Typhoon Faxai moved northwest over the Pacific toward eastern Japan on Saturday, threatening to make landfall near Tokyo as early as Sunday night, the Meteorological Agency said.

The season's 15th named storm, packing winds of up to 180 kph (about 112 mph), is expected to reach coastal areas of the Kanto region between late Sunday and early Monday, it said.

As of 9 p.m. Saturday, Faxai was traveling about 200 km (125 miles) north of Chichijima Island in the Pacific at a speed of 30 kph (18 mph), the agency said.

In the 24 hours through midday Sunday, the typhoon is forecast to bring between 200 and 400 mm of rain to coastal regions of central and eastern Japan.
