Actions and Driving Precautions for a Level 5 Heavy Rain Special Warning

Following the torrential rains in Chiba in August 2026, flyers were prepared on the actions to take when a Level 5 Heavy Rain Special Warning is issued and on driving precautions when the warning is issued.

The publication was made jointly with the Cabinet Office, the National Police Agency, and the Fire and Disaster Management Agency.

The use of these flyers is being encouraged to promote broad public awareness and help reduce damage caused by heavy rain.

The published materials consist of two types of flyers: one titled Actions to Take When a Level 5 Heavy Rain Special Warning Is Issued and the other titled Driving Precautions When a Level 5 Heavy Rain Special Warning Is Issued. Both are presented as materials concerning situations in which a Level 5 Heavy Rain Special Warning is issued.

The listed contacts are the Disaster Management Division of the Water and Disaster Management Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, the Disaster Management Planning Office of the Planning Division of the General Affairs Department of the Japan Meteorological Agency, and the Operations Division of the Atmospheric and Oceanic Department of the Japan Meteorological Agency. The contact information includes telephone numbers, extension numbers, or direct numbers.
