Japan's land ministry says the Mogami River in Yamagata Prefecture has overflowed its banks late Tuesday due to record rainfall in the country's northeastern part. The ministry is calling on residents to be on the highest alert.
Weather officials say more than 200 millimeters of torrential rain was recorded during a 24-hour period through Tuesday night in some parts of Yamagata Prefecture in the southern Tohoku region.
At least 15 rivers in the prefecture overflowed at one point.
In the Tohoku and Hokuriku regions, as much as 100 millimeters is forecast in the 24-hour period through Wednesday evening.
In Niigata Prefecture, the edge of a road collapsed causing structures to fall down a slope.
Weather officials are urging people to be on the alert for landslides and overflowing rivers especially in Yamagata Prefecture.
