Happiness in Japan before and after the Great East Japan Earthquake

This paper presents the results of a panel survey (N=10744) that examines how the Great East Japan Earthquake of March 2011 has affected the happiness of young people in Japan outside of the afflicted area. Our dataset consists of Japanese in their 20s and 30s from all non-afflicted prefectures. We conducted two surveys on happiness – one before the earthquake (December 2010) and one after (March 2011). The results suggested that about half of the Japanese youth have changed their life values after the earthquake even though they were not in the afflicted area, especially in terms of valuing social connectedness and ordinary life. In addition, people who were thinking about the earthquake when they completed the second survey were happier after the earthquake, showing that reflecting on the earthquake had prompted them to reevaluate their definition of global happiness. They also experienced temporary negative emotional reactions more frequently after the earthquake.
