Response of the Japanese to COVID-19 and its vaccine was investigated with time-series questionnaire surveys conducted on December 2020 [N=2,500], February 2021 [N=1,500], June 2021 [N=2,500], and October 2021 [N=1,500]. The results showed that on December 2020 less than half of the respondents wanted to receive COVID-19 vaccination and about one fifth of them refused it. High anxiety led intension of the vaccination. On October 2021 three fourth of people in Japan had received the vaccination, and the most of respondents perceived COVID-19 vaccine very safe and beneficial. However, about 10% of respondents seemed to stick refusing the vaccination through all the surveys, and COVID-19 brought diversity of life-styles. Suitable and sufficient risk communication would be needed.
