‌Record rainfall in Japan stranded thousands of travellers at Tokyo's Narita airport on Friday, bringing floods to the surrounding area that disrupted transport, knocked out power to 20,000 homes and killed eight.

More than 360 millimetres of rain fell in 24 hours in parts of Chiba prefecture, which adjoins the capital Tokyo, inundating roads and railways during one of Japan's busiest holiday weeks.

"This case was an extremely unusual situation," Chiba Gov. Toshihito Kumagai told reporters on Friday morning. "I have responded to many disasters in the past, but I have never experienced a case like this."

The eight dead included one person trapped in a submerged vehicle, public broadcaster NHK said, citing Chiba authorities and police.

At Narita, airport staff distributed sleeping bags, water and snacks to hundreds of passengers, many of whom had bedded down ⁠on Thursday after transport disruptions stranded about 7,000 people, causing widespread chaos.

"I queued for a taxi, but the wait was four hours," said Minoru Yamasaki, a 48-year-old Chiba resident returning from holiday, ‌who had booked a hotel only to be told it could not put him up. With nowhere else to go, he returned to the airport.

An airport spokesperson said most flights were expected to operate normally on Friday.

Power outages, road closures

More than 20,000 ​homes were without power in the early hours of Friday, after rain flooded a power substation, utility Tokyo Electric Power ⁠said, while gas supply to nearly 13,000 was temporarily cut.

In Chiba city, one of the ⁠worst-hit spots, hundreds of people spent the night under foil blankets at makeshift evacuation centres ⁠in ⁠government buildings.

Some major highways in ​Chiba were shut, forcing drivers to take alternative routes that clogged traffic, said highway operator NEXCO East.

Several ​rail services were also ⁠suspended on Friday, though some services from Narita to Tokyo resumed, easing congestion at the international transport hub.

Weather authorities said the 367 millimetres of rain over a 24-hour period in Chiba exceeded the previous record of 309 millimetres set in October 2013.
