A slow-moving but weakening Typhoon Noru, at one point the strongest storm in the world this year, approached Japan's main islands on Sunday, leaving two people dead and prompting evacuation advisories to be issued for hundreds of thousands of people.

The typhoon may make landfall on Shikoku early Monday after moving north off the east coast of Kyushu, the Meteorological Agency said.

As of 8 p.m. Sunday, Noru was roughly 130 km (80 miles) south-southwest of Kochi Prefecture and moving northeast at a speed of 20 kph. It had an atmospheric pressure of 975 hectopascals at its center and packing winds of up to 162 kph (100 mph), according to the agency.
