政府、全住民収容可能なシェルター整備方針→市町村単位で対応
The Japanese government has unveiled a plan to build shelters capable of accommodating the entire population, but surprisingly, the actual development is to be handled at the municipal level.
This policy has sparked considerable skepticism online, with many questioning its feasibility, costs, and if it's merely 'passing the buck' to local governments.
Despite these concerns, there are also strong opinions emphasizing the critical importance of civilian protection during emergencies, urging serious consideration of the plan.

Civil Protection Plan
The Civil Protection Plan is a comprehensive national plan aimed at protecting the lives, bodies, and property of citizens and minimizing the impact on national life and economy in the event of armed attacks or large-scale terrorist incidents. Based on the Civil Protection Law enacted in 2004, the national government, prefectures, and municipalities are all obligated to formulate such plans. Specifically, it includes the designation of evacuation facilities, relief for evacuees, and responses to armed attack disasters. The government's new shelter development policy is positioned as part of this plan. For example, as of 2024, the Cabinet Secretariat has designated and published approximately 20,000 sturdy concrete buildings nationwide as "Emergency Temporary Evacuation Facilities," which is a prime example of an initiative based on the Civil Protection Plan. However, existing facilities are intended for temporary evacuation and have limited capacity to handle long-term stays or attacks involving nuclear, biological, or chemical (NBC) weapons. Therefore, the current discussion focuses on developing full-scale shelters capable of accommodating all residents. The government's policy of requesting responses at the municipal level stems from the principle that civil protection plans should be formulated and implemented according to local circumstances.
Underground Shelters (Nuclear/NBC-Ready)
Underground shelters, particularly those designed to withstand nuclear, biological, and chemical (NBC) attacks, are robust structures engineered to protect occupants from blast waves, radiation, chemical agents, and biological pathogens. Unlike typical basements or conventional evacuation facilities, these require specialized equipment to support long-term stays, including thick concrete walls or earth shielding, airtight doors, ventilation systems with high-performance filters, independent power generators, and substantial water and food reserves. Switzerland, for instance, has developed nuclear shelters capable of accommodating nearly its entire population since the Cold War era, with similar infrastructures also present in countries like Norway and Finland. In Japan, despite advanced underground construction techniques due to its earthquake-prone nature, specialized NBC-ready shelters are still rare in public facilities. The current policy is expected to include not only the retrofitting of existing public and private facilities but also the construction of entirely new dedicated underground facilities. When handled at the municipal level, securing construction costs, maintenance fees, and vast land will pose significant challenges, yet their necessity for ensuring national security is increasingly recognized.
Resilience (Strengthening)
Resilience is a concept referring to the ability or power to flexibly adapt and recover when faced with disasters or critical situations. It encompasses not just avoiding damage, but also quickly restoring functions even after damage occurs, and evolving into a stronger state than before. For instance, in Japan after the Great East Japan Earthquake, "National Resilience" was adopted as a national challenge, driving diverse initiatives beyond disaster prevention and mitigation, such as diversifying supply chains, improving the disaster resistance of critical infrastructure, and strengthening community cooperation. The current policy for developing shelters capable of accommodating all residents is also one of the crucial pillars for enhancing Japan's resilience from the perspective of civilian protection during emergencies. The request for municipal-level responses stems from the necessity to implement optimal resilience improvement measures based on region-specific risks (e.g., tsunami, earthquake, missile strike risks) and resources (e.g., existing facilities, land use, resident characteristics). True resilience enhancement requires a comprehensive plan that goes beyond merely constructing "structures," including securing evacuation routes, establishing information transmission systems, informing and training residents, and providing post-evacuation life support.
