Background: Ibaraki’s Amabie-chan is a COVID-19 infection control system unique to Ibaraki prefecture, Japan. It requires residents to register each time they visit events, commercial facilities, and restaurants. The number of registrations has been limited, and its function alerting about people positive for COVID-19 infection seems not to be working. Nevertheless, registration with the system might have some impact on the user’s behavior. In the current preliminary survey, the possible impact of Ibaraki’s Amabie-chan on infection prevention behavior and fear of COVID-19 was investigated. Methods: A cross-sectional, web-based, anonymous, and self-administered survey was conducted at two workplaces in Tsukuba Science City, Ibaraki, Japan. The first survey was conducted at one of the workplaces in November 2020, and the second survey, at the other workplace in February 2021. Variables of interest were sex, age group, marital status, employment status, Ibaraki’s Amabie-chan use, COVID-19 Contact-Confirming Application use, ten items of infection prevention behaviors, and fear of COVID-19. Hierarchical linear regression analysis was performed. Results: In both surveys, use of Ibaraki’s Amabie-chan was significantly associated with COCOA use and with “physical condition management such as body temperature measurement.” No association was found with other infection prevention behaviors or with fear of COVID-19. Conclusions: Our findings did not provide sufficient evidence for the effectiveness of Ibaraki’s Amabie-chan in regard to users’ infection control behavior. Further detailed study is needed to investigate the effectiveness in terms of infection prevention and the cost-effectiveness of Ibaraki’s Amabie-chan.
