Areas in eastern Japan ravaged by last weekend's massive Typhoon No. 19 are bracing for more rainfall from late Friday through early Saturday afternoon, with heavy rain feared in some locations.
Even a little rain could cause flooding or mudslide disasters in areas where the ground was loosened by the typhoon or where flood banks were washed away.
The Japan Meteorological Agency has called for residents to be careful about swollen rivers, flooding and submergence of low-lying areas. Relevant municipalities and those affected by the disaster are increasingly anxious about the prospect of more rain.
According to the JMA, total rainfall from 6 a.m. Friday through Saturday midnight was expected to reach 200 to 300 millimeters in the Izu Islands, 100 to 200 millimeters in the Tokai region, 100 to 150 millimeters on the Pacific Ocean side of the Tohoku region and the Kanto-Koshin region, and 50 to 100 millimeters in the Hokuriku region. In Miyagi and Fukushima prefectures, heavy rainfall of 30 millimeters per hour is feared on Saturday morning.
In the Hoyasu district of Nagano, where the Chikumagawa river experienced a levee burst, a makeshift bank was completed at a point at around 11:50 p.m. Thursday. After the levee break, a large area up to about 9.5 square kilometers in the district and surrounding areas were flooded, damaging about 1,800 households.
The Land, Infrastructure, Transport and Tourism Ministry plans to conduct temporary restoration work, elevating the place where the bank was broken by about five meters and installing iron plates on the river's side of the makeshift bank. The ministry will then begin full-scale restoration work.
