Abstract
In Japan the risk of natural disasters is high, and how to suppress the damage of natural disasters have been into question. So, Business Continuity Plan has received attention. It is important not only for own companies but also for our society to continue the daily life, and therefore companies, which make up the society, work on the introduction of BCP and enhance the capacity of business continuity. Spreading the introduction of BCP in small businesses is essential to enhance the resilience of the society, because, in particular, small businesses account for 99.7% of the number of companies in Japan, supporting the foundation of society and the economy. Therefore, in this study, using the practical experience of BCP and the theoretical framework of social dilemmas, I want to propose one policy to spread the introduction of BCP in small business.
