A powerful typhoon slammed into Japan's main island on Thursday, killing at least one person as violent winds damaged homes, uprooted trees and prompted fears of landslides.

Typhoon Melor, packing gusts of up to 198 kilometres an hour, was cutting a swathe across densely populated central Japan — the first tropical storm to make landfall since 2007, the weather agency said.

It brought heavy rain and strong winds that ripped roofs off houses, damaged walls and toppled trees, blocking roads and railways in central Japan.

The typhoon weakened slightly as it churned across the main island of Honshu, but "is still very dangerous," said Takeo Tanaka, a weather forecaster from the Meteorological Agency.

"Winds are violent and rain is torrential. You should also be on guard against mudslides," he said.

The agency warned that extensive areas in Japan, including Tokyo and the western industrial hub of Osaka, were at high risk of landslides as the typhoon moved along the archipelago.

Television footage showed trucks blown over and cars abandoned in the middle of flooded roads.

A 54-year-old newspaper deliveryman died in western Wakayama prefecture after his motorbike hit a fallen tree, according to local police.

At least 22 people were injured by strong wind or heavy rain across the nation and thousands of people evacuated to shelters, public broadcaster NHK reported.

Airlines cancelled some 330 flights, mostly on domestic routes, while railway services — including bullet trains — were temporarily suspended.

Toyota Motor said it would suspend production at all 12 of its domestic plants Thursday.

More than 40 000 households were without electricity in western Mie and central Gifu prefectures early Thursday, while a blackout also hit 3500 households in Tokyo and 6820 in neighbouring Kanagawa, power companies said.

Strong winds in Tokyo caused trains to stop on the Yamanote train line, which loops around the capital and is used by millions of commuters every day.

Japan has built extensive defences against floods and landslides, including storm surge barriers in coastal areas.

But typhoons can still be deadly. Western Japan was battered in October 2004 by Typhoon Tokage, which killed 95 people.

Melor, which means jasmine in Malay, is the latest in a series of powerful typhoons to batter Asia in recent weeks.

In August, Typhoon Etau brought flash floods and landslides that killed at least 25 people in Japan, even though it avoided a direct hit.

Another powerful storm, Ketsana, has caused devastation across Southeast Asia, killing hundreds of people, mostly in the Philippines and Vietnam. In Taiwan more than 600 people died after Typhoon Morakot struck in August.
