Berliner Boersenzeitung - Thousands stranded as heavy rain kills at least four in Japan

The torrential downpours late Thursday triggered landslide warnings and power outages, with forecasters issuing the highest-level heavy rain warning for the Chiba region for the first time.

"I never thought I'd spend the night at the airport, but it is what it is and we are learning," one stranded air traveller told NHK.

"We're never going to forget this trip," he said.

Those killed included a man in his 60s or 70s found floating in a flooded road and a 66-year-old woman stuck in her submerged car, the Chiba Prefecture Disaster Management Office said.

The third fatality was a man of unknown age found collapsed on the street, and the fourth a person of undetermined gender and age.

As of Friday noon, public broadcaster NHK reported an additional two people died, putting the total death toll at six.

Meanwhile, close to 26,000 households across Chiba prefecture were without power, the disaster management office said.

A total of 45 houses flooded in cities such as Ichikawa, Kashiwa and Sakura. Another 39 homes saw water seeping in below the floorboards.

- Trains cancelled -

A Japan Meteorological Agency (JMA) official told a news conference on Thursday that this was "shaping up to be an unprecedented level of heavy rain".

Around 6,000 people were stranded overnight at Narita, one of two main airports serving Tokyo, with many trains to and from there cancelled until Friday afternoon, the Chiba disaster office said.

At Narita, sleeping bags piled up as passengers slept all over the terminal, with massive lines forming for check-in across the airport.

A traveller from the United Kingdom who gave his name as Philip told AFP that he had to go through a nine-hour journey, including a taxi ride, before finally arriving at the airport early Friday morning.

With a sleeping bag in hand, he said he has "just been trying to get some sleep and watching Netflix now".

"Just get on with it, really. Nothing else you can do," he said.

Users on social media said that airport staff handed out free water, food and sleeping bags.

Hundreds of people were also left stranded in Chiba station due to suspended train services, an AFP journalist saw.

Hundreds spent the night in shelters in Chiba, NHK reported, showing cars in water up to the headlights in Kashiwa city.

"This happened all of a sudden, so it was a complete surprise. The power is out, so I'm worried whether I can open my business in the next couple of days," a woman in Chiba's Ichikawa city told NHK on Thursday.

The level-5 warnings of heavy rain were all downgraded to level-4 as of Friday morning.

Scientists say human-driven climate change is making extreme weather more frequent, prolonged and intense.
