State of Emergency by Prefecture and Week. In this figure, a red cell indicates that the prefecture shown in the first column is in a state of emergency (SoE) in the week shown in the first row, running from the week of April 12, 2020, to that of October 3, 2021, whereas an orange cell indicates that it is in a semi-SoE. The weeks before April 12, 2020, and after October 3, 2021, are omitted because these periods had no SoE or semi-SoE. Data source: [34]
