The conclusion is a synthesis of the book. It examines how the Japanese adoption of social media increased during and after the Great East Japan Earthquake and Fukushima Daiichi nuclear power plant accident as both catastrophes acted as catalysts for this process. It suggests an important hypothesis of a possible number determining the lower threshold for maintaining a virtual community to be self-sustainable. It also lists the accomplishments of the Tsukuba Civic Activities Cyber-Square and explains how the introduction of social media into the local government of Tsukuba City has changed the municipal workers, the civil society and have led to the regeneration of new civic activities. This has led to a powerful regeneration of civil society in Tsukuba City.
