Typhoon Faxai, which made landfall early Monday morning in the coastal city of Chiba, brought heavy rain and winds of 120 miles per hour, according to the Japan Meteorological Agency (JMA).
The storm then moved over Tokyo and paralyzed transport. Major subway stations in Tokyo were crammed full of commuters on Monday morning, all stuck waiting for bullet trains and subway services that had shut down.
The train services gradually resumed mid-morning, but all lines are still experiencing delays.
More than 100 flights to and from airports in the Tokyo area were canceled on Monday, including 49 Japan Airlines flights and 41 by All Nippon Airways, according to the airport website. The entire Keikyu rail line, which connects Tokyo and Yokohama to Haneda Airport, is still suspended.
As of Monday afternoon, 6,800 passengers were stranded at Narita International Airport, according to an airport spokesperson. Flights are still arriving, but with highways blocked and two railways to the city center shut down, arriving passengers had no way to leave the airport.
Narita is one of two international airports in the Tokyo area.
Photos show flooded streets, littered with downed trees and branches. Workers on Monday tended to signposts and lamps that had blown over, and employees at the Higashi Chiba train station inspected the roof, which was twisted and torn apart.
So far there have been no deaths reported, but at least ten people have been hospitalized, NHK said on Monday.
Ahead of the typhoon, JMA issued storm surge, flood, and landslide warnings, and asked the public to avoid going outdoors.
