By using a panel study method that followed the same cohort, this study collected nation-wide data on contemporary Japanese families as part of the National Family Research of Japan (NFRJ), organized by the Japan Society of Family Sociology. Beginning with 1,879 participants who responded to the NFRJ08 in January 2009, an annual postal follow-up survey was conducted; it was followed by a detailed survey for which respondents were visited. The response rate was between 80 and 90 percent, with complete data from all 5 surveys collected from 1,317 respondents.Around 40 members of the Society formed a research group that met two-three times per year to hold workshops on panel data analysis methods and review the results of the data analysis. Members of the research group also participated in data cleaning and some of the survey visits. A summary of this study along with details of the basic characteristics of the data was published as a report.
