Powerful Typhoon Chaba battered southern Japanese islands early Tuesday, bringing strong winds and heavy rainfall to the region.
More than 800 residents evacuated their homes and 3,670 households suffered power outages after the season's 18th typhoon pounded the Okinawa main island region overnight, the Okinawa Times newspaper reported.
As of 10 am (0100 GMT), the eye of the storm was over the East China Sea, travelling north at 20 kilometres per hour (kph), with maximum sustained winds of 198 kph and gusts of 270 kph, the Japan Meteorological Agency said.
The storm is projected to hit either the southern part of the Korean Peninsula or the northern part of Japan's Kyushu island on Wednesday morning.
The agency issued emergency weather warnings late Monday as the rapidly-intensifying typhoon approached the Okinawa main island region. They were lifted Tuesday morning.
Typhoon Lionrock hit north-eastern Japan in late August, leaving more than 20 people dead. It was the first typhoon to make landfall in the north-east since the agency started compiling comparable data in 1951.
