Home inspections in Tokyo do sometimes occur

A person from south-east Asia, who is currently going through the naturalization process in Tokyo, has been communicating with Becoming legally Japanese throughout the process. They wish to remain anonymous for now (most do until they are accepted), but they sent me us interesting update the other day that I was given permission to share:
I just had my final interview (hopefully) at the Tokyo Homukyoku and house inspection this morning after submitting my application at end of April. The case officer went through my papers asking why I moved addresses and motives behind switching from one company to another - followed by having me fill-out a form stating I will give up my US and [southeast Asian country] nationalities once I naturalize to Japan. He then told me to go home first and came about 30mins after I got back. The home inspection was less than 5 minutes and had none of the going through your fridge rumors.
Some comments:
  • I had figured that home inspections occurred less often in Tokyo because of the case load (based on the other reports of how un-busy the other naturalization offices seem to be, even the ones in big international cities like Osaka) makes it prohibitively time consuming.
  • The fact that the "inspection" was less than five minutes pretty much says to me the purpose of the visit is to simply verify that what's written on paper, your home address, corresponds with reality.
  • Normally, the country this person mentions is required to renounce their citizenship prior to receiving Japanese nationality. However, because this person is a dual-national, and one of those nationalities is the U.S., which requires the loss of citizenship after naturalizing, the other nationality is permitted to be done post naturalization as well.

    This is interesting in that I always wondered what happened if you had more than one nationality and the renunciation/relinquishment/abandonment rules were different for each country. Apparently, if one of the nationalities (i.e. the U.S.) needs post naturalization proof, they allow all the additional nationalities to be renounced afterwards as well.
The final form the person is talking about is the Oath to Renounce, which Americans sign in addition to the Oath to obey the Japanese constitution and Japan's laws.

From the process this person is describing, it looks like they have a few more months to go before they get the (probable) approval from the Minister of Justice.

Good luck!
