More than 1.9 million people are under evacuation orders as Typhoon Dujuan batters Japan
As the country approaches midnight, our Tokyo correspondent says the rain has let up after a full day of downpour - but more than 50,000 households in the region are still without power
In Kanagawa, firefighters fear a woman has been buried alive after a landslide crushed a house, while a man in Chiba was taken to hospital after being trapped while working to clear debris
Some 300 flights have been cancelled and some train services suspended
Dujuan has sustained winds of 143km/h (89mph) and gusts of up to 198km/h
The storm is the latest in a wave of storms in the Pacific, made more intense by this year's "super El Niño", which has warmed the ocean and fuelled the formation of storms

The centre of Typhoon Dujuan is still offshore to the east of the Izu islands.
Sustained wind speeds are 143km/h (89mph), with gusts of 198km/h, although the strongest winds remain offshore.
Across southern and eastern Honshu there could still be sustained wind speeds of 126km/h with higher gusts.
The typhoon will not make direct landfall but there is some very heavy rain on its leading edge that has already pushed into south-eastern Honshu.
Parts of Chiba prefecture have seen more than 500mm of rain in the last two days. Oshima Town, south-west of Tokyo, recorded 800mm.
There is plenty more rainfall to come up until Tuesday evening with another 100-200mm expected. Heavy rain across the Izu islands has led to the highest level of landslide warning.
In eastern Japan, residents have been urged to remain vigilant for further landslides, flooding, lightning strikes and tornadoes as the typhoon clears.
Rough seas will continue into Tuesday but the expected wave heights will drop from between 6-9m to 5-7m.
Dujuan continues to track away from Japan on Tuesday in a north-easterly direction, with eastern Honshu seeing the heaviest of the rain.
A much quieter day of weather is expected but disruption is likely to continue. The storm will eventually weaken and lose its energy as it moves out of the warm waters.

From power to flights, here's what's been happening:

Image source, EPAIt’s night time here in Tokyo.
We had the height of the storm with the typhoon passing by the Kanto region in the past hour but finally we’ve seen the rain let up after a full day of downpour.
I’m no longer hearing the rain battering the windows.
The government downgraded alert levels too. Tokyo was at a level 4 out of the highest level 5, but it's recently been downgraded to level 2, which is an advisory.
It’s been a long and very wet day here in Tokyo to kick off Silver Week, which is our string of public holidays.
Residents usually enjoy travels and going to events but this year's 25th typhoon has unfortunately thwarted many plans.
The typhoon seems to have passed through and hit Chiba prefecture the hardest, which is located just east of Tokyo.
Even though the rain has let up, there may be reports of damage from today.
We likely won’t know the extent until the morning as it’s completely dark now. But we’ve seen videos on social media of some cars under water and smaller landslides.
The typhoon also continues to travel along the Pacific coast, toward northern Japan. So we’ll have to watch for any damage there too.

Some research suggests that Japan has become more exposed to destructive storms in recent decades.
But climate change is not thought to be increasing the number of these storms globally, and could even make them less common in some regions.
As temperatures rise, typhoons that do form are likely to become more intense on average, however.
Warmer ocean waters mean storms can pick up more energy, leading to higher wind speeds.
And because a warmer atmosphere can hold more moisture, these storms could also bring heavier rainfall.
This year, El Niño - the natural weather phenomenon bringing warmer water to parts of the tropical Pacific - is another factor.
El Niño doesn’t have a clear effect on the total number of typhoons, but it can affect where typhoons form, their strength and which countries they hit.
Some El Niño events may expose Japan to stronger typhoons, for example.

Local authorities in Kanagawa prefecture have requested that the military deploy personnel in the city of Miura, following several landslides.
Local official Akiyoshi Suzuki tells me the military have specifically been asked to help with disaster relief.
Residents have been told to evacuate Miura, as it is currently under a level four landslide warning.
A further 300,000 people have been urged to evacuate because of Typhoon Dujuan.
In an update to its figures, Japan's ministry of internal affairs says 1,908,645 people were ordered to evacuate in six prefectures - Ibaraki, Chiba, Tokyo, Kanagawa, Shizuoka and Saitama.
The evacuations are not mandatory.
Tokyo's disaster prevention agency is warning residents to avoid basements, with the area under a level 3 heavy rain warning.
In two cartoons posted on social media, the agency explains: "Basements are prone to flooding, and since you may not be able to see outside, there is a risk of being trapped."
Water can "rush" into a basement at any moment so residents should be "extremely careful", the warning adds.
The disaster prevention agency also says to look out for manhole covers, which may dislodge and pose a danger during flooding.

