Typhoon Cimaron passed over the west of the country through to the Sea of Japan early Friday, leaving more than a dozen people injured and disrupting traffic before heading further north toward Hokkaido.
Downpours caused power outages affecting about 138,000 households in central and western Japan and grounded 60 flights to and from Osaka and Aichi prefectures Friday morning.
Although the typhoon was downgraded to an extratropical cyclone Friday afternoon, Prime Minister Shinzo Abe and the weather agency urged people to remain on alert for strong winds, rain and landslides.
