Revision of guidelines for evacuation information


When you live in Japan, you must be aware of disasters. Japan is a disaster-prone country both geographically and historically.

Therefore, there are several levels of disasters in Japan, Japanese will take refuge after seeing the announcement.

In addition, each media will make reports that will cause evacuation behavior.

Hello. This is Satoshi.

There are the Great East Japan Earthquake of 3.11, the flood damage in Kumamoto Prefecture, and the typhoon at the 2019 Rugby World Cup.

I often feel that Japan is with nature.

I feel that human beings have a humble attitude to always live with nature and a feeling of compassion for each other.

On Thursday, May 20, 2021, the Basic Act on Disaster Countermeasures was revised, and evacuation information issued by municipalities changed significantly.


Announcement by the Japanese government

Revision of guidelines for evacuation information (May 3rd year of Reiwa)
Recommendations from the “Working Group on Evacuation from Disasters Caused by Reiwa 1st Year Typhoon No. 19” under the Central Disaster Prevention Council and the Disaster Prevention Measures Implementation Council were compiled in March 2nd year of Reiwa, and the system will continue based on these recommendations. In December 2nd year of Reiwa, a proposal from the “Sub-working group on evacuation information and wide-area evacuation based on Typhoon No. 19 of the first year of Reiwa” was compiled.
Based on the recommendations from the sub-working group, the Basic Law for Disaster Countermeasures was revised in Reiwa 3 (Law for Partial Revision of the Basic Law for Disaster Countermeasures (Reiwa 3 Year Law No. 30): Promulgated on May 10 In response to the fact that it was enforced on the 20th, the previous “Guidelines for Evacuation Advisories, etc.” have been revised, including the name, so that municipalities can use it as a reference when considering and amending the evacuation information issuance standards, etc. We will publish it as “Guidelines for Information”.

Evacuation order in the sure refuge.

this is the new guidelines.

Evacuation information so far,

Alert level 4 has been issued with evacuation advisories and evacuation orders, but the differences are difficult to understand and are generalized in evacuation

Please just keep it in your mind.

What you should be careful about?

Alert Level1: Raise your attitude to disasters

Increase your knowledge of disasters through books and TV coverage.
With or without this knowledge will help you decide whether to live or die.
It’s important to note that you should discard incorrect information.
This false information is very annoying.
Because you can’t prove it yourself.
If you act on the wrong information, not only will you die, but you may also involve people around you, so be sure to identify the information.

Alert Level2 Confirm your evacuation actions.


At this stage, as a preliminary step before taking action, determine your knowledge and current situation to see what you want to do.
Don’t panic at this time. If the number of people evacuating increases, you may have to consider other means than one person.
Considering that time, it is a good idea to decide on a promise that suits the situation, such as Plan A and Plan B.

Alert Level3 Evacuation of elderly people, etc.

this level is issued by the mayor of the municipality to the residents of the area where disasters are likely to occur and so that elderly people in areas at risk of disaster can evacuate to a safe place in advance.

We ensure safety by allowing elderly people who take a long time to evacuate to evacuate early.
It includes people with disabilities and their supporters.

At alert level 3, it is recommended that non-elderly people refrain from going to work, prepare for evacuation, or evacuate voluntarily, and evacuate at this stage,

Alert Level4 Evacuation Orders.

‎Alert Level 4 Evacuation orders are issued to residents in areas where the head of each municipality “considers necessary” that residents should evacuate dangerous areas in situations where disasters are imminent.‎

‎”I recognize that it is necessary” is the part that was revised under this Basic Act on Disaster Countermeasures, and before the revision of the law, residents living on the upper floors of condominiums had to evacuate collectively in areas where eviction evacuation was issued, but after the revision, evacuation orders could be issued only to people living in low-rise apartments and single-story houses in areas that are expected to be flooded.‎


Alert Level5
Emergency Safety Move to the upper floor of a nearby building.


‎In “Alert Level 5”, which is the highest level of alert, before the revision, the situation in which a disaster is actually occurring was set as alert level 5 “disaster occurrence information”, but it was pointed out that it was difficult to understand the specific action of “what should I do?”, and there were many situations where municipalities could not grasp that a disaster was actually occurring and “cannot issue” and it was not functioning effectively.‎

‎In this revision of the Basic Revision of the Basic Act on Disaster Countermeasures, “Alert Level 5” is a situation in which evacuation to a pre-set evacuation center is rather dangerous because a disaster has already occurred or is likely to have occurred, and measures should be taken by people who have been delayed in fleeing, such as when a disaster is imminent more rapidly than expected.‎

‎When “Alert Level 5 and Emergency Safety” is issued, it is required to “ensure” as close and safe a place as possible, such as a home or a sturdy building nearby. In particular, in floods and storm surges, there is a high possibility that safety can be ensured by moving to higher floors of homes and nearby tall buildings, rather than forcibly going to evacuation shelters, to high places where it is difficult to be flooded even a little.‎

With such information, Japanese people can act calmly even if they are in a disaster or if they are about to meet.

I think the Japanese are aware that causing confusion due to fear is the most damaging.

I would like to share this wisdom with you and stay safe and stay away from danger.

The notation “HINANKANKOKU” has been used for a long time in Japanese notation.
When I heard this word, it was an opportunity to start evacuation, but it is no longer used.
The word “HINAN SHIJI” has been changed, so please remember this word when checking news,
