Abstract
In this study, I investigated the business interruption caused by the Great East Japan Earthquake in each company of the manufacturing industry. I collected the data of approximately 1,300 domestic establishments, by surveying information of disaster-struck companies on the Internet and newspapers, etc.
As a result, approximately 10% of companies suffered the damage caused by Disaster of Supply Chain Networks. It became clear that the period to production recovery was two and a half months.
In addition, I analyzed about a relation between road traffic network and the production restoration of the manufacturing industry. The period of business interruption becomes shorter, when the transportation time from the supply base to the company becomes shorter.
