Typhoon Megi's death toll climbed to nine in western Japan as two more bodies were found in Kagawa Prefecture on Thursday morning.

The Meteorological Agency forecast the season's 15th typhoon will hit the northern part of the country -- either the Sea of Japan coast of the Tohoku region or southwestern Hokkaido -- early Friday, bringing more heavy rain, strong winds, rough seas and mudslides.

The discovery of the bodies of Toshie Saeki, 72, and her daughter-in-law, Kayoko, 45, in Onohara, Kagawa Prefecture, brings the number of deaths to nine in Kagawa and Ehime prefectures. The two had been missing since Tuesday evening, when they were believed to have been swept away in a flooded river.
