Preparation for typhoon and heavy rain
Last update date December 27, 2023
Check 1. Daily Preparation ~ Let's prepare in case of emergency~
Let's check your home and shelter on the hazard map!
- Make sure that there is no risk of flooding near your home.(Flood Hazard Map)
- Make sure there are no cliffs near your home (Earth and sand disaster hazard map）
- Write the evacuation route from your home to the evacuation center on the map. （evacuation sites during storm and flood damage）
Care should be taken when considering evacuation routes
- Check multiple evacuation routes so that you can evacuate to two or more evacuation centers.
- Avoid roads that may be closed due to flooding due to heavy rain or landslides.
Let's check the items to be taken out during evacuation!
- Prepare items to be taken out during evacuation on a daily basis so that you can take them out immediately.
- The items to be taken out should be kept to a minimum. (Radio, drinking water, flashlights, pharmaceuticals, baby products, etc.)
Let's work together to protect our town!
- In the event of an emergency, cherish your relationship with your neighbors on a daily basis so that you can help each other.
- Let's create a system that can cooperate in the community to protect the safety of people who have difficulty responding flexibly, such as evacuation behavior in the event of a disaster due to disability or elderly people.
- Let's talk about the cooperation system in the event of a disaster for nearby social welfare facilities in the area on a daily basis.
- Let's hold disaster drill, evacuation drill and lectures to acquire knowledge about disaster prevention.
- When evacuation warning comes out, call out to the neighborhood and take the initiative in evacuating.
Check 2. When heavy rain comes ~ Let's pay attention to this point~
Let's try to gather information frequently on your own!
Please check the information frequently on the Japan Meteorological Agency website and the Yokohama City website.
- Japan Meteorological Agency website (weather information) (outside site)
- Yokohama City Disaster Prevention Information
Be especially careful when landslide disaster alert information comes out.
About earth and sand disaster caution information, this (JMA homepage) (outside site)
Let's pay attention to the cliff!
A precursor to a landslide
- Pebbles fall from the cliff.
- New spring water is generated on the slope.
- There is a turbidity of the spring water.
- There is a crack in the slope.
If any of the above precursory phenomena occur, take evacuation actions as soon as possible.
In addition, there may be cases where there is no time between the occurrence of a precursor phenomenon to the occurrence of a landslide, or there is no precursor phenomenon.
If you feel danger, take evacuation actions as soon as possible.
Check 3. When evacuation information comes out-Evacuation action to save lives-
Don't overdo it and try to evacuate safely!
When evacuating, wear easy-to-move clothes and try to act with two or more people.
Evacuation is about avoiding difficulties, and going to evacuation sites is not the only evacuation behavior.
If the surroundings are dark and flooding has already begun, please do not force yourself to go out and consider "evacuation at home" to stay in a high place where safety can be secured at home, such as the second floor of home.

Let's evacuate on a safe route!
- When evacuating, avoid roads along rivers, cliffs, and underground roads.
- The gutters and manhole covers on the road may be off due to heavy rain, so be careful and stay away.
The name of the evacuation information has been partially changed.
Following the damage of Typhoon No. 19 in 2019, the Cabinet Office considered storm and flood damage countermeasures, and the revised "Basic Law on Disaster Countermeasures" was enforced on May 20, 2021, and the "Evacuation Information Name" at the alert level was changed. I will let you know.
