Disaster Prevention and Reduction Research Committee

The “Complete Record of Five Years of Survey and Researchby the National Institute of Land and Infrastructure Management
Related to the Great East Japan Earthquake”, which is a record of allactivities of the NILIM related to the Great East Japan Earthquake,
was published at the end of September 2016.
More than 5 years have passed since the Great East Japan Earthquake.
During this period, the Ministry of Land, Infrastructure, Transport andTourism has been revising technology standards and guidelines in lightof new knowledge gained from damage inflicted by the earthquake.
In September 2016, the NILIM published the “Complete Recordof Five Years of Survey and Research by the National Institute ofLand and Infrastructure Management Related to the Great East Japan
Earthquake”, which is a systematic record of surveys and research
led by the NILIM to provide the grounds for the revision of technicalstandards and guidelines.
This research report presents lessons concerning responding to thetwo threats, earthquakes and tsunamis, based on the severe damage
caused by this giant magnitude 9 earthquake and the tsunami, fromtwo perspectives: hard (structures) and soft (systems and procedures)
measures. The report looks into matters in many fields which are
the responsibility of the Ministry of Land, Infrastructure, Transport
and Tourism, including wastewater management, rivers, seashores,
sediment disasters, road traffic, road structures, buildings, housing,cities, coastal protection, ports, airports, and social capital management.
Part I, which gives an overview of the relations between eachtype of survey research, positions the material in Part III Disastersurveying and Part IV Achievements of the Research, and clarifies
their interrelationships and a comprehensive perspective that includes
cross-sectoral initiatives.
In order to accelerate the restoration as the response to the Great
East Japan Earthquake transitions from the period of concentrated
restoration to the period of restoration and creation, we hope this reportwill be used to support restoration and reconstruction following the
Kumamoto Earthquake and contribute to the prevention and reductionof disasters in the future.

small-scale residential land improvement project etc.), and 4) studying
basic plans for candidate damaged public housing for the project.
The technical guidance is given in cooperation with the Building
Research Institute, and on the scene, jointly with the Kyushu Regional
Development Bureau and Kumamoto Prefecture. Liaison andcoordination meetings attended by representatives of cities, towns, andvillages in the disaster region are held periodically. The local governmentsin the disaster region share the details and results of studies conducted ineach municipality. The technical guidance will continue until the end of
this year. Later reports will cover the achievements of the support.

■■Participation in the Activities of the International Civil Aviation Organization (ICAO)
Airport Department, Airport Planning Division

The NILIM takes part in international conferences held to discuss
the planning of facilities, and international standardization offacilities, such as widening airport runways in order to help ensure
the safe operation of aircraft.
The International Civil Aviation Organization (ICAO) enacts
international technical standards for aviation as annexed documents to
the Convention on International Civil Aviation (Chicago Convention).
To revise standards and to enact new standards, expert committees called“Panels” are established for each matter studied, and within each Panel a
Working Subcommittee performs the actual revision and enactment work.
In the Panels and Working Subcommittees, “Advanced and detailed
technology studies” are conducted, accompanied by deliberations
and negotiations concerning proposed revisions to the AnnexedDocuments to the Convention. Regarding airports, researchers from2

have met five times and held active discussions. An Aerodrome Design
and Operations Panel meeting held in November deliberated a proposed
revision to an annexed document of the Convention that had been placed
before the panel, and an agreement was reached at the experts level.
The NILIM will continue to participate in the Panels and Working
Groups.

■■Build a Bridge with Cardboard Contest held

The Ministry of Land, Infrastructure, Transport, and Tourism performs
nearly real-time (delay of 1 or 2 min) public distribution of highresolution (resolution: 250-m meshes, distribution interval: 1 minute)radar rainfall information based on XRAIN, which can clarify localized
and abrupt heavy rain, which has been increasing steadily in recent years.
Until now, XRAIN consisted solely of X-band MP radar rain gauges, but
their radio waves attenuated easily, leaving some areas unmonitored. The
performance of conventional C-band radar rain gauges, which observed
nationwide rainfall at 5-minute intervals in 1-km meshes, was improved(given MP capability), and they have been equipped with technology
developed by the NILIM to permit them to be combined with X-band
MP radar rain gauges. As a result, at the same time as the XRAIN
distribution area has been greatly expanded, areas omitted by the former
XRAIN system are now covered by the C-band MP radar rainfall gauges,
thus stabilizing observations. Please take a look at the trial operation of
XRAIN (expanded trial version) that is now in progress.

