The strongest storm to hit Japan this year has forced the evacuation of about 450,000 people on the islands of Kyushu and Shikoku, as well as Okinawa which was hit by Vongfong on Sunday, according to NHK.

Vongfong battered the southern Japanese island of Okinawa, 600 km south of Tokyo, as well as Kyushu and Shikoku islands, injuring 52 people, NHK said.

On Sunday, wind-speeds weakened significantly on Saturday's peak of 234 kmh hour, which had made Vongfong into a “super typhoon”.

Japan Airlines Co spokesman said 92 flights connecting Japan's western cities and the eastern cities of Osaka and Tokyo had been cancelled.
