The Japanese General Social Surveys (JGSS) Project is a Japanese version of the General Social Survey (GSS) project closely replicating the original GSS of the National Opinion Research Center at the University of Chicago. It provides data for analyses of Japanese society, attitudes, and behaviors, which makes possible international comparisons. Respondents were asked about employment, family and household composition, education, entertainment, technology and Internet usage, status and opinions on mental and physical health, alcohol and tobacco use, life satisfaction, addiction, proficiency with English, voting behavior, opinions on political and social issues, taxes and government expenditure, views on burial, family beliefs and issues, trust in people and institutions, membership in organizations, volunteering, perception of their personal appearance, receiving help from others, and their neighborhood environment. Demographic questions included age, sex, marital status, household income, and religious orientation and behavior.
