What are weather and disaster alerts?
In Japan, the Japan Meteorological Agency (JMA) issues official alerts when dangerous weather or a disaster is expected. They tell you how serious the situation is, so you can decide what to do. Alerts come in levels, and the stronger the word, the more dangerous the situation.
The main levels
Alerts generally rise through three stages.
Advisory /
注意報 (chuiho)
Conditions could cause minor problems.
→ Stay aware and check updates.
Warning /
警報 (keiho)
Dangerous conditions are expected.
→ Avoid unnecessary travel.
Emergency Warning /
特別警報 (tokubetsu keiho)
Used for rare, extreme events.
→ Act now to protect yourself.
Power outages
Earthquakes and heavy snow can both cut the power, sometimes across a wide area. In 2018, a large earthquake left almost all of Hokkaido without electricity. In winter, a power outage is especially serious because it also stops the heating — staying warm becomes a safety issue, not just a comfort one.
Prepare in advance
Keep your phone charged and carry a power bank.
Have some cash — cards and ATMs may not work.
Keep a flashlight or light source handy.
If the power goes out
Check official information (JMA, NHK WORLD, the Safety tips app) for updates.
Save your phone battery, but keep it on for alerts.
If your room becomes unsafe, move to a designated shelter or a large public facility.
