Who this article is forA full-time homemaker whose Japanese husband died and who inherited his estate asks if she can apply with no work record.

Answer

Even with no work record, filing for naturalisation on the basis of inherited assets is entirely possible. The requirement to be able to make a living is not judged on employment income alone. If you can show that your assets keep your living stable, you can apply without waiting to build a work record.

What is this enquiry about?

A full-time homemaker whose Japanese husband died and who inherited his estate asks if she can apply with no work record.

Subject: naturalisation (普通帰化, ordinary naturalisation)
Situation: The enquirer changed her 在留資格 (status of residence) to 在留資格「永住者」 (Permanent Resident) while her Japanese husband was alive. He died last year, and they had no children. Her husband had no parents and no brothers or sisters, so she inherited his whole estate, including their flat and his savings, and she has already paid the inheritance tax. She was a full-time homemaker while her husband was alive, so she has no work record, but the inherited assets mean she has no trouble living.
Question: Does she have to start working and build up 3 years of record before she can apply for naturalisation? If she explains that her assets keep her living stable and that she plans to work in future, is there a way forward? Or would it be better to build up even 1 year of work record first and then apply?

Can I apply with assets even without a work record?

Yes, you can. The requirement is judged on more than employment income: assets and skills count too.

One of the naturalisation requirements is 「独立の生計を営むに足りる資産又は技能を有すること」, that is, having sufficient assets or skills to make an independent living. This asks whether the applicant can live stably in Japan, with the financial strength to live without relying on the national or local government. This requirement to be able to make a living is judged by looking at employment income, assets (savings, real estate, shares and so on) and skills together.

Ample savings: if you hold a lot of assets that can easily be turned into cash, that alone may be judged enough to keep an independent living. A balance certificate can prove that your financial base is stable.
Owning your flat: if you own it, you pay no rent, and your living costs are much lower. A 登記事項証明書 (certificate of registered matters) for the property and a 固定資産評価証明書 (fixed asset valuation certificate) can prove this.
Legitimacy of the inheritance: inheriting assets through circumstances beyond your control, and paying the inheritance tax properly, is not a factor that leads to denial.

Do I have to build a work record before I apply?

You do not necessarily have to build a work record before applying.

The requirement to be able to make a living is judged on assets or skills. So where you have ample assets, you may be assessed as having a base for living that is as stable as a steady income from work, or even more stable. If you were to apply after starting work, you would need a certain period, usually 1 year or more, to prove a steady income and a record of paying tax. Where your assets are enough to support you, one view is that you do not need to put your application off for that.

That said, your plan to work in future is worth presenting positively in the naturalisation application, as your plan for the life ahead of you. Willingness to work shows an intention to contribute as a member of Japan into the future, and it may be assessed as a plus.

What preparation do I need for the application?

A full statement of motivation, proof of your assets, and proof of good conduct matter most.

Writing the 動機書 (statement of motivation): set out your life so far in order of time, and show concretely how you want to live in Japan, how you will manage your assets, your plan for the life ahead of you, and your willingness to work.
Proof of assets: submit every certificate for the assets you inherited, leaving nothing out. That means bank balance certificates for each account, the 登記事項証明書 for the property, and balance certificates for securities. Attach the inheritance tax return and the tax payment certificate as well.
Proof of good conduct: gather documents showing that you have properly paid residence tax and your pension and health insurance contributions. Also submit documents showing that you have no traffic offences and no criminal record.

Because inheritance is an unusual circumstance, drafting a 理由書 (written explanation) to back up your documents needs specialist know-how. If you are worried, you are advised to consult a specialist (a gyoseishoshi).
