Google community mobility data provides regional-level movement trends by location type (retail and recreation, grocery and pharmacy, parks, transit stations, workplaces, and residential) as a relative change from the day-of-the-week-wise average from January 3 through February 6, 2020. We obtained the daily national average of Google mobility in Japan in all location types but residential to measure the contact behavior of individuals outside the home.
