One of the most powerful typhoons to ever hit Tokyo paralysed the Japanese capital on Saturday, leaving millions confined indoors and streets deserted as fierce rain and wind killed two, flooded rivers and threatened widespread damage.

A 50-year-old man was killed near Tokyo early on Saturday in a car overturned by punishing winds, while another person died after being washed away in a car, public broadcaster NHK said. Nine people remain missing in landslides and flooding, it said.

Authorities issued evacuation advisories and orders for more than 6 million people across the country as the storm unleashed the heaviest rain and winds in years. Some 80 injuries have been reported so far, while more than 270,000 households lost power.

The storm, which the government said could be the strongest to hit Tokyo since 1958, brought record-breaking rainfall in many areas, including the popular resort town of Hakone, with a whopping 939.5 mm of rain over 24 hours.

Typhoon Hagibis, which means “speed” in the Philippine language Tagalog, made landfall on Japan’s main island of Honshu on Saturday evening. A magnitude 5.7 earthquake shook Tokyo shortly after.

Even as the typhoon moved away from the capital late on Saturday, one expert warned of further flooding as several surrounding prefectures began releasing water from dams, letting it flow downstream.

“The situation is now worse than this evening,” Nobuyuki Tsuchiya, director of the Japan Riverfront Research Center, told Reuters. About 1.5 million people in Tokyo live below sea level.

The Japan Meteorological Agency issued the highest alert level for 12 prefectures, warning of potential for once in decades rain totals. It later downgraded the alert level for several prefectures, including Tokyo.

“Damage from floods and landslides is likely taking place already,” an agency official told a news conference carried by NHK. “It is critical that people take action urgently to protect their lives and the lives of loved ones.”

Just last month, another strong storm, Typhoon Faxai, destroyed or damaged 30,000 houses in Chiba, east of Tokyo, and caused extensive power outages.

Tokyo’s Haneda airport and Narita airport in Chiba both stopped flights from landing and connecting trains were suspended, forcing the cancellation of more than a thousand flights.

Train operators suspended bullet train services extensively, while many train and subway lines in Tokyo were also down for most of Saturday. Usually bustling entertainment and shopping districts such as Shibuya and Ginza were deserted.

Tokyo Disneyland was closed on Saturday, its first weather-related closure since 1984, and supermarkets ran out of bottled water, batteries and other disaster-related goods.

Many people in and around Tokyo took shelter in temporary evacuation facilities early, before the worst of the storm arrived.
