CeMI's Mission Statement

Japan faces many natural disasters triggered by earthquakes, volcanic activities, tsunami, storm surge, typhoons, torrential rain as well as societal (human) disasters caused by fires, ground subsidence, pollution and environmental degradation. These threaten a great many lives, and have a massive impact on social infrastructure.


It is a pressing concern for Japanese society that the various organizations involved in disaster risk reduction can align with each other to create a new body of knowledge to share with citizens, and through this approach to form a disaster-resilient society in which citizens can be active participants. To mitigate the severity of disasters, the knowledge of disaster risk reduction held by individuals along with societal interest in environmental and disaster risk reduction issues must be elevated in each household, school, workplace and at the community level.


To expedite this, we must engage with citizens broadly, carrying out research, surveys and educational initiatives regarding environmental conservation and disaster risk reduction. By promoting public-awareness-raising, we aim to contribute to resolving global environmental issues and to improving the resilience of communities to disasters.


CeMI (Crisis and Environment Management Policy Institute), a Specified NonProfit Corporation, was established on February 27, 2004, with the approval of The Cabinet Office.

Designed "Personal and family time-line to brace for typhoons"

The onset of the typhoon season marks a period where disasters often occur. We designed a "Personal and family time-line to brace for typhoons", that lays out typhoon countermeasures that can be implemented by families and individuals.


*These are examples of countermeasures summarizing the bare minimum amount of preparation/response actions to be taken when a typhoon is approaching. It should be tailored and utilized in line with the unique circumstances of individuals/families.

*A timeline is a method for minimizing damage from typhoons and other such disasters that prescribes how to respond in chronological order, from the time of onset of the disaster right up until it is close by. It is a method that has been adopted by municipalities across Japan.

Outline of personal and family timeline for bracing for typhoons:

3 days ahead "Confirm evacuation site/evacuation route", "inspect house and vicinity"

2 days ahead "Confirm method of making contact with those in vicinity", "Confirm bulk purchasing, emergency supplies kit"

1 day ahead "Begin evacuation for families who require extra time"

12 hours-several hours ahead "Begin evacuation for all family members"

The following points are vital for minimizing damage sustained by your family during a typhoon:

・Hold regular discussions with your family and decide the precise roles and duties of each family member during the onset of a disaster.

・When a typhoon is approaching, make every effort to carry out the duties decided during family discussions in appropriate manner, in line with the circumstances.

・In order to accurately ascertain the situation, pay close attention to typhoon information and also monitor weather forecasts, river warnings and evacuation orders etc.

Report regarding on-site survey of Kanto/Tohoku torrential rain of September 2015

Field investigation into state of area where Kinugawa River levees burst on September 10, 2015.

The area around where the levees burst is a quiet rural area interspersed with former settlements and rice paddies, along national route 357. However, the flood flow from the destroyed levees completely changed this scenery.

You can appreciate the sheer enormity and power of the flood flow, by looking at the state of damage to buildings, roads and houses.

Publicizing of "Proposal for deliberating Timeline for responding to levee collapse in the Shonai River"

Currently, MLIT (Ministry of Land, Infrastructure and Transport) is implementing "leading projects" in the Tokyo Metropolitan region and the Chubu Area to support promoting the timeline method. As one spoke of this project, to safeguard the Nagoya area where many lives and assets are concentrated in the Shonai River basin from disasters, Nagoya City and private companies that operate the subway system are working together to formulate a Shonai River Timeline.
A planning team was appointed in June 2014 toward formulating the Shonai River Timeline, and since then workshops and discussions were held for formulating a timeline to safeguard citizen's lives. This included DIG (Disaster Imagination Game) utilizing a timeline - the first in Japan - as well as verification of flood season, with the aim of creating a highly applicable and practical timeline.

CeMI is providing planning support regarding the formulation of the Shonai River timeline.

In March 2015, we publicized the "FY2016 Proposal for consideration of timeline for levee failure in the Shonai River", which paved the way for flood damage disaster response implemented through linkages between various bodies/organizations using a timeline.

Timelines save lives!

Matsuo Ichiro, Deputy Director, CeMI


In late 2011, the New Jersey State Crisis Management Division began formulating a timeline as an appendix (code of conduct) to the State Government's Crisis Response Plan. They felt that there were some issues with the disaster response to Hurricane Aileen in 2011, and identified the timeline to prescribe preventative action for hurricane disasters as one improvement measure. It was first put into action in October 2012 during Hurricane Sandy.

As part of a survey into crisis management during Hurricane Sandy, the author (Ichiro Matsuo) met with State Government Crisis Response Officers to learn about the system and its effectiveness, with a view to applying this to typhoon disasters in Japan.

Currently, initiatives toward its adoption are taking place in national government organs as well as local municipalities. It is sincerely hoped that this code of conduct will function to promote better linkages between organizations and to clarify the roles of each body, in order to safeguard the lives of one and all from typhoons.

We intend to provide regular updates and commentary on this website regarding the deliberation process and developments.
