1. Disaster prevention and disaster mitigation, and crisis management
Increasingly severe disasters

Research budget, Employees,
Organization

Imminent large-scale earthquakes
・The Great East Japan Earthquake occurred in March 2011, and the Kumamoto Earthquake occurred in April 2016.
・It is feared that in the future, large-scale earthquakes such as an earthquake directly under Tokyo and the Nankai
Trough Earthquake will occur.

The new stage *1

Conducting research and preparing
technology standards

・ In the past 30 years, rainfall throughout Japan has become more localized, concentrated, and more intense.
(In August 2014 massive sediment disasters occurred in Hiroshima City, and in September 2015 a severe flood disaster occurred
due to he rain in Kanto and Tohoku)
・ There is fear of a super typhoon like typhoon 30 that struck the Philippines in November 2013.
・ There is also fear of disasters caused by volcanic eruptions, etc. like the Mt. Ontake eruption of September 2014.
*1: The Ministry of Land, Infrastructure, Transport and Tourism considers conditions such as “clear changes in the waythat rain falls” and “nobody will be surprised by a large-scale eruption occurring at any time” as a “the new stage”. (See:
http://www.mlit.go.jp/saigai/newstage.html).

Vision for Reconstruction of Society with Awareness of Flood and Disaster Prevention*2

Support for disaster response

・The aim is to switch to soft measures with greater effectiveness from residents’ perspective to ensure that residents can sense riskby themselves and take refuge.
・In addition to precautionary measures against flooding, crisis management-type hard measures are introduced to reduce damage
when disasters do occur.
・Conferences are established at national, prefectural and municipal levels, with hard and soft measures promoted uniformly andsystematically.
＊2: Based on heavy rain in Kanto and Tohoku, etc., the MLIT established a new “Vision for Reconstruction of Society with Awareness ofFlood and Disaster Prevention”, making changes to ensure awareness of “the fact that facilities have limited capacity and that
there will certainly be heavy floods that exceed the capacity of facilities to provide protection”, with society as a whole needing to
be prepared for floods. (See: http://www.mlit.go.jp/river/mizubousaivision/index.html)

On April 14th and 16th, 2016, earthquakes measuring up to 7 on the Japanese earthquake scale occurred in the Kumamoto District of Kumamoto
Prefecture. Immediately after the earthquakes, the NILIM cooperated with relevant research organizations and took part in planning local support ineach field through the MLIT’s Technical Emergency Control Force (TEC-FORCE), formed an independent survey team, and dispatched a total of 323
personnel to the locality. (As of June 17th, 2016)
From FY2017, the “Kumamoto Earthquake Recovery Support Division” has been established to locally assist with recovery after the disaster,
contributing to quick restoration and recovery in harmony with the Kumamoto Restoration Office of the Kyushu Regional Development Bureau.

The NILIM is aiming to improve technological capabilities through acceptance of exchange researchers from regional
government bodies and private enterprises, etc., experience of research activities, etc., and lectures, etc. (41 exchange
researchers have been accepted as of April 2017.)●Hosting personnel from regional development bureaus
In order to improve the technological capabilities of personnel belonging to regional government bodies with local issues
through their professional duties, opportunities are established for them to enroll for a fixed period of time as researchersor research associates. Personnel who have acquired technical skills are active as core technicians in each region after
returning to their Regional Development Bureaus.

●Training young technologists
The NILIM trains researchers with advanced specializations looking ahead to the next generation.
●Support for local issues
In order for NILIM researchers to work together with the Regional Development Bureau to resolve issues that occur locally,
the Kumamoto Earthquake Disaster Recovery Research Division was established in the area affected by the Kumamoto
Earthquake disaster. Personnel are also being dispatched to the Kinki Regional Development Bureau Large-scale Sabo Disaster

Training in maintenance

From FY2014, it started giving centralized maintenance training for all theregional development bureaus, and its goal for the five year period from FY2014 toFY2018 is to train a total of 7,700 people jointly with other organizations in threefields: roads, rivers, and ports and harbors. To do so, the NIILM will assign teachers
to representative courses and at the same time will help with the preparation ofcommon national lecture documents and textbooks.

Technical training in bridge maintenance

The NILIM constantly provides national government agencies and regional government bodies etc. with technical support of various kinds forpolicy implementation and project execution. And it regularly responds to requests for consultation concerning problems encountered in the field
by, for example, giving advice concerning inspections of deteriorated bridges, or studying river improvement planning. (In FY2016, approximately
2,200 consultations were handled.)

In December 2014, the NILIM Technical Consultation Office was established. Covering all fields over which the NILIM is incharge, the NILIM Technical Consultation Office is a one-stop service that accepts consultations regarding all fields andfacilities.

Roles of the NILIM

International research activities
The NILIM is promoting international research activities based on the following three perspectives.

Perspective ① Improvement of the quality of research results

Research budget, Employees,
Organization

In order to deliver valuable research results, we reinforce understanding of foreign technical policy trends related to “disasterprevention and disaster mitigation, and crisis management,” “infrastructure maintenance,” and “productivity revolution” which
are important research themes of the NILIM. For this reason, we are gathering extensive information by actively participating ininternational conferences. Regarding particularly important fields, we utilize bilateral conferences and multinational cooperation
research frameworks to understand the detailed situation.

Perspective ② Exportation of infrastructures and systems

Conducting research and preparing
technology standards

The NILIM carries out activities according to the export policy of high-quality infrastructures as one of the governmental
institutions and contribute to the benefit of Japanese companies and the revitalization of domestic industry. Activities arecarried out through participation and information dissemination from the conceptual stage of the project, development ofsoftware infrastructure, support for companies engaged in exporting infrastructure, and bilateral research collaboration with
developing countries. We conduct cooperative activities particularly in Indonesia and Vietnam as focused countries.

Perspective ③ International contribution
The NILIM dispatches experts to technical cooperation projects, which are implemented by JICA in developing countries, anddispatches researchers overseas for reconstruction assistance surveys after large-scale natural disasters. Furthermore, we
accept trainees for engineers and administrative officials in developing countries related to land, infrastructure, and transport.
