At least six people have been killed after Typhoon Chaba battered South Korea, authorities said.
The southern cities of Busan and Ulsan were worst affected, as well as the resort island of Jeju.
Transport, schools, factories and the country's main port ground to a halt. Footage showed muddy floodwaters rushing through city streets.
The storm is now hitting Japan, where the meteorological agency issued warnings and flights were cancelled.
The death toll included a fire fighter in Ulsan who was helping with rescue efforts, local media reported. Four people have been reported missing.
