Adaptation Strategies• We cannot control the Natural Hazards• Decrease the vulnerability (prevention)– Building Facilities physically stronger• Decrease the exposure (aversion)– Land-use control– Temporal pre-disaster evacuation• Increase the resilience (mitigation)– Back-up, storage, Response– Insurance, special finance

災災災

English nameIRIDeS
Iris, Iris laevigata or Japanese Iris：Symbol of hope and nobility
Logo meaning
It is the deformalized image of the Japanese character of disaster(災, wazawai) turned upside down, based on the idea of Japanese
saying "Turn your misfortune to good account".
It represents our mission of learning the lessons from the 2011
Tohoku earthquake and tsunami disaster and pursuing effective
disaster management to build sustainable and resilient societies.
Iris is the symbol of "hope" and "dignity".

New Building of IRIDeS
The new building is located on the westside of the Aobayama campus, in a quietlocation enclosed by green trees.
The five story RC building has
a seismic isolation system,
72-hour emergency power generation,
natural ventilation and light,
a balcony preventing direct sunlight.
It also has a space for conveying
information to visitors,
a multi-purpose hall for 150 people,
seminar rooms, a lecture room,
meeting rooms , a server room,
and a library room.
Most of the research labs have glass walls,
and each floor also features a common
space to enable researchers interact ions.

Kakeagare! Japan is a project that aims tohabitualize evacuation behavior in preparation
for a tsunami while tackling regional problems
based on the lessons learned from the Great
East Japan Earthquake. Tsunami evacuation
drill programs are being planned andimplemented in collaboration with industry,
government and academia, including IRIDeS.

特定プロジェクト研究

Meeting opportunities in IRIDeS
公開型の研究会の開催

The IRIDeS promotes publicly-offeredproject research with collaboratingorganizations from many countries andwith broad areas of specializations. The
aims of these research projects are not
only to contribute to on-goingrecovery/reconstruction efforts in theaffected areas but also to conduct
world-leading research on natural
disaster science and disaster mitigation.

IRIDeS will hold conferences and meetings
on a regular basis, in order to share anddisseminate our research progress andoutcomes, and to promote researchcollaboration and integration.

1～2年間の研究プロジェクトを公募し，学内の共同研究，国際連携研究，及び被災地・関連他大学との連携研究を推進しています．
公開報告会を年1回7月に実施しています．

IRIDeS Friday forum
A forum of regular presentations anddiscussions is provided in order to sharethe information of research activities andcollaborations at the IRIDeS. This forum
also reports emergency disaster surveys.
