I received this notice in my mailbox announcing the 2020 census last Saturday, but I did not get the actual survey packet with my identification number. I went online to respond to the survey, but wasn't able to without the identification number.
Friday evening, the actual packet with ID number was delivered. The packet material is in Japanese, so it was too difficult to fill out the paper form. Luckily, the online form is available in many languages. I chose English, of course, and was able to answer the 16 questions in just a few minutes. I'm glad that is done!
In Japan, the census is taken every five years and covers everyone that has lived or plans to live in Japan for more than three months, regardless of nationality. Everyone that is covered is legally obliged to respond. Here is my post about the 2015 census.
