TOKYO -- Strong Typhoon Faxai is threatening to make landfall in eastern Japan sometime between Sept. 8 and 9, the Japan Meteorological Agency (JMA) said.

As of 6 p.m. on Sept. 7, the typhoon, this season's 15th, was located about 140 kilometers north-northeast of Chichijima, part of the Ogasawara Islands, and moving northwest at about 30 kilometers per hour, according to the JMA.

The atmospheric pressure at its center was 960 hectopascals and the typhoon was packing winds up to 40 meters per second (144 kilometers per hour). The maximum instantaneous wind speed was 60m/s (216 kph.)

Stormy winds are expected on the Ogasawara Islands, about 1,000 kilometers south-southeast of central Tokyo, from the afternoon to the evening of Sept. 7 and the sea around the islands is feared to be rough.

The typhoon will approach eastern Japan while maintaining its strength and could make landfall in the region sometime between Sept. 8 and 9. The JMA is warning of high waves, landslides and swollen rivers.

Damp air is expected to blow into areas in eastern Japan along the Pacific coast from the south between Sept. 8 and 9 as the typhoon approaches the region, destabilizing atmospheric conditions and bringing thunderstorms to some areas.

The amount of rain over a 24-hour period up to 6 a.m. on Sept. 8 is estimated at 100 millimeters in the Tokai region in central Japan. Rain over a 24-hour period until 6 a.m. on Sept. 9 is expected to be 300-400 millimeters in the Tokai region, 200-300 millimeters in the Kanto-Koshin region in eastern and central Japan, 200-300 millimeters on the Izu Islands south of Tokyo and 100-150 millimeters in the Tohoku region in northeastern Japan.
