Staying Safe in Severe Weather

Michelle Cunniff • Nov 19, 2021

In recent years, Japan has experienced an increasing number of severe weather events throughout the country. In the case a need for evacuation arises, it is important to be prepared and stay well informed of the situation. In this article, we want to give you some basic information about how to stay informed and be prepared in case of an emergency.

Know your potential risks

When moving to a new area, it is important to learn as much as you can about your community. This includes identifying if your area is prone to certain weather patterns, and if there are any areas in your neighborhood that have a higher potential for needing evacuation during severe weather. Your local Ward Office or Town Hall can be a great place to find resources for emergency information, such as:

  • Flood risk areas
  • Tsunami risk areas
  • Landslide risk areas
  • Evacuation shelter locations
  • Etc.

Potential risks should be highly considered when creating your evacuation plan. Please keep these in mind when confirming your safe routes, and determining the evacuation timing that will work best for your situation.

About the weather advisory system

The Fire and Disaster Management Agency currently uses a 5-level alert system to guide residents about what to do in case of emergency. These are classified as:

Level 1 (White): Possibility of upcoming weather warnings.
Level 2 (Yellow): Heavy rain, flood, or storm surge advisories.
Level 3 (Red): Advisory to prepare for evacuation (General Public) / Evacuation Order for elderly and those requiring additional time or assistance.
Level 4 (Purple): Evacuation Order for all residents.
Level 5 (Black): Disaster in progress (take immediate action to ensure your safety).

The designated colors will often be depicted over a map of Japan on local news channels and weather sites to indicate the warning levels for different areas of Japan when severe weather is predicted.

When to prepare for evacuation

It is highly recommended for all households to always have an emergency kit prepared with at least 3 days’ worth of food and water per household member, along with a general stock of daily goods for about 1 – 2 weeks. If you are aware of the potential of severe incoming weather, it would be a good idea to double check your items a few days in advance, and make sure you have everything you may need before the storm hits.

When to evacuate

For the elderly, young children, or other residents who may need additional time or assistance for evacuation, it is recommended to begin evacuating once a level 3 advisory is announced.

For the general public, all residents should be in the process of evacuating as soon as possible once a level 4 advisory is reached. 

Level 5 is generally only used when immediate action is needed to ensure safety, such as sheltering at home or in the nearest safe structure. At this stage, it is often considered unsafe to travel to a designated shelter. Additionally, as it may not be possible for the full scope of a disaster to be known in real-time, please be aware that level 5 may not always be announced in the case of a sudden change in situation.

Evacuation locations are often set up in locations generally intended for public use, such as local schools, public halls/community centers, public parks, etc. Accessible locations may differ depending on the type of disaster or your individual needs.
