As an ordinary family who experienced the 3?11 Great East Japan Earthquake in Tokyo, my daily disaster preparedness stockpile is as follows for reference. Items to be kept in a backpack and readily accessible: Proof of identity (ID card, passport, etc.) A certain amount of cash (Including some coins. This can be used at coin-operated telephones and vending machines.), passbook and ticket card Emergency cell phone charger Family photos (for contact in case of separation) Contact book (copy down important phone numbers in case your cell phone runs out of battery, malfunctions, etc.), paper, grease pencil (for leaving messages, taking notes, etc.), flashlight (1 regular, 1 hand-cranked power generator), and batteries Radio (for outside information) and batteries Tissue paper/wet wipes/sanitary napkins (also useful for stopping bleeding), aluminum foil, and batteries. Aluminum foil (1.5x2m for insulation, warmth and waterproofing) Several plastic bags (for garbage, dirt/wind/waterproofing/) Whistle (for survival) Swiss Army Knife Atlas A few energy bars, a bottle of water Reserve Food: Reserve Food (mainly: rice; canned goods (fruit/fish/meat) that don't require a can opener; boxed rice; compressed cookies with a 5-year shelf life; chocolate; curry paste; instant noodles; instant coffee; instant noodles; canned food; canned food; instant coffee; canned food; instant noodles; instant coffee; instant noodles; instant coffee; instant coffee; instant coffee; instant coffee; instant coffee; instant coffee; instant coffee; instant coffee; instant coffee. sauces; instant noodles; instant coffee and tea) Reserve water (20 liters. Based on 3 liters of water per person per day, it can sustain two people for three days) Items to cope with life in a long-term refuge: candles, matches, lighters (for lighting) cassette stoves + gas canisters (you can cook and eat even if the gas stops) hats (if the water is cut off there may be no water to wash your hair for days on end, and the hats can keep you warm/prevent dust) commonly used medicines (e.g., antihypertensive drugs/anti-inflammatory medicines for the elderly/fever-reducing drugs/anti-diarrheal medicines/band-aids) rain gear (folding raincoats) Buckets and other containers that are easy to carry (the government will have water trucks to supply water when there is a water outage, but containers are a problem) Cotton gauze gloves (for protection at the site after a disaster) Books/cards (life without electricity is boring ......) The above have been slowly filling up over the past year. Dust masks, face masks, and other disaster prevention items have little to do with earthquakes, so I won't include them. We can see what else can be added.
