Outline of Great East Japan Earthquake Tsunami Disaster Recovery Support Survey of Damage Cities
(by the City Bureau of the Ministry of Land, Infrastructure, Transport and Tourism)
Objective: Supporting to make the recovery plans of damaged local governments by the Great East
Japan Earthquake and Tsunami Disaster
(1)Detailed understanding of the overall picture of the situation affected by the tsunami
(2)Analysis of the effect of implementation measures of hardware and software and disaster factor
⇒ to the basic data of the reconstruction plan study in the affected municipalities and review of reconstruction techniques
Period for investigation:2011 (fiscal year)
Survey objects:62 municipalities(6 prefectures)
Survey data were opened.
▼ First report(August 2011)
-“Immersion range of Tsunami " , " inundation depth " and " disaster damage status of buildings "
- Classification of the area affected by the disaster damage status
- The relationship of the disaster damage status of buildings and inundation depth
- Aggregate in each municipality
▼ Second report(October 2011)
- The relationship of the disaster damage status of buildings and inundation depth
(analysis by structure and floor)
- The relationship of human suffering and inundation due to tsunami
(analysis by place of residence and age)
▼ Third report(December 2011)
-Evacuation route and behavior until the Tsunami(maximum wave)reached

Outline of Archive of recovery support survey
Operator: CSIS, The University of Tokyo is managing this archive received the offer of data from the City Bureau of MLIT. (service started June 2012)
Purpose: The proposal “Hope Beyond the Disaster” of the Reconstruction Design Council
⇒ ○ importance of research on earthquake
⇒ ○ need for tradition and record of disaster
The basic policy for the recovery of the government
○ the implementation of a detailed surveillance study to contribute to future disaster prevention measures
○ to maintain a framework for collecting, storing, and publicly disclosing records and lessons learned from earthquake and tsunami disasters
○ to build a framework for the unified storage and utility of such records in such a way that they are accessible to everyone
The City Bureau of Ministry Land, Infrastructure, Transport and Tourism
⇒ on the outcomes of the " Great East Japan Earthquake and Tsunami
Disaster Recovery Support Survey of Damaged Cities" , to record properly and to be widely available
CSIS, The University of Tokyo
⇒ received the offer of data from the MLIT , operates the archive site

▼ The use for reconstruction plans and reconstruction community-development
- The realization of a certain disaster mitigation
▼ The use to the provision for the future, like the Nankai Trough Earthquake
-The steady evacuation plans
-Pre-reconstruction preparation plans
▼ The importance of the objective data and the fact
⇒ It is important to be remembered and recorded and to retrieve repeat.
（ It is important to be able toretrieve the data freely.
）
⇒ Then next is decision and behavior.
▼ pioneer of the use of open data (of government)
▼ in order to take advantage of the wisdom of the private sector in disaster prevention and reconstruction, it is also important to expose the limited data to the private sector
