We conducted a questionnaire survey of 218 persons of 10s to 60s in Japan via the internet from 11^th to 14^th, December 2020, and obtained 200 valid answers. We grouped the respondents according to the adoption of the reduction to use plastic bags; 100 of those answered that they have reduced to use plastic bags (Group 1), 100 of those answered no behavior changes with charging (Group 2). Questionnaire includes questions related to the attempt to reduce plastic shopping bags, observing others' behavior, reuse behavior, pro-environmental habit, environmental risk perception, and a sense of community. We asked the respondents to state to what extent they carry out or concerned about above questions with 5-point Likert scale from 1 (strongly disagree) to 5 (strongly agree).
