Abstract
Recently, there has been an increase in the number of “unreported” cases in the Population Census of Japan caused by nonresponses to the survey. Subsequently, this has led to data reliability challenges. In light of this problem, the factors related to the low response rate of the 2015 Population Census in the central Tokyo area are examined in the present study. An online survey was conducted among individuals residing in the three Special Wards of Tokyo to inquire about their responses (submitted or not submitted) to the previous census. The statistical analyses demonstrated that particularly in central Tokyo, middle-aged (35–49 years) people and those who did not own a single-family residence were more likely to be nonrespondents, while most of the other characteristics were similar to the results reported in a previous nationwide study. However, further studies are required to fully understand the high rates of unreported cases in central Tokyo.

Summary
Since 1920, the Population Census of Japan (administered approximately every 5 years) has provided basic statistics on the characteristics of Japan. This census is essential for comprehensive understandings of the historical changes and geographical variations of the residential characteristics of the country, such as family composition, housing, occupation, education, and mobility. The census is the only complete survey that targets the entire population residing in Japan. Households who did not submit the survey online by the deadline were provided with paper questionnaires for submission directly to enumerators, to a municipal office, or via postal mail. Each questionnaire required general household information (e.g., the number of members) and information on each person (e.g., age and occupation)
