Japan’s disaster management minister urges the public to stockpile food and water

Japan’s disaster management minister, Goshi Hosono, said that when the newly established Disaster Management Agency launches on November 2, 2026, he will issue an “emergency request” to all citizens, central ministries and agencies, and prefectures, urging them to advance disaster preparedness. He called on households to keep at least three days’ worth, and preferably one week’s worth, of food, water and toilet supplies at home so they can cope even without public assistance.

Hosono made the remarks in an interview on a Fuji Television program. He referred to risks such as a Nankai Trough earthquake, a Tokyo inland earthquake, major earthquakes along the Kuril Trench and Japan Trench, and a Mount Fuji eruption, and stressed improving shelter conditions, including toilets, kitchens, beds and bathing facilities. The request is in line with existing Japanese government guidance: households should stock at least three days of essentials, ideally one week; the standard for drinking water is three liters per person per day.

Supporting content: Supports the English-side paraphrase of Hosono’s appeal, the call to stockpile for at least three days, and the November 2 launch of the Disaster Management Agency.

This “emergency request” is synchronized with the formal launch of the Disaster Management Agency and is intended to reinforce existing household stockpiling guidance rather than introduce a new standard. The Japanese government has long recommended that households prepare at least three days’ worth, preferably one week’s worth, of food, water and daily necessities, with three liters of drinking water per person per day. Hosono’s emphasis on being able to cope without public assistance points to the reality that initial public support may be delayed after a major earthquake.

The Disaster Management Agency is positioned as a central command body for disaster response. Hosono also placed emphasis on improving shelter conditions (the TKBB framework), showing that the policy combines household self-help with public facilities. The risks mentioned include the Nankai Trough, a Tokyo inland earthquake, trench-type earthquakes and a Mount Fuji eruption, all of which are existing disaster scenarios in Japan.

Unlike simple publicity, this ties the timing of the request to the launch of the new agency and expands it to ministries, agencies and local governments. The actual effect will depend on subsequent formal documents, local implementation and public response. Similar guidance in the past has led to short-term panic buying after earthquake warnings, but the government has also stressed avoiding excessive stockpiling.

This move continues Japan’s disaster-preparedness system, which centers on household stockpiling. For the public, the three-day to one-week quantitative standard already exists; this request mainly serves as a reminder and policy signal. The final degree of stockpiling will still depend on individual habits and supply-chain conditions.

Linking the existing stockpiling standard to the launch date of a new agency is a policy reminder rather than a new mandatory requirement.
Household self-help stockpiling and shelter-condition improvements are both listed as priority items for the Disaster Management Agency.
