Japan National Census 2020

Poste date: Monday, September 28, 2020

Once every 5 years, the Japanese government conducts a nationwide Census which is to be the most important statistical survey. This year (2020) is the Census (Kokusei Chousa) year and the deadline of its submission is on October 7th. This Census covers everyone who has lived or plans to live in Japan for over 3 months, regardless of nationality. As the submission of the Census survey is required by law, the Bureau of Census provides their questionnaire in Japanese, English, Chinese, and other languages in order to make it easier for foreign residents to provide accurate information to the Census.

As explained on the official Census website 2020, the results of the survey will be used for measures such as city planning to make life easier for foreign residents. All responses to the Census will be used only for the purpose of creating accurate statistics and will not be used in any way for immigration control, police investigations, or other such purposes.

Hard Copies

A Census taker will visit and deliver the Census survey documents into your mailbox starting from September 14th, 2020.
