In the aftermath of a major earthquake or flood, it’s easy to assume evacuation is the only option. But in reality, most modern condominiums in Japan—especially those built after the 1981 seismic standard update—are designed to remain structurally safe even during strong disasters. That means staying in your own home, or sheltering in place, is often not only possible but also preferable.

However, continuing life at home safely requires preparation. Here are five essential steps to help make it happen:

1. Stock Emergency Supplies at Home

Keep at least 3 days’ worth of drinking water, food, and daily necessities—preferably a whole week’s supply—for each person in your household. Include hygiene items, battery-powered lights, a simple gas cooker, and items tailored to your family’s needs (e.g., baby formula, prescription medications, etc.).

2. Prevent Indoor Injuries Before They Happen

In high-rise buildings, shaking during earthquakes can be intense and prolonged. Secure large furniture, avoid placing heavy objects on high shelves, and install shatterproof film on windows to minimize the risk of injury. The fewer injuries, the easier it is to stay home safely.

3. Plan for Elevator Outages

If elevators are out of service, residents on higher floors may need help getting downstairs or bringing supplies up. If your household includes elderly members or anyone with limited mobility, coordinate now with neighbors who can assist during an emergency.

4. Tackle Longer-Term Problems Together

Issues such as garbage buildup, sanitation, and food/water shortages will become increasingly serious over time. That’s why cooperation is key. Discuss shared strategies now—such as creating designated trash areas or pooling supplies—so your building can function as a supportive community during tough times.

5. Organize Your Community Before the Disaster

The worst time to start organizing is after disaster strikes. Form a condominium disaster response team now, assign roles, create emergency communication plans, and hold occasional drills. A little planning today can save lives tomorrow

Living through a disaster in your own home may sound daunting, but with foresight and cooperation, it’s a realistic and often safer option than evacuating. By preparing now—both individually and as a condominium community—you’ll be ready to protect not just your property, but your peace of mind.
