KYONAN, Japan — Typhoon Hagibis swirled toward Japan early Saturday morning, as residents in the most vulnerable areas moved to evacuation centers and forecasters issued extreme weather warnings for multiple prefectures along the country’s eastern coast.

The Japan Meteorological Agency said early Saturday that the typhoon was about 200 miles southwest of Hachiojima, a tiny island off the central east coast. with winds of about 100 miles per hour at its center. The agency said the storm was expected to make landfall on Saturday evening.

At a news conference Friday morning, the agency warned that Hagibis could be as severe as the Kanogawa Typhoon, one of the deadliest on record, killing more than 1,200 people when it hit Shizuoka Prefecture and the Tokyo region in 1958.
