Inagi City Evacuation Information Judgment and Communication Manual

In March 2019, the Cabinet Office revised the "Guidelines for Evacuation Advisories, etc." published in 2017, using the lessons learned from the heavy rains in July 2018. The aim is to enable residents to take evacuation actions based on their own judgment with the awareness that "they must protect their own lives." The guidelines categorize the actions residents should take into five levels of alertness, clarify the relationship between weather information and alert levels, and enhance the content to support residents' voluntary evacuation decisions, making evacuation actions more intuitive based on the information using alert levels.

The city has revised the "Inagi City Evacuation Advisory Guidelines" as the "Inagi City Evacuation Advisory Judgment and Communication Manual" in accordance with the "Guidelines for Evacuation Advisories, etc.".

In May 2021, based on the lessons learned from Typhoon No. 19 in 2019, the Basic Disaster Management Act was amended (promulgated on May 10, 2021, and enforced on May 20, 2021). The five levels of alert have been improved to allow residents to make quicker evacuation decisions, consolidating alert level 4 into "Evacuation Instructions" and defining alert level 5 as "Emergency Safety Assurance."
