“Pay it forward” and Altruistic Responses to Disasters in Japan: Latent Class Analysis of Support Following the 2011 Tohoku Earthquake

Abstract

Since the emergence of borantia (volunteers) in 1995, Japanese society has developed disaster volunteerism to enable citizens to help one another. Survivors from areas affected by disasters over the past two decades have returned to assist survivors of the Great East Japan Earthquake (2011 Tohoku Earthquake) through volunteering. This chain of support is known as a “pay it forward” network. Using latent class analysis, this article statistically demonstrates that different patterns of support behavior appeared after the 2011 Tohoku Earthquake and that people who were supported by others following disasters were more likely to help (e.g., through volunteering, donating goods, etc.). The class characterized as “pay it forward” was found to display high-support behaviors, and this was not only explained by traditional theory (i.e., dominant status model, resource model), but also by theories related to economic status and educational background. Results indicate that developing volunteerism in Japan accelerates network support.
