The lab anticipates disaster risks in advance and designs the disaster resilience of society.

AboutAbout the lab
Designing future disaster resilience
The Ohara Lab conducts research to reduce disaster risk and enhance society's disaster resilience.
To build a society that is resilient to disasters, it is necessary to anticipate both short-term and long-term disaster risks and to design what society should look like.
Disaster resilience consists of the following elements: the strength to avoid fatal damage, the flexibility to recover quickly, emergency response, and building back better.
Aiming to realize a society that has no regrets about disasters in the future, the lab carries out a variety of activities in Japan and abroad.
Key terms
- Disaster resilience
- A society's ability to avoid fatal damage in a disaster and recover quickly from the damage it suffers
- Recovery curve
- A graph showing how affected residents and businesses recover over time
- Near-miss cases (hiyari-hatto)
- Cases of incidents that did not lead to a major failure but gave people a scare

ResearchResearch themes
In designing a society's disaster resilience, the key is how to combine these elements in a well-balanced way. The lab works on evaluating disaster risk and resilience, visualizing risk, practical activities in Japan and overseas, and human resource development.
*Illustrative imageEvaluating Disaster Risk and Resilience
The lab studies methods for evaluating disaster risk and resilience. It represents the process by which residents and businesses recover after a disaster using recovery curves, and investigates the factors that hinder or promote recovery.
*Illustrative imageVisualizing Disaster Risk
The lab studies visualization that communicates disaster risk clearly so that people see it as their own problem ("jibungoto") and take preventive measures in advance. One example is showing river flooding in 3D.
*Illustrative imagePractical Activities in Japan and Overseas
Based on the results of risk assessment and visualization, the lab aims to plan and implement risk reduction measures on site in Japan and abroad. In recent years, it has been involved in water disaster risk assessment in the Philippines as a member of a JST-JICA SATREPS project.
*Illustrative imageTraining People Who Can Anticipate Disasters
The lab studies how to train people who can anticipate what society will look like during a disaster. It collects cases of difficulties in disaster response (near-miss cases) and develops training programs based on them.