As many as 50,890 households in Japan are without power, according to Tokyo's power company (TEPCO Power Grid).
Chiba prefecture is the worse affected area, with 41,130 households currently impacted.
Other regions affected by power cuts include Tochigi, Saitama, Kanagawa, Yamanashi and Shizuoka.

Sodegaura City Fire Department in Chiba prefecture has told the BBC a man in his 50s has been rescued after getting trapped while working to clear debris at a landslide site.
The department says at 15:00 local time, the worker and heavy machinery fell into a bamboo thicket.
He was then rescued approximately three hours later and has been taken to hospital, an official adds.
Hundreds of flights out of Japan have been cancelled as Typhoon Dujuan is forecast to bring record-breaking levels of rainfall.
Japan Airlines have cancelled 135 flights, while All Nippon Airways called off 140 of its flights.
The storm has led to power outages and authorities have ordered more than 1.6 million residents to evacuate across five prefectures, including the capital Tokyo.

More than 1.6 million people have been told to evacuate from their homes due to Typhoon Dujuan.
Japan's ministry of internal affairs says 1,674,084 people in Ibaraki, Chiba, Tokyo, Kanagawa and Shizuoka are subject to evacuation orders.
The evacuations are not mandatory.
Warnings: Japan's meteorological agency has issued a level five emergency warning - the highest level - for flooding and landslides in Oshima town and parts of Izu islands, which are south of Tokyo. Areas in the northern Izu islands, Chiba, Kanagawa and Shizuoka are at a level four alert, according to the weather agency.
Storm's journey: The storm has passed through the Izu archipelago and will continue to head north-eastwards, parallel to the coast of Honshu, over the next 24 hours.
Winds: Typhoon Dujuan - the region's 25th typhoon this year - is producing sustained winds at its centre of 130km/h (80mph), with gusts up to 194km/h (121mph).
Rainfall: Rain is forecast to be heavy and persistent for the rest of Monday, with up to 250mm (10in) around the Kanto region. The storm has already triggered landslides there.
Typhoon's impact: There are power outages in about 4,000 households in the Kanto region. A resident near the Meguro River tells the BBC he will be staying put on his third-floor apartment as water levels in the river swell significantly.

Yokosuka City Fire Department in Kanagawa prefecture has told the BBC they received a call from a man reporting his house had been crushed by the landslide.
A woman in her 60s, who lives in the house, may have been have been swept away and is believed to have been buried alive, says the department's Yasuhiro Kaneko.
Kaneko adds firefighters are carrying out rescue operations, noting it is still raining heavily at the scene.
Yokosuka is a city about one and a half hours south of Tokyo.

Japan's Meteorological Agency says it is "extremely likely that some form of disaster has already occurred in landslide-prone areas and similar zones" and urges people to ensure their safety "immediately", warning "there is an imminent threat to life".
"There are areas in the northern Izu Islands, Chiba prefecture, Kanagawa prefecture and Shizuoka prefecture where the situation corresponds to Alert Level 4," the agency's chief forecaster Takuya Hosomi says in a news conference.
"Please check the disaster risk in the municipality where you are currently located and ensure you evacuate before the municipality issues a Level 4 evacuation order."
It is believed that the typhoon "developed more than expected" because its movement slowed slightly in the waters off the Izu Islands, where sea surface temperatures are high, Hosomi adds.

Authorities in Chiba prefecture have warned residents to brace for heavier rains starting on Monday night - which is a few hours from now local time.
Typhoon Dujuan is expected to barrel past waters off Chiba prefecture.
Level Four alerts for heavy rain and landslides have been issued in many municipalities across the prefecture, authorities say on social media.
"Please take actions to ensure your personal safety," the post adds.
