Introduction

Many foreign residents in Japan who hold the status of residence “Long-Term Resident” worry that having many dependents, such as a spouse, children, or parents, might negatively affect their extension of period of stay or application for permanent residence.
In practice, however, immigration authorities focus more on the stability of the household finances—specifically, whether the household is running a deficit and whether the family can maintain a stable life in the future—rather than just the number of dependents.

This article explains, with reference to official information and public guidelines, how to think about the income and expenses balance when you have many dependents, focusing on the status of residence “Long-Term Resident”.

Basic framework of Long-Term Resident status and income

According to the official website of the Immigration Services Agency of Japan, “Long-Term Resident” is a status of residence granted by the Minister of Justice to those who are allowed to reside for a certain period, taking into account special circumstances.
The official explanation does not present any fixed numerical income standard such as “annual income of XX yen or more”, which shows that the authority evaluates each case comprehensively.

On the other hand, the guidelines for permanent residence state that an important requirement is that the applicant “has sufficient assets or skills to make an independent living without becoming a burden on the public and is expected to lead a stable life in the future”.
This means that for both extension of Long-Term Resident status and permanent residence applications, the key question is whether the household can maintain an independent and stable life, rather than simply whether the income exceeds a specific threshold.

Are many dependents really a disadvantage?

Focus on “stability of life”, not just “number of dependents”

In the permanent residence guidelines, one of the legal requirements is that the applicant has “sufficient assets or skills to make an independent living”.
What immigration officials actually check is not the number of dependents itself, but whether the income and assets are sufficient for all family members to maintain a stable life.

Therefore, even if you have many dependents, as long as the household income is sufficient and your monthly budget is not in deficit after paying rent and other living expenses, having many dependents does not automatically lead to a negative evaluation.
Conversely, even with only a few dependents, if the household is constantly running a deficit or has unpaid taxes or social insurance premiums, the stability of the household may be questioned.

No official cap on the number of dependents

Neither the published information from the Immigration Services Agency nor the permanent residence guidelines stipulates any maximum number of dependents such as “you may have up to XX dependents”.
There is also no official rule stating that “an application will be refused if there are many dependents”. Instead, each case is evaluated comprehensively in light of income, expenses, and other factors.

That said, it is a simple fact that more dependents mean higher living expenses, so with the same income level, households with more dependents tend to be evaluated more strictly in terms of whether they have enough financial room to live on.

How to think about the income–expenses balance

Organize your household finances, not only the income amount

In practice, for permanent residence, an annual income of around 3 million yen is sometimes referred to as a rough benchmark for a single person, but this is not a legally defined figure.
Many practitioners point out that when the applicant has dependents, the “desirable income level” increases according to the household size, since living costs grow as the family gets bigger.

At the same time, the Immigration Services Agency evaluates the stability of the household based on multiple documents such as household income, assets, employment situation, and the payment of taxes and social insurance premiums.
Therefore, when preparing to apply, it is useful not only to look at the annual income itself but also to organize your finances from the following viewpoints.

• Monthly net income and whether you receive bonuses
• Fixed costs such as rent or mortgage and utility bills
• Variable expenses such as food, education, communication fees, insurance, and medical costs
• Whether you can save money every month (surplus or deficit)

Tax deductions and social insurance aspects

If your family members meet the conditions for being dependents for tax or social insurance purposes, you may benefit from income tax and resident tax deductions, and reduced social insurance contributions.
For example, taxpayers with qualifying dependents can claim dependent exemptions on their taxable income, and in some cases, social insurance dependents do not need to pay additional health insurance or national pension contributions.

However, “lower taxes” does not mean that “a low income is acceptable”, and immigration officers consider overall financial stability while also checking how taxes and social insurance premiums have been paid.
The more dependents you have and the heavier your living costs become, the more important it is to manage your household finances and be able to explain your saving situation.

Example case to visualize the balance

Below is a hypothetical example to help visualize the situation in which a Long-Term Resident is supporting a family.

• Main person: Holds “Long-Term Resident” status and works in Japan
• Spouse: Full-time homemaker with no income
• Children: Two elementary school children
• Household income: Only the main person’s salary, a little above 4 million yen per year

In this scenario, the household must cover living expenses and education costs for four people, but if after paying rent and other expenses the family can still save a certain amount every year, the household will likely be evaluated as having a relatively stable life.
On the other hand, even with the same income level, if the rent is very high, loan repayments are heavy, and the household is constantly in the red with no savings, immigration authorities may take a more cautious view of the stability of the household.

Thus, even with the same family composition and income, the evaluation can differ depending on how the monthly household budget works, so keeping records such as household accounts and bankbooks that show a stable lifestyle can be very helpful.

Reviewing dependents and preparing documents

Confirm whether each dependent should really be treated as such

The permanent residence guidelines show that past receipt of public assistance and non-payment of taxes or social insurance premiums can negatively affect the evaluation of economic stability.
If you have many dependents, expanding the scope of dependents too much may make your household finances tight compared with your income and put pressure on your daily life.

Therefore, especially when including relatives living overseas as dependents, it is important to carefully consider whether you can clearly explain “how much money you send and how often” and “what impact these remittances have on your household finances”.
Continuing unnecessary or unrealistic dependent declarations may cause inconsistencies in your explanation, so you should proceed with caution.

Key documents to prepare for applications

For extension of Long-Term Resident status or permanent residence applications, the following documents are typically required to assess the applicant’s economic situation.

• Taxation and tax payment certificates issued by the local municipality
• Withholding tax statements, pay slips, and employment contracts
• Bankbooks or other documents showing savings
• Certificate of residence listing all household members

When gathering these documents, it helps if immigration officials can clearly see from them “how your income has changed”, “whether taxes and social insurance premiums have been paid properly”, and “whether your living expenses match your family composition”.
If necessary, preparing a simple written summary of your household budget and remittances to relatives can also make it easier for officials to understand your situation.

Conclusion

In examining applications for extension of “Long-Term Resident” status or permanent residence, immigration officers do not automatically treat a large number of dependents as a negative factor; instead, they focus on whether the household has an appropriate level of income for its family size and whether the monthly budget is not in deficit.
Therefore, the more dependents you have, the more important it is to prepare objective documents that clearly show the state of your household finances.

By understanding official guidelines and the framework of tax and social insurance systems, you can avoid focusing solely on the number of dependents and instead review your household finances from the perspective of whether your family as a whole can maintain a stable life.
If you have concerns about your individual situation, it is advisable to consult a specialist who can check the latest immigration practices and official information and discuss concrete figures and family composition with you.
