❓ What is changing?
A "Bosaicho (Disaster Management Agency) Preparation Office" has been set up inside the Cabinet Secretariat to prepare the launch of a new central government agency dedicated to disasters. Two laws underpin it: the Bosaicho Establishment Act (Act No. 61 of 2026) and the Act on Arrangement of Related Acts Accompanying Enforcement of the Bosaicho Establishment Act (Act No. 62 of 2026). Both were promulgated on July 17, 2026.
The day the agency actually starts operating will be fixed separately by a Cabinet Order setting the enforcement date. Draft outlines and texts of that order, of the Bosaicho Organization Order, and of an order arranging related Cabinet Orders are published on the Cabinet Secretariat page, but their order numbers are still blank — meaning they are not finalized yet.
The stated reason is the government's assessment that national-crisis-scale disasters such as a Nankai Trough earthquake or a Tokyo inland earthquake are imminent. The overall direction is laid out in the "Basic Policy for Promoting a Disaster-Resilient Nation" (Cabinet decision of December 26, 2025), which puts human life and human rights first.
Until now, overall coordination of disaster policy sat with the Cabinet Office's disaster management section, and preparedness in normal times, emergency response, and reconstruction were handled in separate phases. The key difference is that the Bosaicho is designed as a single command function covering the whole span — from peacetime preparation through recovery and reconstruction. During preparation, a Ministerial Meeting for Promoting a Disaster-Resilient Nation (Cabinet Office) and an Advisers' Meeting are in place, and the outline of the FY2027 budget request has been published.
🌏 Impact on foreign residents and visitors
In a disaster, foreign residents often have to make decisions without being able to read Japanese-language warnings or knowing how evacuation shelters are run — which is exactly how people end up evacuating too late or missing out on support. The "human life and human rights first" stance behind this preparation points toward handling people with limited Japanese and different residence statuses through one command function, from peacetime through reconstruction.
For now, though, this is the organization-building stage: the counters you use for evacuation and victim support do not change today. If an earthquake, typhoon, or heavy rain hits you now, the sources remain the same — the Cabinet Office disaster information page, the Japan Meteorological Agency's multilingual information, and your city or ward's disaster app and hazard map. Because the start date and the transfer of jurisdiction are to be set by Cabinet Order, watch for the orders as they are promulgated and for notices from your local government.
