Increase in exposure : Population and assets are concentrating to hazardous area
Vulnerability : Population and assets have not enough resistance against natural hazards

Benefit of Mitigation can be different. It depends on the possibility of risk transfer [ Kobayashi & Yokomastu2000].
Combination of Risk control and financing measure is important!
Needs for integration

Observations and IssuesDisaster related losses are increasing in the world.Less developed countries are more vulnerable and have less insurance coverage. Proactive disaster risk management is ideal but difficult in practice in developing countries.
How can we overcome such problems?

Disaster Countermeasure Basic Act (1961)
The immense damage caused by the Typhoon Ise-wan in 1959 was a turning point for disaster management, giving rise to a movement to plan and prepare a comprehensive disaster management system, and in 1961, the Disaster Countermeasures Basic Act was enacted. Thereafter, the disaster management system has been improved and strengthened following the occurrence of large natural disasters and accidents.

Disaster Management SystemsOrganizational Change in the National Government
At the time of the reorganization of the Central Government in 2001, the Cabinet Office undertook the administrative duties for disaster management. The Director-General for Disaster Management is mandated to undertake basic policy making and planning, coordinate the activities of all ministries and agencies and respond to large-scale disasters. In addition, the position“Minister of State for Disaster Management” was newly established as the Minister State for Special Missions.

Natural Hazard →DisasterConsequences ofHuman Behavior
Hazard: Flood, Earthquakes,,etc
Population & AssetExposure:population and asset
exposed to the threat of natural hazards
Vulnerability: degree of resistance of the asset & population against disaster

Benefit of Mitigation can be different. It depends on the possibility of risk transfer [ Kobayashi & Yokomastu 2000].
Combination of Risk control and financing measure is important!
Needs for integration

Low Frequency ⇒ difficulty in learning from the past experience⇒ existence of perception bias⇒ unknowns & uncertainties, ambiguities
High Impact (correlation in space and time)⇒ Importance of pro-active preparation: RISK MANAGEMENT⇒ Low insurability⇒ Long-term effects and Spill-over effects in space
Changes in Disaster Environment⇒ Urbanization, Globalization ⇒ Sustainable Development
