Advancement and prevalence of coastal and marine technology
– Aiming to improve people’s lives and to ensure safety and security –

With a renewed awareness of the importance of countermeasures against earthquakes and tsunami after the Great East Japan Earthquake, Japan has been enhancing its strategic approach as a maritime nation. It has become increasingly important to promote the development, utilization, and preservation of Japan’s coastal regions and oceans, the maintenance of structures, and prevention of coastal disasters in order to bring prosperity and wealth to our country, make contributions to improve people’s lives and develop economic activities, and build a safe and secure society.
The Coastal Development Institute of Technology(CDIT) has so far addressed various challenges of coastal technology, conducting research, developing and disseminating new technologies since it was founded in 1983. CDIT will continue to participate in innovation of technologies to develop, utilize, preserve coastal areas and prevent disasters based on its advanced technology and with the assistance of industry, administration and academia. CDIT will thereby contribute to improvement of people’s lives and worldwide dissemination of technological information.

Research and investigation on prevention of coastal disasters

Since the Great East Japan Earthquake on March 11, 2011, we have conducted research and investigation on the causes of damage and the subsequent restoration of disaster-stricken port facilities, as well as the prevention and reduction of seismic and tsunami disasters caused by future massive earthquakes or large-scaletidal waves caused by heavy typhoons.

■Research and investigation of the causes of damage and restoration of port facilities stricken by the Great East Japan Earthquake


■Research on upgrading numerical simulation model for tsunami and storm surge

■Research on a new type of breakwater which enables co-existing of ship navigation and tsunami protection

■Research on GPS wave observation system※ to observe tsunamis, storm surges and waves at offshore, and on the use of collected data for disaster prevention purpose

■Research on the facilities for control of tsunami driftage

Research and Investigation on Construction Technologies for Ports and Harbors Coasts and Airports

CDIT conducts research on construction technology to safely and efficiently develop ports, airports and coastal facillties as well as well as reserch on the improvemnt of logistic infrastructure,material recycling and development of new energy.

■Research on construction technology of an offshore airport

Research on Maintenance, Management and Preservation of Coastal Structures

Social infrastructure, which was mostly developed during the period of Japan’s rapid economic growth, now requires massive renewal. It is crucial for coastal structures to be properly maintained, managed and preserved because they are placed in a severe environment such as salty water and consolidation settlement of soft ground. CDIT addresses these technological challenges and conducts necessary research.

Research and Investigation on Coastal Meteorology and Oceanography

CDIT conducts research on the analysis of long-period waves and harbor calmness etc. in the coastal area.
■Research on Yorimawari waves i.e., long-period waves traveling to Toyama Bay※, and analysis on harbor calmness based on Boussinesq equation※

Research on international standardization of design method etc.

It is important to disseminate information on designing method and other guidelines of Japan to the world. CDIT conducts research on overseas trend of international standardization of technical standards and dissemination of Japan’s design and technical standards while actively participating in international conferences.
