Typhoon Kompasu has killed at least three people and injured dozens injured more in South Korea.
Officials say the storm, which cut power to 130,000 homes and disrupted transport, is the strongest to hit the Seoul area for 15 years.
More than 120 flights were cancelled and power cuts hit major parts of the subway network on Thursday.
Emergency rooms in Seoul's main hospitals were packed with people seeking first aid for injuries.
The typhoon is now heading for North Korea which has already been hit hard by floods this year.
Meanwhile, Tropical Storm Lionrock made landfall in the Chinese province of Fujian, bringing strong winds and torrential rain.
Forecasters warned that the storm could trigger landslides, state-owned Xinhua news agency reported.
