Japan is intensifying national efforts to enhance disaster resilience and infrastructure stability following significant natural disasters. Initial government strategies focused on institutional and structural reorganization, including the planned establishment of a ‘Disaster Prevention Agency’ and the passage of the ‘Sub-Capital Creation Law’ to decentralize national functions. Digital resilience has also been prioritized through initiatives like ‘00000JAPAN’, which provides emergency Wi-Fi access to disaster victims. Subsequent efforts have expanded into specific infrastructure management and public-private partnerships. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is broadening the scope of river works to include the Sea of Japan coast and inland regions to counter earthquakes and storm surges. In Osaka, local authorities are pursuing new models to accelerate the replacement of aging, seismically vulnerable water pipes. While the government is attempting to stimulate private investment for crisis management, the construction sector faces headwinds, with many companies reporting project delays due to labor shortages and rising material costs. Reflecting on historical disasters, such as the Kii Peninsula floods and the Tokai Heavy Rain, regional strategies have evolved toward ‘basin-wide flood control’ and the use of disaster timelines to coordinate evacuations. In Nagoya, increased rainwater storage capacity—which has grown fivefold through adjustment ponds—has helped reduce fatalities during recent extreme rainfall. However, experts caution that sustained, extreme precipitation may still exceed current infrastructure limits.
