AlHijjah 19, 1435, October 13, 2014, SPA -- The strongest storm to hit Japan this year battered the southern islands of Kyushu and Shikoku early on Monday, brought heavy rain to Tokyo and caused extensive travel disruption, Reuters reported. Typhoon Vongfong has forced the cancellation of more than 500 domestic flights, the public broadcaster NHK said. At least one overseas flight was cancelled, according to an airline. Many trains in western cities were also suspended, NHK said. More than 820,000 people have been urged to leave their homes, it said. About 4,900 households in Tokyo suburbs were without power, media said. Rain in Tokyo was expected to intensify overnight. Vongfong battered the southern Japanese island of Okinawa, 600 km (1,000 miles) south of Tokyo, as well as Kyushu and Shikoku islands, injuring 59 people, NHK said.
