Although the sustainability of regional activities has been discussed in previous studies, such research tends to focus on strong leadership. On the other hand, this study attempts to introduce the concept of “platform” and “rule” in order to not overly rely on leadership. Moreover, the three examples, which occurred almost at the same time, are compared and then interpreted through the concepts of “platform” and “rule.” Finally, we concluded that these concepts are useful to promote regional activities and to contribute towards their sustainability.
