Research Activities

The main theme of my study is “diffusion and improvement of effectiveness of business continuation management (BCM).” BCM means management activities to formulate and renew business continuity plans (BCPs), execute prior countermeasures, perform educations and exercises, and carry out continuous improvement. I was an official in charge of formulating the "Business Continuity Guidelines, 1st edition". After this, I opened an original introduction guide of BCP for small and medium enterprises on the website of my laboratory. I belong to the government committees, for example, in charge of evaluating and advising on BCPs of central government ministries. 

I research disaster reduction countermeasures such as a disaster management plans, systems and measures, and the disaster response exercises of enterprises and organizations. They are the important pair of business continuity, and both are necessary to execute properly. Therefore, I perform field hearings surveys to damaged enterprises and organizations, organize discussion meetings between industry, public and academia, and advise on fire drills and disaster headquarters exercises. Furthermore, I research on disaster volunteer activity, which is indispensable to support disaster victims, especially how to improve its activity environment and good relations with the governments.

As a recent study theme, I investigate the actions at the time of the Nankai Trough earthquake occurs, recovery and reconstruction systems, measures for the commuters who have difficulty returning home at a disaster time. In addition, I perform the instructional activities about disaster management and disaster response. I teach disaster policies and legislation, a lesson of the Great East Japan Earthquake and so on at our university, utilizing the 30-year experiences as an official of Cabinet Office and the Ministry in charge of Infrastructure. I also have many classes of BCP and disaster reduction countermeasures for enterprises and governments.
