Beware of suspicious visits or phone calls impersonating the Census!
In the 2025 National Census, from Saturday, September 20, census takers will visit each household in the city.
In the past, there have been cases during the survey period where individuals impersonating census takers visited households or made phone calls to fraudulently obtain personal information (such as age, gender, family composition, financial institutions used, and Pension receipt status) for the purpose of monetary fraud, known as "impersonation surveys."
Please be aware that cases of "impostor surveys" are expected to continue occurring. If you receive suspicious visits or phone calls claiming to be from the census, please contact the Inagi City Census Call Center at 0120-461-026.
