The procedure required in Japan before you can obtain a visa and move abroad is the ‘notification of moving abroad’.
In my case, I lived in Nerima Ward, Tokyo, so regardless of the duration of my stay, I had to submit this form if I was going to live abroad.
This needs to be submitted from two weeks before to two weeks after travelling abroad.
It is recommended to complete the procedure domestically as it is very difficult to submit it after travelling abroad.

What happens when I report moving abroad?
When you report moving abroad, your residence card treats you as ‘expelled’. This is the same as having removed your certificate of residence.
Tax (residential tax) treatment
Note that if you have a certificate of residence on 1 January due to Japanese tax treatment, you will have to pay residence tax and other taxes for that year.
If you cross over into another year when you travel to Japan, you may want to consider the hassle of paying the tax and submit it in advance.
If you want to provide a certificate of residence before the date of moving out
If you submit your residence card before the date of moving abroad, your residence card will be marked as ‘除票予定’. If you need to submit your residence certificate somewhere, it is advisable to check whether a statement of ‘除票’ will be officially accepted.
If you submit it after the date of moving abroad, it will be marked as ‘discharge’.
When applying for a certificate of residence expelled from abroad
First, it is not currently possible to apply from diplomatic missions abroad.
There are only two procedures. The first is to contact the municipal office of your place of residence for more information, as I have only heard about it.
・The first is to ask your parents to write a letter of attorney and send it to you by post.
・The pattern is to apply to the domicile of origin by international mail. Send a document with your identity and address, a return envelope and a return fee.
Procedures and requirements for notification of moving abroad.
Visit your local government office.
Try to be there in person as much as possible. Otherwise, you will have to write a power of attorney and bring it with you, which is quite difficult…
Make sure you can visit the office between the opening of the office and 4pm.
It is safer to leave a day open and visit in the morning.
Application for notification of moving abroad
Here is what you need. If you have a My Number card, that was all you needed to confirm your identity.
・Identification documents (My number card, Basic Resident Register card with photo, driver’s licence, passport (Japanese passport), etc.) of the person coming to the counter.
・My number card
・An email address where you can be contacted after moving out of the country.
At the Nerima Ward Office, the notification of moving abroad was made by filling in the following form and submitting it.
Here, just write ‘Portugal’ in the ‘new address’ field.
If you already have a new address outside the country, write it down.
I couldn’t put it down because I’m homeless now…
A subtle caveat is that the seal registration card associated with an individual will also no longer be available.
Ordinary people don’t usually create one, but those who have a legal entity will always have a seal registration card, so it would be a good idea to check this in advance. (Does the seal registration card just become unusable, but the seal registration remains? But it might not be there because it’s an expulsion form, I don’t know…)
Application for continued use of a personal number card outside the country
I received a mysterious comment from a government official: ‘I don’t know the advantages of continuing to use it outside the country, but you should do it.’ Although I still have some doubts, I have completed the procedure because I live a clean and proper life in accordance with the law.
I filled in the form ‘Application for Continued Overseas Use of Personal Number Card and Application for Revocation/New Issue of Electronic Certificate’. This will enable you to follow the procedures for non-residents and for overseas use.
Here, you will also need to provide an email address where you can be contacted after moving out of the country, so prepare this in advance.
Free addresses such as gmail are recommended. Note that if you use a carrier (e.g. ezweb), you will not be able to maintain it if you change carriers, or you will have to pay for it.
After submitting the documents, you can update your number in a private room to complete the process.
在外投票制度（overseas voting system）
Although it is not related to the application for an overseas transfer notification, there is an ‘overseas voting system’.
This is a system for those who want to participate in voting in Japan even if they live abroad! This is a system for those who want to participate in voting in Japan even if they live abroad. If you want to do this, you should apply in advance.
Summary
If you go on a weekday morning, the process will be smooth and may not take more than two hours.
There are many procedures for emigrating abroad, including visas, so I hope this helps anyone who needs help.
