A very strong typhoon is moving north over the Pacific near Japan's Ogasawara Islands. Weather officials warn that Typhoon Lan could come close to eastern and western Japan around Tuesday.

The Meteorological Agency said that as of 6 a.m. Saturday, the typhoon was slowly moving northwest over waters 150 kilometers north of Chichijima Island.

It had a central atmospheric pressure of 940 hectopascals and winds of up to 162 kilometers per hour near its center with maximum gusts of 234 kilometers per hour. Winds of more than 90 kilometers per hour were blowing within a 110-kilometer radius from the center.

Typhoon Lan is expected to continue heading northwest over the ocean south of Japan. Weather officials say heavy rain could fall in eastern and western Japan beginning Monday.

In the 24 hours through Tuesday morning, up to 300 millimeters of rain is expected in the Tokai region, 200 in Kinki, 150 in Shikoku, 100 in Kanto-Koshin and the Izu Islands.

The typhoon is still far away from Japan's main island of Honshu. But waves of 3 to 5 meters high are forecast on Saturday and 6 meters on Sunday along the Pacific coast areas from the Kanto through Kinki regions.

Weather officials are calling on people to pay particular attention to high waves and to stay away from them.
