would rip through the Japanese archipelago over the weekend.
Typhoon Trami, packing maximum gusts of 216 kilometres (134 miles) per hour near its centre, was forecast to hit the mainland early Sunday and could cause extreme weather across the country into Monday.
Television footage showed branches ripped from trees by strong winds blocking a main street in Naha, with massive waves splashing on breakwaters on a remote island in the region and torrential horizontal rain.
Some 600 people evacuated to shelters in Okinawa and electricity was cut to more than 121,000 homes, public broadcaster NHK said.
At least 386 flights were cancelled mainly in western Japan, according to public broadcaster NHK.
Five people suffered injuries in storm-related accidents in Okinawa, but no one was feared dead, local officials said.
