Heavy rain triggered extensive flooding in the northeastern Japan prefecture of Yamagata through Wednesday morning after a river burst its banks at several locations.
While no casualties have been reported, the prefectural government has been trying to assess the extent of flood damage along the Mogami River, which began to overflow late Tuesday.
The land ministry has confirmed the river breached its banks at three locations in the town of Oishida as well as in Okura village, with at least 80 hectares of land inundated by Wednesday morning.
The Mogami River is the seventh longest river in Japan and the river basin accounts for about 75 percent of Yamagata Prefecture.
