OxCGRT-Based Evaluation of Anti-COVID-19 Measures Taken by Japanese Prefectures

Abstract

Particularly in the early stages of infection spread in spring 2020, mass infection to COVID-19 occurred mainly in densely populated areas. In order to control the spread of the disease while minimizing its impact on economic activities, response and awareness-raising were required not only at the national level but also at the prefectural level. In this study, we attempted to compare and verify the characteristics of the decision-making process and the effectiveness of the prefectural response by quantitatively evaluating the changes in the measures taken by each prefecture in Japan over time.
