AT LEAST four people are dead and 100 injured after Typhoon Hagibis slammed into Japan with the heaviest rain and winds in 60 years.
More than seven million people were evacuated and 17 people are still missing after the 11mph mature tropical cyclone made landfall on Saturday.
A man in his forties was among the dead when his car overturned in a tornado east of Tokyo, while others were injured when gales tore the roofs off a number of homes.
News broadcaster NHK warned the numbers of casualties may grow, as rescue teams attempt to reach those stranded in flooded areas. More than 370,0000 homes lost power.
Shortly before the typhoon made landfall a 5.7-magnitude earthquake was centred in the ocean off the coast of Chiba, near Tokyo.

The Japan Meteorological Agency issued the highest alert level for 12 regions, including Tokyo, warning of amounts of rain that occur only once in decades.
Agency official Yasushi Kajihara said: "Be ready for rainfall of the kind that you have never experienced.
"Damage from floods and landslides is likely taking place already.
"It is critical that people take action urgently to protect their lives and the lives of loved ones."
Kajihara said people who live near rivers must take shelter on the second floor or higher of any sturdy building if an officially designated evacuation centre wasn't easily accessible.
The rough weather has caused 1,600 flights to be grounded, while shops and factories have also been closed.
Weather models project the monster storm will continue on a north-westerly path towards as it made landfall this morning.
Nobuyuki Tsuchiya, director of the Japan Riverfront Research Center, said Tokyo, where 1.5million people live below sea level, said residents are at risk of storm surges.
He said: "We are heading towards high tide. If the typhoon hits Tokyo when the tide is high, that could cause storm surges and that would be the scariest scenario.
"People in Tokyo have been in a false sense of security."
Hagibis, which means "speed" in Filipino, was advancing North with maximum sustained winds of 111mph, according to the meteorological agency.
The deadliest Typhoon to hit Japan was Typhoon Ida, known as the "Kanogawa Typhoon" in 1958 where it killed more than 1,000 people.
Rugby World Cup matches have also been changed for October 12 and 13.
England vs France in Yokohama is among those to be called off, with Sunday's matches still under consideration.
But Scotland are hoping they are still able to play Japan in Yokohama on Sunday, with a quarter-final spot up for grabs.

What is the difference between a cyclone, typhoon and hurricane?
The difference between them is their location.
Hurricanes are tropical storms that form over the North Atlantic Ocean and North East Pacific.
Cyclones are formed over the South Pacific and Indian Ocean and typhoons form over the North West Pacific Ocean.
Hurricanes and typhoons are tropical cyclones - which is a generic term to indicate rotating systems of clouds and thunderstorms over tropical or subtropical waters.
