The third major storm to hit the Korean Peninsula in two months uprooted trees and left at least two people dead in landslides.
More than 260 flights were cancelled and ferry service was halted across the south.
The typhoon raked South Korea’s capital of Seoul with high winds and driving rain that forced the cancellation of all first-round matches at the WTA Korea Open tennis tournament.
The storm weakened considerably before drenching North Korea and Russia’s Far East.
There were no immediate official reports from North Korea on whether the storm caused any significant damage or fatalities there.
Typhoons Bolaven and Tembin, which struck the peninsula in late August, killed more than 20 people in South Korea.
They damaged farmland and hundreds of houses and caused power failures that affected millions of homes.
