Japan is bracing for a powerful hurricane called a typhoon in this part of the world.
The storm called Chan-hom will cause heavy rainfall, flooding, landslides, mudslides and high waves, the meteorological agency warns.
The slow-moving typhoon has already reached some islands southwest of the mainland. There, gusts of wind of up to 180 kilometres per hour have been measured.
The storm is expected to reach the capital of Tokyo and the surrounding area on Saturday evening.
In July, heavy rains wreaked havoc on Kyushu Island and in central parts of Japan, killing about 80 people.