Local government bodies in the Kumamoto Earthquake disasterregion must carry out restoration and reconstruction of damaged
homes and hamlets, but many cities, towns, and villages do not haveenough know-how and manpower to do so smoothly.
Therefore, the Housing Department is providing technical guidance tocities, towns and villages in the disaster region and to consultants involved
in restoration work in response to a request by the MLITT in a program
implemented this year by the MLITT Housing Bureau: Restoration
Survey of Homes and Hamlets in the Kumamoto Earthquake Disaster
Region. The surveys are conducted in 10 cities, towns, and villages
designated as severely damaged regions (Aso City, towns of Minamiaso, Nishihara, Ozu, Mashiki, Mifune, and Kosa, Uto City, Uki City,and Kashima Town) which have a particularly great need for assistance.
The goals of the surveying are 1) clarifying the intentions of disastervictims regarding home reconstruction, 2) preparing basic guidelines
for restoration, etc. of homes and hamlets, 3) studying the applicationof specific construction methods (housing environment improvement
projects such as damaged public housing improvement projects andthe meetings, research results and knowledge are used in order toensure the safe operation of aircraft at airports.
At present, the revision of the Airport Standard Code, which provides
the basis for the fundamental specifications of key airport facilities, andthe revision of other important specifications such as runway widths
are being discussed. During the past year, the Working Subcommittees

the NILIM Airport Department participate as advisors to the Civil
Aviation Authority executives who conduct negotiations, and throughThis year’s Build a Bridge with Cardboard Contest was the 23rd ina series that has been held every year since 1994. This contest is held
to encourage elementary school children, who will lead Japan in the
future, to learn the importance of bridges and other civil engineering
infrastructure that supports their daily lives through creative activities.
Until last year, the participants were grade 5 pupils in elementary
schools in Tsukuba, but from this year, both grade 4 and 5 pupils cantake part. As a result, 596 entries made by 657 pupils at 34 elementary
schools were submitted, almost doubling the number of participants overthe previous year. (Last year’s participation: 340 entries by 379 pupils)
The contest was announced at the end of May and the children madetheir entries as summer holiday assignments.
The construction conditions were strict: the major bridgematerial must be no more than two sheets of constructionuse cardboard, it must cross a river that is 30 cm inwidth, and it must bear a load of 1 kg. Nevertheless, thechildren were extremely ingenious and almost all satisfied
the conditions. From among those, the five members of
the screening committee evaluated their “expression ofindividuality”, “soundness and stability as bridges”, andthe “beauty of their shape, color, and finish”, and awarded

first prizes (3 works, photo 1), structural design prizes (5), aesthetic
design prizes (5) and prizes for effort (5). In addition, school incentive
prizes were given to six schools with the highest participation rate of
their registered students.
The prizes were awarded at the Civil Engineering Day Open House
2016 that was held on November 19 (Sat.). (Photo 2)
At the award ceremony, the children who won first prize talked
about the innovative methods they used to create their entries and thethought they put into each one.
We are looking forward to many elementary school pupils submitting
good entries again next year.

Planning and Research Administration Department, Planning Division
Administration Coordination Department, Planning and Coordination Division

The NILIM undertakes research on infrastructure that will create
the society of the future.
In its approximate budget request for 2017, in addition to 12
ongoing challenges, it requests budgets for 6 new challenges in 2
fields (230 million yen: including 12 ongoing challenges).
○○Disaster Prevention, and Disaster Mitigation and Crisis Management- Engineering Research on reinforcement of flood-fighting activities
It is predicted that climate change will increase the frequencyof flooding that exceeds the capacity of disaster prevention
measures, resulting in greater need for flood-fighting activities toreduce damage, so the NILIM will develop methods of assessing
the amount of labor and time needed for flood-fighting and its
effectiveness and will also develop technology to clarify locations
where flood-fighting activities are particularly necessary in order tomake such activities more efficient.
- Development of facility improvement technologies to ensure the healthand safety of disaster victims while they are in evacuation centers.
The NILIM will propose specific methods of ensuring living
environments and safety in evacuation centers set up following
huge disasters, improve evacuation centers considering the living
environment, and help secure the health and safety of evacuees in
evacuation centers.
- Developing traffic passability diagnosis technologies during city
fires caused by an earthquake
To prepare for huge disasters, the NILIM will develop technologies
to evaluate the passability of roads in the event of city fires caused

by a major earthquake, and support advance measures to enhance
the initial response and improve urban districts in order to reduce theinfluence of fire on evacuation and on passage of emergency vehicles.
- Research on methods of promptly inspecting and restoring airport
pavement following an earthquake disasterIn order that airports in disaster regions can quickly serve as bases for
emergency transport, the NILIM will establish judgment standards thatallow airport administrators to quickly inspect their airport pavementfor damage and to select a restoration method.
○○Regional Revitalization and Livability Improvement-
Development of urban structure analysis and evaluation
technologies based on diversifying daily life support functions
In order to further improve the sustainability and productivity ofcities, the NILIM will develop subjective analysis and evaluation
technologies for effective urban structures according to thecharacteristics of each city or region, and also will verify the possibilityof reforming urban structures according to their functions based on
the latest trends in life support functions, which are diversifying.
- Research on facade design methods intended to lower the energy
consumption of buildings
To further advance the energy-saving capability of buildings, the
NILIM will aim to establish facade design methods that can reduce
the load of equipment and machinery.
* Facade design = outer shell design including outside walls, roofs, windows, etc.
