Spectral study of COVID-19 pandemic in Japan: The dependence of spectral gradient on the population size of the community.

Spectral study of COVID-19 pandemic in Japan: The dependence of spectral gradient on the population size of the community.

We have carried out spectral analysis of coronavirus disease 2019 (COVID-19) notifications in all 47 prefectures in Japan.
