Chaba, meaning hibiscus in Thai, is moving slowly northwest and generating maximum windspeeds of around 160 kilometers (100 miles) per hour, the Japan Meteorological Agency said.

Due to the typhoon, some 5,800 households had no electricity in the island, 1,300 kilometers (800 miles) south of Tokyo, police in Amami-Oshima said.

The typhoon is likely to hit parts of Kyushu island in southwestern Japan by early Monday and dump up to 800 millimeters (32 inches) of rain in the region, the Meteorological Agency said.

Waves in Kyushu could reach as high as eight meters, the agency added.

At least 27 flights from Tokyo to Kyushu were cancelled Sunday due to the typhoon, an airport official said.
