Bosai vs 計画de災対

"This home can last 4.5 more days." — Bosai shows your household's survival days at a glance, then helps you extend them, one small step at a time. It turns Japan's everyday preparedness know-how — household-based stockpile calculation and the "rolling stock" method — into a daily routine for ordinary families. WHAT BOSAI SOLVES ◆ "I don't know what to stockpile, or how much." Most emergency checklists are one-size-fits-all — "3 days per person" and little more. Bosai calculates the required amounts of about 70 items — water, food, toilet supplies, daily essentials — personalized to your family's size, ages, and home type. ◆ "My supplies always expire and go to waste." An expiry alert alone still ends with food in the trash. Bosai builds the whole rolling-stock cycle into the app: expiry approaching → use it in a regular meal → restock on your next grocery run. Stockpiling becomes part of everyday shopping, not a special event. ◆ "Prepper apps feel like they're made for someone else." No bunkers, no survivalist gear lists. Bosai follows the Japanese approach — prepare as an extension of daily life, with items from your ordinary supermarket. It's designed for regular families. ◆ "What if the network is down when disaster strikes?" Every feature works fully offline. All articles are stored on your device. During a blackout or with no signal, Bosai just opens and works. AT THE CENTER: YOUR SURVIVAL DAYS The home screen shows in one big number how many days your family could get by on what you have now. The target adapts to your region (e.g., 2 weeks for the U.S. West Coast), and Bosai suggests exactly one "next move" to raise your score — so you never face an overwhelming to-do list.
