Historical meaning of post-Fukushima social movements: Crisis in hegemony in postwar Japan and prefigurative politics in the 2010s

Since the Great East Japan Earthquake in March 2011 and the nuclear power plant accident, a number of movements have emerged in Japanese society, including the anti-nuclear power movement and others with a variety of agendas. The social movements of the 2010s in Japan have expanded along with the spread of social networking services and have brought together a new class of people who are different from those of the established movements. This article will compare and examine the social movements of the 2010s with those of the past, as well as the function they played in the social structure. In the early 2020s, a structural crisis in the political and economic foundations of postwar Japan has become apparent. The Japanese social movements of the 2010s were movements that pressed for the transformation of the old social system as well as the transformation of the old anti-system movements. Thus, this movement had the distinction of prefiguring a fundamental shift in the confrontational frame of reference between conservatism and progressivism that had shaped postwar Japan. This article will discuss the historical significance of the Japanese social movements of the 2010s in light of the structural factors behind the decline of the social base of both conservative and progressive forces.
