[Abstract] The purpose of this research is to analyze the effects of lifting the state of emergency by collecting data of tweets in Twitter related to COVID-19. The Japanese government lifted it for Osaka, Kyoto and Hyogo on 21 May, for other prefectures on 25 May, 2020. This research was conducted from 21 to 30 May 2020. The results of text mining imply that tweets of the restart of economic activities can be observed through this period, and on other hand tweets which concern the emerge of infected persons by COVID-19 have already increased in the second half of this period.</datacite:description>
