Educational checklist, not an official tool and not engineering or safety advice. Not affiliated with 防災庁, the Cabinet Office, MLIT, MAFF, the Ministry of the Environment or any city. It doesn't inspect buildings or predict disasters; follow official alerts and your city.
Rules as of 2026-11-02 from the 防災大臣's 緊急要請 text, the PM's Office 災害への備え page, 防災庁 / METI portable-toilet guidance, MLIT seismic pages and the MoE pet disaster pamphlet. Amounts are the official per-person rules of thumb (water 3 L, 3 meals, 5 toilet uses a day), not a guarantee of what you'll need.
What this is
A free educational checklist. It turns the five points of the 防災大臣's 「事前防災徹底のための緊急要請」 (2026-11-02) into a household to-do list, using a dated reading (as of 2026-11-02) of the request text, the Prime Minister's Office 「災害への備え」 page (drinking water 3 L per person per day, 3 days minimum, 1 week for large disasters), 防災庁 / METI portable-toilet guidance (5 uses per person per day), MLIT seismic pages (旧耐震 = 建築確認 before 1981-06-01; 新耐震木造住宅検証法 for wooden houses from 1981-06-01 to 2000-05-31) and the Ministry of the Environment pet pamphlet (pet food and water at least 5 days, ideally 7+).
What it isn't
Educational checklist built from public government guidance, not an official tool and not professional, engineering or safety advice. Not affiliated with the Disaster Management Agency (防災庁), the Cabinet Office, MLIT, MAFF, the Ministry of the Environment or any city. It does not inspect your building or predict disasters; follow your city's instructions and official alerts, and get a qualified 耐震診断 for building safety.
The amounts are rules of thumb, not a guarantee: hot weather, illness, babies, older people and pets can need more. A build year is only a first filter; only a qualified 耐震診断 tells you how strong a building is. The 2026-11-02 request is a standing call to prepare and is not a warning about any specific disaster. In an emergency, follow official alerts (J-ALERT, 気象庁) and your city's evacuation instructions.
