As a result of the maiden name consolidation procedure


I wonder how people will react if I change my last name.
What will I have to go through?

I want to live under my maiden name.
I want to get married but keep my maiden name.

This is a solution to these problems.


・Merits and demerits of combining maiden names
・How to change your maiden name
・The reaction of people around you when you change your name


At the end of 2019, I (a man) got married and changed my last name.
The reason is simple: my partner has a child in elementary school.
However, there was no way I could accept it honestly, and I had been struggling for a long time.
Then the Ministry of Internal Affairs and Communications announced at the right time.
November 5, 2019, the maiden name system will be enforced!

We were very happy to know that we could both live with our maiden names.
We were both very happy that we could live with our maiden names, and I decided to change my name because it would have less impact on me.

Why do you want to keep your maiden name, and what are the advantages/disadvantages?

The disadvantage of losing your maiden name is that your entire existence under your maiden name will disappear from this world.
You will not be able to prove your qualifications, licenses, papers, patents, or any other records that you have written under your maiden name.
However, with the addition of your maiden name, you will be able to prove the existence of your maiden name.
This is the reason why the government says that writing your maiden name together with your family name will lead to women’s advancement in society.

My number card, resident card, and driver’s license.

As soon as our area of residence started to support the use of maiden names,
we immediately registered our marriage.
At the same time, we asked for our maiden name to be added to the register.
We were told that we would have to change our family register to our new name first.
Two days after we submitted the notification, we were informed that our request was accepted.
I went to the municipal office again to apply for my number card and to have my maiden name added to my resident card.
Then, I went to the city office to have a copy of my resident card printed on the spot.
This time, I went to the driver’s license center to apply for the registration of my maiden name on my driver’s license.
Each procedure took about 10 minutes, and I finished the whole process in half a day.
When I saw my maiden name stamped on my driver’s license.
When I saw my maiden name stamped on the card, I was relieved to know that I can now live with my maiden name.

I received the name change request form early in the new year

At the beginning of 2020, I received an envelope from my company.
The contents were a request form to change the name of the insurance card, a bank account for payroll transfer and labor bank.
At the end of the year, I showed them my driver’s license with my maiden name on it and asked them if I could continue to use my maiden name.
I showed them my driver’s license with my maiden name on it at the end of the year.

Dear Human Resources

I have completed the process of adding my maiden name to the list of names that started the other day.
I have completed the procedure of writing my maiden name as well. I’m sorry to trouble you so early in the year, but I would appreciate it if you could confirm this with your employer.
I apologize for the inconvenience this may cause you early in the year.
Thank you for your cooperation.

I had to change my name to my new one, despite having gone through the process of adding my maiden name…

A few days later, I received an answer… all the results were not supported, and I needed to change my name to my new one.

Dear customer

Thank you very much for your help.
I know about the maiden name thing. We have not been able to handle this yet. I’m sure you’ll be able to help us.
Thank you very much.

None of them would even consider me for an immediate answer…

In the end, the maiden name only means that you can prove your maiden name. It is up to the contractor to decide whether the contract signed with the maiden name can be kept as is.

And all of this had to be changed.
The joy of the end of the year was gone, and I had to change my name to my new one in agony.

Passport does not support maiden name, so I have to change my name to my new one.

Passports have always been able to be processed with both maiden names.

But there’s a problem with this.
Although it is written in parentheses on the paper, the IC chip does not contain the information of the maiden name.
This has led to a number of problems, such as invalid airline tickets purchased under the maiden name, and credit cards in the maiden name not being accepted in foreign countries. There have been a number of problems.
Since nothing has changed in this regard, people who go abroad for travel or business trips will have to change their name to their new one.

There is no value in being able to register your maiden name with your maiden name’s seal.

This time, with the addition of your maiden name, you can now choose to register your seal with either your maiden name or your new name.
However, if you choose to register your seal with your maiden name, it is not worth it to register your seal with your maiden name if you are required to change the name of your bank account, like the bank account I mentioned above….

Conclusion: so far, doing the maiden name thing hasn’t helped! →It helped!

“I see that you are applying for a maiden name change, then you can keep your maiden name!”
…I don’t expect to get this kind of answer at all at this point.

I don’t think this will change in the future unless there is a direct recommendation or action taken by the government against companies that do not support the use of maiden names.

My maiden name was helpful in dealing with the tax office!

When I closed my bank account under my maiden name, I found that the maiden name was not useful.
It still seems to work only in government offices.

These results suggest that

The use of maiden names is not widespread in the private sector, but it is useful when dealing with government agencies.

Aside – Did you get adopted as a son-in-law? ~.

Why did your husband change his last name? Is he a son-in-law?
If he’s your son-in-law, he’ll help you with the household chores and also take good care of the kids, right?

No, I’m not a son-in-law, but there were a lot of things that happened and the other side changed it, haha…
(Talking about this again… and what is the image of a son-in-law like?)

This was asked very often at work, by my wife.
In Japan, the percentage of men who change their name after marriage is said to be 4%, so…
It’s definitely a minor issue.

It has nothing to do with the maiden name combination, but I found out that when a man changes his last name in an in-house marriage, why the questions are focused on the wife’s side.
And then my mood got worse and worse, and I spent a lot of time listening to her complain at night… lol

The procedure for changing my name was simply a matter of checking my wife’s clan in the box for which surname to take on the marriage certificate.
Adopting a son-in-law indicates that you have adopted a child from the other family, not necessarily that the man has changed his last name = adopted a son-in-law.


・I have added my maiden name to my resident card, driver’s license, and my number card.
・Passports are not subject to the combination of maiden names.
・When a man changes his name, there are many questions from people around him.

I can only hope that the combination of maiden and surnames will be an opportunity for Japan to become a society where couples can choose to use different surnames.
