Authorities said more than 2,000 people had taken refuge in shelters
A powerful typhoon that battered Tokyo overnight with ferocious winds and driving rain caused commuter chaos on Monday morning, with trains halted and more than 100 flights cancelled.
Typhoon Faxai, packing winds of up to 216 kilometres (134 miles) per hour, made landfall in Chiba just east of the capital before dawn, after barrelling through Tokyo Bay.
The transport disruptions unleashed by the storm came less than two weeks before the start of the Rugby World Cup, and delayed the arrival of the Australian team -- a reminder that Japan's typhoon season could present challenges for organisers.
Forecasters had warned of potential record wind speeds for a typhoon in the region, and non-mandatory evacuation orders were still in place at 8am (2300 GMT) for nearly 340,000 people.
Authorities said more than 2,000 people had taken refuge in shelters opened to accommodate those complying with the evacuation advisories.
More than 30 people were injured in the storm, the Kyodo news agency said, including a woman who sustained serious injuries after pillars at a golf range were toppled by high winds and hit a house.
And on Sunday night, eight surfers were rescued after being swept out to sea in high waves off Shizuoka in central Japan.
Authorities said two of the surfers were sent to hospital but none of those rescued were in serious condition.
The strong winds downed trees and power lines, with left 910,000 people without electricity in the Tokyo area on Monday morning, NHK said.
And at least 10 homes were damaged in Shizuoka, with windows shattered and cars flipped on their sides, local media reported.
Television footage showed a huge roof collapsing at a gasoline station in Tateyama, south of Tokyo, with pumps crushed underneath.
Elsewhere, scaffolding was torn from buildings and protective sheeting hung to keep construction debris off the streets was crumpled and torn by the storm.
While the damage was relatively light given the wind speeds, it was enough to cause chaos in the capital's notoriously busy morning commute.
The overland East Japan Railway train system was largely halted in the early hours of operation while tracks were checked for fallen trees and other debris from the storm.
"We need to inspect tracks and check if there is any damage," a train company spokesman told AFP earlier.
The storm also caused delays and stoppages on subway lines, leading to massive crowds at some stations in the busy metropolitan area that is home to 36 million people.
Bullet train services that were suspended during the storm were largely resumed, though some were operating on a reduced schedule. Some roads were blocked by downed trees.
Wallabies arrival delayed
And at least 138 domestic flights were cancelled, with the weather even delaying the arrival of the Australian rugby team due to arrive in Tokyo Monday ahead of the World Cup that kicks off on September 20.
The French team managed to sneak in just ahead of the typhoon and reach their training camp near Mount Fuji.
However, the Wallabies squad found their preparations disrupted by Faxai's arrival.
By mid-Monday morning, the storm had moved back offshore and was headed northeast away from Japan, back into the Pacific.
The weather agency warned that landslides were still possible in Chiba as well as the northern Fukushima region as the storm headed away from land.
Japan is used to severe tropical storms and typhoons during late summer and autumn.
Strong typhoon Krosa lashed western Japan in mid-August, bringing strong winds and torrential rain that claimed one life.
And in late August, heavy rains left three people dead when massive floods also hit western Japan.
But this year, the typhoon season coincides with the Rugby World Cup, presenting a possible headache for teams and organisers.
Tournament rules say that if a pool match has to be scrapped due to extreme weather, it is classed as a draw, which could have a major impact on what is set to be a very close competition.
