Another typhoon is moving into Japan and may strike the biggest populated region as early as this afternoon.

Many people in central Japan have been advised to evacuate as a powerful typhoon approaches. The storm system has already triggered floods that have left two people missing.

Public broadcaster NHK says some 1.3 million people have been ordered or advised to evacuate, including 80,000 people in Nagoya.

The Meteorological Agency says the typhoon was located near the southern island of Tanegashima last night and it could reach the Tokyo area by later today.

Gifu prefectural police say a 9-year-old boy and an 84-year-old man are missing after apparently falling into swollen rivers due to heavy rains from the approaching storm.

A typhoon that slammed Japan earlier this month left some 90 people dead or missing.
