Japan is preparing for Typhoon Vongfong which is due to hit the country late on Saturday.
The southern island of Okinawa is likely to bear the brunt of the storm.
Storm tracking website Tropical Storm Risk shows Vongfong losing power as it moves northeast to the rest of Japan.
An official from Japan’s Meteorological Agency told Reuters news agency: "There is no question that (Vongfong) is an extremely large, extremely powerful typhoon."
"It’s the strongest storm we’ve had this year, definitely, although it has lost some strength from its peak."
Earlier this week, parts of Japan were hit by Typhoon Phanfone, though that storm had rapidly lost power by the time it hit Tokyo on Monday.
Japan’s Kyodo news agency said nine people are now known to have been killed by Phanfone, including three US military servicemen in Okinawa who were washed out to sea. Their bodies have since been recovered.
