According to a survey by the Ministry of Land, Infrastructure, Transport and Tourism, about 40% of public housing in Japan is built in areas where there is a risk of flooding due to heavy rain and tsunami.
From this year, the government plans to subsidize part of the cost of removing public housing, and hopes to help eliminate disaster risk.
The Ministry of Land, Infrastructure, Transport and Tourism investigated the risks of disasters in places where public housing managed by local governments nationwide is located through municipalities from October to December last year.
As a result, it was found that some kind of disaster risk is assumed in 14,573 places, which is 44.2% of the 32,000 housing estates.
By type, 8688, which has the largest number of flood inundation areas such as river floods, 4853, storm surge inundation area, 2017, and tsunami area, 1241.
Due to the flooding of rivers in the heavy rains in western Japan in 2018 and the typhoon in eastern Japan in 2019, public housing has been inundated and residents are forced to live in evacuation. The policy is to subsidize part of the cost when removing.
Associate Professor Yasunori Hata of the University of Yamanashi said, "The significance of visualizing the risks of public housing is great. First, it is important for the residents themselves to know the risks, and then soft measures such as evacuation drills should be taken. Population decline progresses. In particular, the government needs a direction to develop high-quality housing in a safe place, and national support is desired. "
The results of this survey do not include the number of metropolitan housing in Tokyo.
He explained that the number of capitals is too large to grasp the actual situation, and he plans to grasp the actual situation within this fiscal year.
