Moving to Tokyo for college or a new job is an exciting milestone. Many of you may choose to start your new life in Adachi Ward—specifically around lively hubs like Kita-Senju, Ayase, and Kita-Ayase. While selecting furniture and exploring local restaurants is thrilling, there is one vital task you must handle on your very first day: preparing for disasters.
Japan is a country where natural events like earthquakes and large summer typhoons happen. If you are living away from home for the first time, developing a "self-defense" mindset is essential. In this guide, we will walk you through how to read Adachi Ward's hazard maps, outline smart evacuation steps, and provide concrete advice to ensure your safety.
Floods and earthquakes do not have to be disasters if you know where and how to evacuate beforehand. Bookmark this page on your smartphone and compare it with your own living environment today.
💡 Quick Summary: Key Points
Adachi Ward Flood Risk: Since the area lies between the Arakawa and Nakagawa rivers and contains low-lying ground, early evacuation (horizontal or vertical) is critical during flooding.
3 Rules of Disaster Preparedness: Check the estimated flood depth for your apartment, stockpile at least 3 days of food/water, and download the Tokyo Disaster Prevention App.
Evacuation Decisions: Shelter in place during earthquakes. During floods, take early horizontal evacuation if on the 1st floor, or vertical evacuation if in a sturdy building on the 2nd floor or higher.
1. Understanding Adachi Ward's Geography and Why Hazard Maps Matter
Understanding the geographic layout of your new neighborhood is the first step toward effective disaster preparedness.
Adachi Ward is flat and water-rich, bordered by the Arakawa River to the west and the Nakagawa River to the east, with the Sumida River flowing south of the ward. While this flat terrain makes walking and daily life convenient, some parts of the ward lie below sea level, meaning you must prepare for flood risks during super typhoons or historic torrential rains.
Hazard maps provided by local municipalities use historical data and scientific simulations to color-code and visualize where and how deep flooding could occur. Checking these maps is not about inducing fear; it is the most reliable database for maximizing your survival during an emergency.
2 Key Maps You Must Check
Arakawa River Flood Hazard Map: Shows the simulated flood levels in the worst-case scenario where the Arakawa River embankment collapses. It outlines how floodwaters would spread, including across the Kita-Senju area.
Earthquake Disaster Map: Helps you identify the safest routes to designated "Wide-area Evacuation Sites" where fire risks and building collapse risks are low.
You can easily check these maps on your smartphone via Adachi Ward's online interactive disaster prevention map. Be sure to check the color (estimated flood depth) for your apartment, daily commute route, and nearest station.

3. Smart Evacuation Actions Tailored to Earthquakes vs. Typhoons
In Japan, your evacuation actions must be completely different depending on whether you are facing a "sudden earthquake" or a "predictable typhoon (flood)."
① Earthquake Action: Protect Your Head and Shelter in Place First
When an earthquake hits, running outside immediately is dangerous due to falling glass or roof tiles.
Basic Action: Protect your head with a cushion or get under a sturdy desk. Wait until the shaking completely stops.
Check Fire Sources: Once shaking stops, turn off stoves, heaters, and gas valves to prevent fires.
Prepare for Exit: Open the front door to secure an evacuation route, grab your emergency backpack, and calmly walk to the designated wide-area shelter.
② Typhoon/Flood Action: Act Early Based on Your Apartment Floor
Flooding from typhoons and heavy rains is predictable. Early decision-making is key.
If on the 1st Floor / Semi-basement (Horizontal Evacuation): If your room is on the 1st floor and the hazard map shows a flood risk of 1m or deeper, evacuate early to a designated shelter (local schools or solid public buildings) before the water starts rising.
If on the 2nd Floor or Higher in a Sturdy Concrete (RC) Building (Vertical Evacuation): If the roads are already flooded, walking outside is extremely dangerous. In this case, shelter in place by moving to upper floors and wait for rescue/utilities restoration.
