Factors Affecting Household Disaster Preparedness Among Foreign Residents in Japan

Japan is a country known both for its devastating natural disasters and its high level of community preparedness. However, while demographic pressures stemming from an aging society have led to a growing foreign population, scholars have paid little attention to understanding the levels of disaster preparedness exhibited by this group. Using representative data from the 2015 Nagoya City Foreign Resident Survey, this article is the first to explore variations in household disaster preparedness among Japan’s foreign residents. Although numerous factors were found to affect preparedness, the most important appear to be national origin, experience with disaster training, and exposure to disaster information. Japanese language proficiency, perhaps surprisingly, was of minor importance. We thus argue that a person’s cultural background and their exposure to information about local hazards affect their ability to identify and assess risk, which increases the likelihood that they will prepare their household for emergencies. This study not only provides insight into what might drive preparedness activities within foreign populations but also helps explain how migrants obtain disaster information. Its main implication is that Japan’s disparate migrant populations require a strategically varied approach when considering interventions to address disaster vulnerability.
