Strong winds brought on by a low pressure system hovering over Japan hit the nation's eastern and central regions Friday, injuring 17 people and disrupting transportation services in the Kanto and Tokai regions, officials said.

The Kanto and Koshin regions in eastern Japan, the Hokuriku region along the Sea of Japan coast, the Tokai region in central Japan and the Kansai region in western Japan have now entered the rainy season, the Meteorological Agency said.

The Chugoku region in western Japan entered the rainy season Thursday. The Kyushu and Shikoku rainy seasons began last Saturday.
